@defgroup pfleury_ic2master I2C Master library
@code #include <i2cmaster.h> @endcode
@brief I2C (TWI) Master Software Library
Basic routines for communicating with I2C slave devices. This single master
implementation is limited to one bus master on the I2C bus.
This I2c library is implemented as a compact assembler software implementation of the I2C protocol
which runs on any AVR (i2cmaster.S) and as a TWI hardware interface for all AVR with built-in TWI hardware (twimaster.c).
Since the API for these two implementations is exactly the same, an application can be linked either against the
software I2C implementation or the hardware I2C implementation.
Use 4.7k pull-up resistor on the SDA and SCL pin.
Adapt the SCL and SDA port and pin definitions and eventually the delay routine in the module
i2cmaster.S to your target when using the software I2C implementation !
Adjust the CPU clock frequence F_CPU in twimaster.c or in the Makfile when using the TWI hardware implementaion.
@note
The module i2cmaster.S is based on the Atmel Application Note AVR300, corrected and adapted
to GNU assembler and AVR-GCC C call interface.
Replaced the incorrect quarter period delays found in AVR300 with
half period delays.
@author Peter Fleury pfleury@gmx.ch http://jump.to/fleury
@par API Usage Example
The following code shows typical usage of this library, see example test_i2cmaster.c
@code
#include <i2cmaster.h>
#define Dev24C02 0xA2 // device address of EEPROM 24C02, see datasheet
int main(void)
{
unsigned char ret;
i2c_init(); // initialize I2C library
// write 0x75 to EEPROM address 5 (Byte Write)
i2c_start_wait(Dev24C02+I2C_WRITE); // set device address and write mode
i2c_write(0x05); // write address = 5
i2c_write(0x75); // write value 0x75 to EEPROM
i2c_stop(); // set stop conditon = release bus
// read previously written value back from EEPROM address 5
i2c_start_wait(Dev24C02+I2C_WRITE); // set device address and write mode
i2c_write(0x05); // write address = 5
i2c_rep_start(Dev24C02+I2C_READ); // set device address and read mode
ret = i2c_readNak(); // read one byte from EEPROM
i2c_stop();

# [Gergo! By g Heavy Industries](http://gboards.ca)
![Gergo image](https://4.bp.blogspot.com/-889nMXxgSM0/XCNxwnO5kUI/AAAAAAAA6mI/tZbWgZVCBW0dyZOCGJDkjN06DVax7j8XwCLcBGAs/s1600/48422820_967732713413298_485744639215665152_n.jpg)
This is the default keymap for Gergo, it's based heavily off of the naps62 ErgoDox layout and is aimed at a programmer friendly keymap.
## Settings
To edit various settings, enable the 1u trackball and whatnot please modify /keyboards/gergo/keymaps/default/rules.mk
Ideally you should copy this directory and make your changes there. If you come up with a good layout submit a PR!

# Gergo
![Gergo](https://cdn.pbrd.co/images/HVglSWD.jpg)
A compact 50% (14x4) Split Keyboard compatible with i2c modules and a trackball.
[More info on qmk.fm](http://qmk.fm/gergo/)
Keyboard Maintainer: [Jeremy Bernhardt](https://github.com/germ)
Hardware Supported: Gergo (Kit, Partial, Ready)
Hardware Availability: [gboards.ca](http://gboards.ca)
## Firmware building
After cloning the QMK repo and installing dfu-programmer build and flash with. Be sure to reset your keyboard!
make gergo:germ:dfu
To just test your build with the default keymap
make gergo:germ
Gadgets and options can be enabled/disabled in keyboards/gergo/keymaps/default/rules.mk . Copy the default directory and make any changes to your layout, if you think they're worth sharing submit a PR!
See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
