Dactyl Manuform 5x6 | |||
====== | |||
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. | |||
![Imgur](https://i.imgur.com/7y0Vbyd.jpg) | |||
## First Time Setup | |||
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: | |||
``` | |||
$ make handwired/dactyl_manuform/5x6:YOUR_KEYMAP_NAME | |||
``` | |||
If everything worked correctly you will see a file: | |||
``` | |||
dactyl_manuform_5x6_YOUR_KEYMAP_NAME.hex | |||
``` | |||
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 | |||
Currently there are only two keymaps: Qwerty and Dvorak, feel free to make changes and contribute your keymap. | |||
### Impstyle | |||
Required Hardware | |||
----------------- | |||
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 | |||
Optional Hardware | |||
----------------- | |||
A speaker can be hooked-up to either side to the `5` (`C6`) pin and `GND`, and turned on via `AUDIO_ENABLE`. | |||
Wiring | |||
------ | |||
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: | |||
![serial wiring](https://i.imgur.com/C3D1GAQ.png) | |||
The wiring for i2c: | |||
![i2c wiring](https://i.imgur.com/Hbzhc6E.png) | |||
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 | |||
------------------------------- | |||
the keymaps in here are for the 4x5 layout of the keyboard only. | |||
Flashing | |||
------- | |||
From the top level `qmk_firmware` directory run `make KEYBOARD:KEYMAP:avrdude` for automatic serial port resolution and flashing. | |||
Example: `make lets_split/rev2:default:avrdude` | |||
Choosing which board to plug the USB cable into (choosing Master) | |||
-------- | |||
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 | |||
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 | |||
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 | |||
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: | |||
``` | |||
avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-lefthand.eep | |||
// or the equivalent in dfu-programmer | |||
``` | |||
and similarly for right half | |||
``` | |||
avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-righhand.eep | |||
// or the equivalent in dfu-programmer | |||
``` | |||
NOTE: replace `$(COM_PORT)` with the port of your device (e.g. `/dev/ttyACM0`) | |||
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: | |||
``` | |||
// _delay_us(30); // without this wait read unstable value. | |||
_delay_us(300); // without this wait read unstable value. | |||
``` |
