Dactyl Manuform (4x5, 5x6, 5x7, 6x6, 6x7)
2018-08-14 17:54:22 +00:00
======
the [Dactyl-Manuform ](https://github.com/tshort/dactyl-keyboard ) is a split curved keyboard based on the design of [adereth dactyl ](https://github.com/adereth/dactyl-keyboard ) and thumb cluster design of the [manuform ](https://geekhack.org/index.php?topic=46015.0 ) keyboard, the hardware is similar to the let's split keyboard. all information needed for making one is in the first link.
## First Time Setup
2018-08-23 18:48:30 +00:00
2018-08-14 17:54:22 +00:00
Download or clone the `qmk_firmware` repo and navigate to its top level directory. Once your build environment is setup, you'll be able to generate the default .hex using:
2018-08-15 22:31:59 +00:00
Depending on your Layout chose one of the follwing commands:
2018-08-14 17:54:22 +00:00
```
2018-08-15 22:31:59 +00:00
$ make handwired/dactyl_manuform/YOUR_LAYOUT:YOUR_KEYMAP_NAME
```
example:
```
$ make handwired/dactyl_manuform/4x5:default
2018-08-14 17:54:22 +00:00
```
If everything worked correctly you will see a file:
```
2018-08-15 22:31:59 +00:00
dactyl_manuform_YOUR_LAYOUT_YOUR_KEYMAP_NAME.hex
2018-08-14 17:54:22 +00:00
```
For more information on customizing keymaps, take a look at the primary documentation for [Customizing Your Keymap ](/docs/faq_keymap.md ) in the main readme.md.

### [Keymaps 5x6_5](/keyboards/handwired/dactyl_manuform/5x6_5/keymaps/)
Similar layout to 5x6 but with only 5 thumb keys per side instead of 6.

#### Via
Similar to Default but adds support for the [Via ](https://www.caniusevia.com/ ) keymap configurator. Reduces the number of layers to 4 to comply with Via defaults, and remaps
some keys to accomodate that constraint.

## Required Hardware
2018-08-14 17:54:22 +00:00
Apart from diodes and key switches for the keyboard matrix in each half, you
will need:
* 2 Arduino Pro Micros. You can find these on AliExpress for ≈3.50USD each.
* 2 TRRS sockets and 1 TRRS cable, or 2 TRS sockets and 1 TRS cable
Alternatively, you can use any sort of cable and socket that has at least 3
wires. If you want to use I2C to communicate between halves, you will need a
cable with at least 4 wires and 2x 4.7kΩ pull-up resistors
2018-08-23 18:48:30 +00:00
## Optional Hardware
2018-08-14 17:54:22 +00:00
A speaker can be hooked-up to either side to the `5` (`C6`) pin and `GND` , and turned on via `AUDIO_ENABLE` .
2018-08-23 18:48:30 +00:00
## Wiring
2018-08-14 17:54:22 +00:00
The 3 wires of the TRS/TRRS cable need to connect GND, VCC, and digital pin 3 (i.e.
PD0 on the ATmega32u4) between the two Pro Micros.
Next, wire your key matrix to any of the remaining 17 IO pins of the pro micro
and modify the `matrix.c` accordingly.
The wiring for serial:
The wiring for i2c:
The pull-up resistors may be placed on either half. It is also possible
to use 4 resistors and have the pull-ups in both halves, but this is
unnecessary in simple use cases.
You can change your configuration between serial and i2c by modifying your `config.h` file.

## Notes on Software Configuration
2018-08-14 17:54:22 +00:00
the keymaps in here are for the 4x5 layout of the keyboard only.
2018-08-23 18:48:30 +00:00
## Flashing
2018-08-15 22:31:59 +00:00
To flash your firmware take a look at: [Flashing Instructions and Bootloader Information ](https://docs.qmk.fm/#/flashing )
2018-08-14 17:54:22 +00:00
2018-08-23 18:48:30 +00:00
## Choosing which board to plug the USB cable into (choosing Master)
2018-08-14 17:54:22 +00:00
Because the two boards are identical, the firmware has logic to differentiate the left and right board.
It uses two strategies to figure things out: looking at the EEPROM (memory on the chip) or looking if the current board has the usb cable.
The EEPROM approach requires additional setup (flashing the eeprom) but allows you to swap the usb cable to either side.
The USB cable approach is easier to setup and if you just want the usb cable on the left board, you do not need to do anything extra.
### Setting the left hand as master
2018-08-23 18:48:30 +00:00
2018-08-14 17:54:22 +00:00
If you always plug the usb cable into the left board, nothing extra is needed as this is the default. Comment out `EE_HANDS` and comment out `I2C_MASTER_RIGHT` or `MASTER_RIGHT` if for some reason it was set.
### Setting the right hand as master
2018-08-23 18:48:30 +00:00
2018-08-14 17:54:22 +00:00
If you always plug the usb cable into the right board, add an extra flag to your `config.h`
```
#define MASTER_RIGHT
```
### Setting EE_hands to use either hands as master
2018-08-23 18:48:30 +00:00
2018-08-14 17:54:22 +00:00
If you define `EE_HANDS` in your `config.h` , you will need to set the
EEPROM for the left and right halves.
The EEPROM is used to store whether the
half is left handed or right handed. This makes it so that the same firmware
file will run on both hands instead of having to flash left and right handed
versions of the firmware to each half. To flash the EEPROM file for the left
half run:
```
2019-02-18 16:49:11 +00:00
make handwired/dactyl_promicro:default:dfu-split-left
make handwired/dactyl_promicro:default:dfu-split-right
2018-08-14 17:54:22 +00:00
```
After you have flashed the EEPROM, you then need to set `EE_HANDS` in your config.h, rebuild the hex files and reflash.
Note that you need to program both halves, but you have the option of using
different keymaps for each half. You could program the left half with a QWERTY
layout and the right half with a Colemak layout using bootmagic's default layout option.
Then if you connect the left half to a computer by USB the keyboard will use QWERTY and Colemak when the
right half is connected.
Notes on Using Pro Micro 3.3V
-----------------------------
Do update the `F_CPU` parameter in `rules.mk` to `8000000` which reflects
the frequency on the 3.3V board.
Also, if the slave board is producing weird characters in certain columns,
update the following line in `matrix.c` to the following:
```
2019-02-18 16:49:11 +00:00
// wait_us(30); // without this wait read unstable value.
wait_us(300); // without this wait read unstable value.
2018-08-14 17:54:22 +00:00
```
