* \li Series 2 USB AVRs (AT90USBxx2, ATMEGAxxU2)
*
* \section Sec_Info USB Information:
*

*
* <table>
* <tr>
* <td><b>USB Mode:</b></td>
* <td>Device</td>

* </table>
*
* \section Sec_Description Project Description:
*
* This bootloader enumerates to the host as a CDC Class device (virtual serial port), allowing for AVR109
* protocol compatible programming software to load firmware onto the AVR.
*
* Out of the box this bootloader builds for the AT90USB1287 with an 8KB bootloader section size, and will fit
* into 4KB of bootloader space. If you wish to alter this size and/or change the AVR model, you will need to
* edit the MCU, FLASH_SIZE_KB and BOOT_SECTION_SIZE_KB values in the accompanying makefile.
*
* When the bootloader is running, the board's LED(s) will flash at regular intervals to distinguish the
* bootloader from the normal user application.
*
* \warning <b>THIS BOOTLOADER IS NOT SECURE.</b> Malicious entities can recover written data, even if the device
* lockbits are set.
*
* \section Sec_Running Running the Bootloader
*
* On the USB AVR8 devices, setting the \c HWBE device fuse will cause the bootloader to run if the \c HWB pin of
* the AVR is grounded when the device is reset.
*
* The are two behaviours of this bootloader, depending on the device's fuses:
*
* <b>If the device's BOOTRST fuse is set</b>, the bootloader will run any time the system is reset from
* the external reset pin, unless no valid user application has been loaded. To initiate the bootloader, the
* device's external reset pin should be grounded momentarily.
*
* <b>If the device's BOOTRST fuse is not set</b>, the bootloader will run only if initiated via a software
* jump, or if the \c HWB pin was low during the last device reset (if the \c HWBE fuse is set).
*
* For board specific exceptions to the above, see below.
*
* \subsection SSec_XPLAIN Atmel Xplain Board
* Ground the USB AVR JTAG's \c TCK pin to ground when powering on the board to start the bootloader. This assumes the
* \c HWBE fuse is cleared and the \c BOOTRST fuse is set as the HWBE pin is not user accessible on this board.
*
* \subsection SSec_Leonardo Arduino Leonardo Board
* Ground \c IO13 when powering the board to start the bootloader. This assumes the \c HWBE fuse is cleared and the
* \c BOOTRST fuse is set as the HWBE pin is not user accessible on this board.
*
* \section Sec_Installation Driver Installation
*
* After running this bootloader for the first time on a new computer, you will need to supply the .INF
* file located in this bootloader project's directory as the device's driver when running under Windows.
* This will enable Windows to use its inbuilt CDC drivers, negating the need for custom drivers for the
* device. Other Operating Systems should automatically use their own inbuilt CDC-ACM drivers.
*
* \section Sec_HostApp Host Controller Application
*
* This bootloader is compatible with the open source application AVRDUDE, Atmel's AVRPROG, or other
* applications implementing the AVR109 protocol, which is documented on the Atmel website as an application
* note.
*
* \subsection SSec_AVRDude AVRDUDE (Windows, Mac, Linux)
*
* AVRDude is a free, cross-platform and open source command line programmer for Atmel and third party AVR
* programmers. It is available on the the Windows platform as part of the "WinAVR" package, or on other systems
* either from a build from the official source code, or in many distributions as a precompiled binary package.
*
* To load a new HEX file with AVRDude, specify "AVR109" as the programmer, with the allocated COM port. On Windows
* platforms this will be a COMx port name:
* \code
* avrdude -c AVR109 -p at90usb1287 -P COM0 -U flash:w:Mouse.hex
* \endcode
*
* On Linux systems, this will typically be a /dev/ttyACMx port name:
* \code
* avrdude -c AVR109 -p at90usb1287 -P /dev/ttyACM0 -U flash:w:Mouse.hex
* \endcode
*
* Refer to the AVRDude project documentation for additional usage instructions.
*
* \section Sec_API User Application API
*
* Several user application functions for FLASH and other special memory area manipulations are exposed by the bootloader,
* allowing the user application to call into the bootloader at runtime to read and write FLASH data.
*
* By default, the bootloader API jump table is located 32 bytes from the end of the device's FLASH memory, and follows the
* following layout:
*
* \code
* #define BOOTLOADER_API_TABLE_SIZE 32
* #define BOOTLOADER_API_TABLE_START ((FLASHEND + 1UL) - BOOTLOADER_API_TABLE_SIZE)
* #define BOOTLOADER_API_CALL(Index) (void*)((BOOTLOADER_API_TABLE_START + (Index * 2)) / 2)
*
* void (*BootloaderAPI_ErasePage)(uint32_t Address) = BOOTLOADER_API_CALL(0);
* void (*BootloaderAPI_WritePage)(uint32_t Address) = BOOTLOADER_API_CALL(1);
* void (*BootloaderAPI_FillWord)(uint32_t Address, uint16_t Word) = BOOTLOADER_API_CALL(2);
* uint8_t (*BootloaderAPI_ReadSignature)(uint16_t Address) = BOOTLOADER_API_CALL(3);
* uint8_t (*BootloaderAPI_ReadFuse)(uint16_t Address) = BOOTLOADER_API_CALL(4);
* uint8_t (*BootloaderAPI_ReadLock)(void) = BOOTLOADER_API_CALL(5);
* void (*BootloaderAPI_WriteLock)(uint8_t LockBits) = BOOTLOADER_API_CALL(6);
*
* #define BOOTLOADER_MAGIC_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 2))
* #define BOOTLOADER_MAGIC_SIGNATURE 0xDCFB
*
* #define BOOTLOADER_CLASS_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 4))
* #define BOOTLOADER_CDC_SIGNATURE 0xDF00
*
* #define BOOTLOADER_ADDRESS_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 8))
* #define BOOTLOADER_ADDRESS_LENGTH 4
* \endcode
*
* From the application the API support of the bootloader can be detected by reading the FLASH memory bytes located at address
* \c BOOTLOADER_MAGIC_SIGNATURE_START and comparing them to the value \c BOOTLOADER_MAGIC_SIGNATURE. The class of bootloader
* can be determined by reading the FLASH memory bytes located at address \c BOOTLOADER_CLASS_SIGNATURE_START and comparing them
* to the value \c BOOTLOADER_CDC_SIGNATURE. The start address of the bootloader can be retrieved by reading the bytes of FLASH
* memory starting from address \c BOOTLOADER_ADDRESS_START.
*
* \subsection SSec_API_MemLayout Device Memory Map
* The following illustration indicates the final memory map of the device when loaded with the bootloader.
*
* \verbatim

* \endverbatim
*
* \section Sec_KnownIssues Known Issues:
*
* \par On Linux machines, the CDC bootloader is unstable or inaccessible.
* A change to the \c ModemManager module in many Linux distributions causes
* this module to try to take control over inserted CDC devices, corrupting the
* datastream. A UDEV rule is required to prevent this.
* See <a href=https://groups.google.com/d/msg/lufa-support/CP9cy2bc8yo/kBqsOu-RBeMJ>here</a> for resolution steps.
* If the issue still persists then uninstall modemmanager by executing <tt>sudo apt-get remove modemmanager</tt>, or
* the equivalent using your chosen distribution's package manager.
*
* \par On Linux machines, the CDC bootloader is inaccessible.
* On many Linux systems, non-root users do not have automatic access to newly
* inserted CDC devices. Root privileges or a UDEV rule is required to gain
* access.
* See <a href=https://groups.google.com/d/msg/lufa-support/CP9cy2bc8yo/kBqsOu-RBeMJ>here</a> for resolution steps.
*

* </tr>
* </table>
*
* \section Sec_Description Project Description:
*
* This bootloader enumerates to the host as a DFU Class device, allowing for DFU-compatible programming
* software to load firmware onto the AVR.
*
* Out of the box this bootloader builds for the AT90USB1287 with an 8KB bootloader section size, and will fit
* into 4KB of bootloader space. If you wish to alter this size and/or change the AVR model, you will need to
* edit the MCU, FLASH_SIZE_KB and BOOT_SECTION_SIZE_KB values in the accompanying makefile.
*
* When the bootloader is running, the board's LED(s) will flash at regular intervals to distinguish the
* bootloader from the normal user application.
*
* \section Sec_Running Running the Bootloader
*
* On the USB AVR8 devices, setting the \c HWBE device fuse will cause the bootloader to run if the \c HWB pin of
* the AVR is grounded when the device is reset.
*
* The are two behaviours of this bootloader, depending on the device's fuses:
*
* <b>If the device's BOOTRST fuse is set</b>, the bootloader will run any time the system is reset from
* the external reset pin, unless no valid user application has been loaded. To initiate the bootloader, the
* device's external reset pin should be grounded momentarily.
*
* <b>If the device's BOOTRST fuse is not set</b>, the bootloader will run only if initiated via a software
* jump, or if the \c HWB pin was low during the last device reset (if the \c HWBE fuse is set).
*
* For board specific exceptions to the above, see below.
*
* \subsection SSec_XPLAIN Atmel Xplain Board
* Ground the USB AVR JTAG's \c TCK pin to ground when powering on the board to start the bootloader. This assumes the
* \c HWBE fuse is cleared and the \c BOOTRST fuse is set as the HWBE pin is not user accessible on this board.
*
* \subsection SSec_Leonardo Arduino Leonardo Board
* Ground \c IO13 when powering the board to start the bootloader. This assumes the \c HWBE fuse is cleared and the
* \c BOOTRST fuse is set as the HWBE pin is not user accessible on this board.
*
* \section Sec_Installation Driver Installation
*
* This bootloader is designed to be compatible with Atmel's provided Windows DFU class drivers. You will need to
* install Atmel's DFU drivers prior to using this bootloader on Windows platforms. If you are using a 64 bit Windows
* OS, you will need to either disable the driver signing requirement (see online tutorials for details) or use a
* digitally signed version of the official Atmel driver provided by a third party AVR user at
* <a>http://www.avrfreaks.net/index.php?module=Freaks%20Academy&func=viewItem&item_id=2196&item_type=project</a>.
*
* \note This device spoofs Atmel's DFU Bootloader USB VID and PID so that the Atmel DFU bootloader
* drivers included with FLIP will work. If you do not wish to use Atmel's ID codes, please
* manually change them in Descriptors.c and alter your driver's INF file accordingly.
*
* \section Sec_HostApp Host Controller Application
*
* This bootloader is compatible with Atmel's FLIP utility on Windows machines, and dfu-programmer on Linux machines.
*
* \subsection SSec_FLIP FLIP (Windows)
*
* FLIP (Flexible In-System Programmer) is a utility written by Atmel, and distributed for free on the Atmel website.
* The FLIP utility is designed to assist in the bootloader programming of a range of Atmel devices, through several
* popular physical interfaces including USB. It is written in Java, however makes use of native extensions for USB
* support and thus is only offered on Windows.
*
* To program a device using FLIP, refer to the Atmel FLIP documentation.
*
* \subsection SSec_DFUProgrammer dfu-programmer (Linux)
*
* dfu-programmer is an open-source command line solution for the bootloader programming of Atmel devices through a
* USB connection, using the DFU protocol, available for download at <a>http://sourceforge.net/projects/dfu-programmer/</a>.
*
* The following example loads a HEX file into the AVR's FLASH memory using dfu-programmer:
* \code
* dfu-programmer at90usb1287 erase flash Mouse.hex
* \endcode
*
* \section Sec_API User Application API
*
* Several user application functions for FLASH and other special memory area manipulations are exposed by the bootloader,
* allowing the user application to call into the bootloader at runtime to read and write FLASH data.
*
* \warning The APIs exposed by the DFU class bootloader are \b NOT compatible with the API exposed by the official Atmel DFU bootloader.
*
* By default, the bootloader API jump table is located 32 bytes from the end of the device's FLASH memory, and follows the
* following layout:
*
* \code
* #define BOOTLOADER_API_TABLE_SIZE 32
* #define BOOTLOADER_API_TABLE_START ((FLASHEND + 1UL) - BOOTLOADER_API_TABLE_SIZE)
* #define BOOTLOADER_API_CALL(Index) (void*)((BOOTLOADER_API_TABLE_START + (Index * 2)) / 2)
*
* void (*BootloaderAPI_ErasePage)(uint32_t Address) = BOOTLOADER_API_CALL(0);
* void (*BootloaderAPI_WritePage)(uint32_t Address) = BOOTLOADER_API_CALL(1);
* void (*BootloaderAPI_FillWord)(uint32_t Address, uint16_t Word) = BOOTLOADER_API_CALL(2);
* uint8_t (*BootloaderAPI_ReadSignature)(uint16_t Address) = BOOTLOADER_API_CALL(3);
* uint8_t (*BootloaderAPI_ReadFuse)(uint16_t Address) = BOOTLOADER_API_CALL(4);
* uint8_t (*BootloaderAPI_ReadLock)(void) = BOOTLOADER_API_CALL(5);
* void (*BootloaderAPI_WriteLock)(uint8_t LockBits) = BOOTLOADER_API_CALL(6);
*
* #define BOOTLOADER_MAGIC_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 2))
* #define BOOTLOADER_MAGIC_SIGNATURE 0xDCFB
*
* #define BOOTLOADER_CLASS_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 4))
* #define BOOTLOADER_DFU_SIGNATURE 0xDF10
*
* #define BOOTLOADER_ADDRESS_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 8))
* #define BOOTLOADER_ADDRESS_LENGTH 4
* \endcode
*
* From the application the API support of the bootloader can be detected by reading the FLASH memory bytes located at address
* \c BOOTLOADER_MAGIC_SIGNATURE_START and comparing them to the value \c BOOTLOADER_MAGIC_SIGNATURE. The class of bootloader
* can be determined by reading the FLASH memory bytes located at address \c BOOTLOADER_CLASS_SIGNATURE_START and comparing them
* to the value \c BOOTLOADER_DFU_SIGNATURE. The start address of the bootloader can be retrieved by reading the bytes of FLASH
* memory starting from address \c BOOTLOADER_ADDRESS_START.
*
* \subsection SSec_API_MemLayout Device Memory Map
* The following illustration indicates the final memory map of the device when loaded with the bootloader.

* \endverbatim
*
* \subsection SSec_Aux_Space Auxiliary Bootloader Section
* To make the bootloader function on smaller devices (those with a physical
* bootloader section of smaller than 6KB)
*
* \section Sec_KnownIssues Known Issues:
*
* \par On Linux machines, the DFU bootloader is inaccessible.
* On many Linux systems, non-root users do not have automatic access to newly
* inserted DFU devices. Root privileges or a UDEV rule is required to gain
* access.
* See <a href=https://groups.google.com/d/msg/lufa-support/CP9cy2bc8yo/kBqsOu-RBeMJ>here</a> for resolution steps.
*
* \section Sec_Options Project Options

*
* The following list indicates what microcontrollers are compatible with this demo.
*
* \li Series 7 USB AVRs (AT90USBxxx7)
* \li Series 6 USB AVRs (AT90USBxxx6)
* \li Series 4 USB AVRs (ATMEGAxxU4)
* \li Series 2 USB AVRs (AT90USBxx2, ATMEGAxxU2)
*
* \section SSec_Info USB Information:
*
* The following table gives a rundown of the USB utilization of this demo.
*
* <table>
* <tr>
* <td><b>USB Mode:</b></td>
* <td>Device</td>
* </tr>

* </tr>
* </table>
*
* \section SSec_Description Project Description:
*
* This bootloader enumerates to the host as a HID Class device, allowing for device FLASH programming through
* the supplied command line software, which is a modified version of Paul's TeensyHID Command Line loader code
* from PJRC (used with permission). This bootloader is deliberately non-compatible with the proprietary PJRC
* HalfKay bootloader GUI; only the command line interface software accompanying this bootloader will work with it.
*
* Out of the box this bootloader builds for the AT90USB1287 with an 8KB bootloader section size, and will fit
* into 2KB of bootloader space for the Series 2 USB AVRs (ATMEGAxxU2, AT90USBxx2) or 4KB of bootloader space for
* all other models. If you wish to alter this size and/or change the AVR model, you will need to edit the MCU,
* FLASH_SIZE_KB and BOOT_SECTION_SIZE_KB values in the accompanying makefile.
*
* \warning <b>THIS BOOTLOADER IS NOT SECURE.</b> Malicious entities can recover written data, even if the device
* lockbits are set.
*
* \section Sec_Running Running the Bootloader
*
* This bootloader is designed to be started via the \c HWB mechanism of the USB AVRs; ground the \c HWB pin (see device
* datasheet) then momentarily ground \c /RESET to start the bootloader. This assumes the \c HWBE fuse is set and the
* \c BOOTRST fuse is cleared.
*
* \section Sec_Installation Driver Installation
*
* This bootloader uses the HID class driver inbuilt into all modern operating systems, thus no additional drivers
* need to be supplied for correct operation.
*
* \section Sec_HostApp Host Controller Application
*
* Due to licensing issues, the supplied bootloader is compatible with the HalfKay bootloader protocol designed
* by PJRC, but is <b>not compatible with the cross-platform loader GUI</b>. A modified version of the open source
* cross-platform TeensyLoader application is supplied, which can be compiled under most operating systems. The
* command-line loader application should remain compatible with genuine Teensy boards in addition to boards using
* this custom bootloader.
*
* Once compiled, programs can be loaded into the AVR's FLASH memory through the following example command:
* \code
* hid_bootloader_cli -mmcu=at90usb1287 Mouse.hex
* \endcode
*
* \section Sec_KnownIssues Known Issues:
*
* \par After loading an application, it is not run automatically on startup.
* Some USB AVR boards ship with the \c BOOTRST fuse set, causing the bootloader
* to run automatically when the device is reset. This booloader requires the
* \c BOOTRST be disabled and the HWBE fuse used instead to run the bootloader
* when needed.
*
* \section SSec_Options Project Options
*
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
*
* <table>
* <tr>
* <td>
* None
* </td>
* </tr>
* </table>

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

*
* \section Sec_Description Project Description:
*
* This bootloader enumerates to the host as a Mass Storage device, capable of reading and writing a new binary
* firmware image file, to load firmware onto the AVR.
*
* Out of the box this bootloader builds for the AT90USB1287 with an 8KB bootloader section size, and will fit
* into 6KB of bootloader space. If you wish to alter this size and/or change the AVR model, you will need to
* edit the MCU, FLASH_SIZE_KB and BOOT_SECTION_SIZE_KB values in the accompanying makefile.
*
* When the bootloader is running, the board's LED(s) will flash at regular intervals to distinguish the
* bootloader from the normal user application.
*
* \warning <b>THIS BOOTLOADER IS NOT SECURE.</b> Malicious entities can recover written data, even if the device
* lockbits are set.
*
* \section Sec_Running Running the Bootloader
*
* On the USB AVR8 devices, setting the \c HWBE device fuse will cause the bootloader to run if the \c HWB pin of
* the AVR is grounded when the device is reset.
*
* The are two behaviours of this bootloader, depending on the device's fuses:
*
* <b>If the device's BOOTRST fuse is set</b>, the bootloader will run any time the system is reset from
* the external reset pin, unless no valid user application has been loaded. To initiate the bootloader, the
* device's external reset pin should be grounded momentarily.
*
* <b>If the device's BOOTRST fuse is not set</b>, the bootloader will run only if initiated via a software
* jump, or if the \c HWB pin was low during the last device reset (if the \c HWBE fuse is set).
*
* For board specific exceptions to the above, see below.
*
* \subsection SSec_XPLAIN Atmel Xplain Board
* Ground the USB AVR JTAG's \c TCK pin to ground when powering on the board to start the bootloader. This assumes the
* \c HWBE fuse is cleared and the \c BOOTRST fuse is set as the HWBE pin is not user accessible on this board.
*
* \subsection SSec_Leonardo Arduino Leonardo Board
* Ground \c IO13 when powering the board to start the bootloader. This assumes the \c HWBE fuse is cleared and the
* \c BOOTRST fuse is set as the HWBE pin is not user accessible on this board.
*
* \section Sec_Installation Driver Installation
*
* This bootloader uses the Mass Storage drivers inbuilt into all modern operating systems, thus no additional
* drivers need to be supplied for correct operation.
*
* \section Sec_HostApp Host Controller Application
*
* This bootloader is compatible with all operating systems that support the FAT12 file system format. To reprogram the
* device, overwrite a file stored on the virtual FAT filesystem with a new binary (BIN format) image. Remember to safely
* remove your device from the host using the host OS's ejection APIs, to ensure all data is correctly flushed to the
* bootloader's virtual filesystem and not cached in the OS's file system driver.
*
* The current device firmware can be read from the device by reading a file from the virtual FAT filesystem. Two files will
* be present:
* - <b>FLASH.BIN</b>, representing the AVR's internal flash memory
* - <b>EEPROM.BIN</b>, representing the AVR's internal EEPROM memory
*
* To convert an existing Intel HEX (.HEX) program file to a binary (.BIN) file suitable for this bootloader, run:
* \code
* avr-objcopy -O binary -R .eeprom -R .fuse -R .lock -R .signature input.hex output.bin
* \endcode
* From a terminal, replacing <tt>input.hex</tt> and <tt>output.bin</tt> with the respective input and output filenames.
* AVR EEPROM data files in Intel HEX format (.EEP) uses a similar technique:
* \code
* avr-objcopy -O binary input.eep output.bin
* \endcode
*
* \warning This bootloader is currently <b>incompatible with the Apple MacOS X OS Finder GUI</b>, due to the
* large amount of meta files this OS attempts to write to the disk along with the new binaries. On
* this platform, firmwares must be copied to the disk via the Terminal application only to prevent
* firmware corruption.
*
* \section Sec_API User Application API
*
* Several user application functions for FLASH and other special memory area manipulations are exposed by the bootloader,
* allowing the user application to call into the bootloader at runtime to read and write FLASH data.
*
* By default, the bootloader API jump table is located 32 bytes from the end of the device's FLASH memory, and follows the
* following layout:
*
* \code
* #define BOOTLOADER_API_TABLE_SIZE 32
* #define BOOTLOADER_API_TABLE_START ((FLASHEND + 1UL) - BOOTLOADER_API_TABLE_SIZE)
* #define BOOTLOADER_API_CALL(Index) (void*)((BOOTLOADER_API_TABLE_START + (Index * 2)) / 2)
*
* void (*BootloaderAPI_ErasePage)(uint32_t Address) = BOOTLOADER_API_CALL(0);
* void (*BootloaderAPI_WritePage)(uint32_t Address) = BOOTLOADER_API_CALL(1);
* void (*BootloaderAPI_FillWord)(uint32_t Address, uint16_t Word) = BOOTLOADER_API_CALL(2);
* uint8_t (*BootloaderAPI_ReadSignature)(uint16_t Address) = BOOTLOADER_API_CALL(3);
* uint8_t (*BootloaderAPI_ReadFuse)(uint16_t Address) = BOOTLOADER_API_CALL(4);
* uint8_t (*BootloaderAPI_ReadLock)(void) = BOOTLOADER_API_CALL(5);
* void (*BootloaderAPI_WriteLock)(uint8_t LockBits) = BOOTLOADER_API_CALL(6);
*
* #define BOOTLOADER_MAGIC_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 2))
* #define BOOTLOADER_MAGIC_SIGNATURE 0xDCFB
*
* #define BOOTLOADER_CLASS_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 4))
* #define BOOTLOADER_MASS_STORAGE_SIGNATURE 0xDF30
*
* #define BOOTLOADER_ADDRESS_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 8))
* #define BOOTLOADER_ADDRESS_LENGTH 4
* \endcode
*
* From the application the API support of the bootloader can be detected by reading the FLASH memory bytes located at address
* \c BOOTLOADER_MAGIC_SIGNATURE_START and comparing them to the value \c BOOTLOADER_MAGIC_SIGNATURE. The class of bootloader
* can be determined by reading the FLASH memory bytes located at address \c BOOTLOADER_CLASS_SIGNATURE_START and comparing them
* to the value \c BOOTLOADER_MASS_STORAGE_SIGNATURE. The start address of the bootloader can be retrieved by reading the bytes
* of FLASH memory starting from address \c BOOTLOADER_ADDRESS_START.
*
* \subsection SSec_Aux_Space Auxiliary Bootloader Section
* To make the bootloader function on smaller devices (those with a physical bootloader section of smaller than 6KB) a second
* section of memory (called the <i>Auxiliary Bootloader Section</i>) is added before the start of the real bootloader section,
* and is filled with a portion of the bootloader code. This allows smaller devices to run the bootloader, at the cost of an
* additional portion of the device's FLASH (the bootloader section size in KB subtracted from the 6KB total size). A small
* trampoline is inserted at the start of the auxiliary section so that the bootloader will run normally in the case of a blank
* application section.
*
* On devices supporting a 8KB bootloader section size, the AUX section is not created in the final binary.
*
* \subsection SSec_API_MemLayout Device Memory Map
* The following illustration indicates the final memory map of the device when loaded with the bootloader.
*

*
* \section Sec_KnownIssues Known Issues:
*
* \par In some cases, the application is not fully loaded into the device.
* Write-caching on some operating systems may interfere with the normal
* operation of the bootloader. Write caching should be disabled when using the
* Mass Storage bootloader, or the file system synced via an appropriate command
* (such as the OS's normal disk ejection command) before disconnecting the device.
*
* \section Sec_Options Project Options
*
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
*
* <table>
* <tr>
* <th><b>Define Name:</b></th>
* <th><b>Location:</b></th>
* <th><b>Description:</b></th>
* </tr>

* \section Sec_Description Project Description:
*
* This bootloader enumerates to the host as a Generic Text Only Printer device, capable of reading and parsing
* "printed" plain-text Intel HEX files to load firmware onto the AVR.
*
* Out of the box this bootloader builds for the AT90USB1287 with an 8KB bootloader section size, and will fit
* into 4KB of bootloader space. If you wish to alter this size and/or change the AVR model, you will need to
* edit the MCU, FLASH_SIZE_KB and BOOT_SECTION_SIZE_KB values in the accompanying makefile.
*
* When the bootloader is running, the board's LED(s) will flash at regular intervals to distinguish the
* bootloader from the normal user application.
*
* \section Sec_Running Running the Bootloader
*
* On the USB AVR8 devices, setting the \c HWBE device fuse will cause the bootloader to run if the \c HWB pin of
* the AVR is grounded when the device is reset.
*
* The are two behaviours of this bootloader, depending on the device's fuses:
*
* <b>If the device's BOOTRST fuse is set</b>, the bootloader will run any time the system is reset from
* the external reset pin, unless no valid user application has been loaded. To initiate the bootloader, the
* device's external reset pin should be grounded momentarily.
*
* <b>If the device's BOOTRST fuse is not set</b>, the bootloader will run only if initiated via a software
* jump, or if the \c HWB pin was low during the last device reset (if the \c HWBE fuse is set).
*
* For board specific exceptions to the above, see below.
*
* \subsection SSec_XPLAIN Atmel Xplain Board
* Ground the USB AVR JTAG's \c TCK pin to ground when powering on the board to start the bootloader. This assumes the
* \c HWBE fuse is cleared and the \c BOOTRST fuse is set as the HWBE pin is not user accessible on this board.
*
* \subsection SSec_Leonardo Arduino Leonardo Board
* Ground \c IO13 when powering the board to start the bootloader. This assumes the \c HWBE fuse is cleared and the
* \c BOOTRST fuse is set as the HWBE pin is not user accessible on this board.
*
* \section Sec_Installation Driver Installation
*
* This bootloader uses the Generic Text-Only printer drivers inbuilt into all modern operating systems, thus no
* additional drivers need to be supplied for correct operation.
*
* \section Sec_HostApp Host Controller Application
*
* This bootloader is compatible with Notepad under Windows, and the command line \c lpr utility under Linux.
*
* \subsection SSec_Notepad Notepad (Windows)
*
* While most text applications under Windows will be compatible with the bootloader, the inbuilt Notepad utility
* is recommended as it will introduce minimal formatting changes to the output stream. To program with Notepad,
* open the target HEX file and print it to the Generic Text Only printer device the bootloader creates.
*
* \subsection SSec_LPR LPR (Linux)
*
* While the CUPS framework under Linux will enumerate the bootloader as a Generic Text-Only printer, many
* applications will refuse to print to the device due to the lack of rich formatting options available. As a result,
* under Linux HEX files must be printed via the low level \c lpr utility instead.
*
* \code
* cat Mouse.hex | lpr
* \endcode
*
* \section Sec_API User Application API
*
* Several user application functions for FLASH and other special memory area manipulations are exposed by the bootloader,
* allowing the user application to call into the bootloader at runtime to read and write FLASH data.
*
* By default, the bootloader API jump table is located 32 bytes from the end of the device's FLASH memory, and follows the
* following layout:
*
* \code
* #define BOOTLOADER_API_TABLE_SIZE 32
* #define BOOTLOADER_API_TABLE_START ((FLASHEND + 1UL) - BOOTLOADER_API_TABLE_SIZE)
* #define BOOTLOADER_API_CALL(Index) (void*)((BOOTLOADER_API_TABLE_START + (Index * 2)) / 2)
*
* void (*BootloaderAPI_ErasePage)(uint32_t Address) = BOOTLOADER_API_CALL(0);
* void (*BootloaderAPI_WritePage)(uint32_t Address) = BOOTLOADER_API_CALL(1);
* void (*BootloaderAPI_FillWord)(uint32_t Address, uint16_t Word) = BOOTLOADER_API_CALL(2);
* uint8_t (*BootloaderAPI_ReadSignature)(uint16_t Address) = BOOTLOADER_API_CALL(3);
* uint8_t (*BootloaderAPI_ReadFuse)(uint16_t Address) = BOOTLOADER_API_CALL(4);
* uint8_t (*BootloaderAPI_ReadLock)(void) = BOOTLOADER_API_CALL(5);
* void (*BootloaderAPI_WriteLock)(uint8_t LockBits) = BOOTLOADER_API_CALL(6);
*
* #define BOOTLOADER_MAGIC_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 2))
* #define BOOTLOADER_MAGIC_SIGNATURE 0xDCFB
*
* #define BOOTLOADER_CLASS_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 4))
* #define BOOTLOADER_PRINTER_SIGNATURE 0xDF20
*
* #define BOOTLOADER_ADDRESS_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 8))
* #define BOOTLOADER_ADDRESS_LENGTH 4
* \endcode
*
* From the application the API support of the bootloader can be detected by reading the FLASH memory bytes located at address
* \c BOOTLOADER_MAGIC_SIGNATURE_START and comparing them to the value \c BOOTLOADER_MAGIC_SIGNATURE. The class of bootloader
* can be determined by reading the FLASH memory bytes located at address \c BOOTLOADER_CLASS_SIGNATURE_START and comparing them
* to the value \c BOOTLOADER_PRINTER_SIGNATURE. The start address of the bootloader can be retrieved by reading the bytes of FLASH
* memory starting from address \c BOOTLOADER_ADDRESS_START.
*
* \subsection SSec_API_MemLayout Device Memory Map
* The following illustration indicates the final memory map of the device when loaded with the bootloader.
*
* \verbatim
* +----------------------------+ 0x0000
* | |
* | |
* | |
* | |
* | |

* +----------------------------+ FLASHEND - 8
* | Bootloader ID Constants |
* | (User App. Accessible) |
* +----------------------------+ FLASHEND
* \endverbatim
*
*
* \section Sec_KnownIssues Known Issues:
*
* \par On Linux machines, new firmware fails to be sent to the device via CUPS.
* Only a limited subset of normal printer functionality is exposed via the
* bootloader, causing CUPS to reject print requests from applications that
* are unable to handle true plain-text printing. For best results, the low
* level \c lpr command should be used to print new firmware to the bootloader.
*
* \section Sec_Options Project Options
*
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
*
* <table>
* <tr>
* <td>
* None

/** \mainpage Audio Input Device Demo
*
* \section Sec_Compat Demo Compatibility:
*
* The following list indicates what microcontrollers are compatible with this demo.
*
* \li Series 7 USB AVRs (AT90USBxxx7)
* \li Series 6 USB AVRs (AT90USBxxx6)
* \li Series 4 USB AVRs (ATMEGAxxU4)
*
* \section Sec_Info USB Information:
*
* The following table gives a rundown of the USB utilization of this demo.
*
* <table>
* <tr>
* <td><b>USB Mode:</b></td>
* <td>Device</td>
* </tr>
* <tr>
* <td><b>USB Class:</b></td>
* <td>Audio Class</td>
* </tr>
* <tr>
* <td><b>USB Subclass:</b></td>
* <td>Standard Audio Device</td>
* </tr>
* <tr>
* <td><b>Relevant Standards:</b></td>
* <td>USBIF Audio 1.0 Class Specification \n
* USBIF Audio 1.0 Class Terminal Types Specification \n
* USBIF Audio 1.0 Data Formats Specification</td>
* </tr>
* <tr>
* <td><b>Supported USB Speeds:</b></td>
* <td>Full Speed Mode</td>
* </tr>
* </table>
*
* \section Sec_Description Project Description:
*
* Audio demonstration application. This gives a simple reference
* application for implementing a USB Audio Input device using the
* basic USB Audio 1.0 drivers in all modern OSes (i.e. no special drivers
* required).
*
* On start-up the system will automatically enumerate and function as a
* USB microphone. By default, the demo will produce a square wave test tone
* when the board button is pressed. If USE_TEST_TONE is not defined in the
* project makefile, incoming audio from the ADC channel 1 will be sampled
* and sent to the host computer instead.
*
* When in microphone mode, connect a microphone to the ADC channel 2.
*
* Under Windows, if a driver request dialogue pops up, select the option
* to automatically install the appropriate drivers.
*
* \section Sec_Options Project Options
*
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
*
* <table>
* <tr>
* <th><b>Define Name:</b></th>
* <th><b>Location:</b></th>
* <th><b>Description:</b></th>
* </tr>
* <tr>
* <td>MIC_IN_ADC_CHANNEL</td>
* <td>AppConfig.h</td>
* <td>Sets the ADC channel used by the demo for the input audio samples from an attached microphone.</td>
* </tr>
* <tr>
* <td>USE_TEST_TONE</td>
* <td>AppConfig.h</td>
* <td>When defined, this alters the demo to produce a square wave test tone when the first board button is pressed
* instead of sampling the board microphone.</td>
* </tr>
* <tr>
* <td>MICROPHONE_BIASED_TO_HALF_RAIL</td>
* <td>AppConfig.h</td>
* <td>When defined, this alters the demo so that the half VCC bias of the microphone input is subtracted.</td>
* </tr>
* </table>
