Let's Split
|
||||||
|
======
|
||||||
|
|
||||||
|
This readme and most of the code are from https://github.com/ahtn/tmk_keyboard/
|
||||||
|
|
||||||
|
Split keyboard firmware for Arduino Pro Micro or other ATmega32u4
|
||||||
|
based boards.
|
||||||
|
|
||||||
|
Features
|
||||||
|
--------
|
||||||
|
|
||||||
|
Some features supported by the firmware:
|
||||||
|
|
||||||
|
* Either half can connect to the computer via USB, or both halves can be used
|
||||||
|
independently.
|
||||||
|
* You only need 3 wires to connect the two halves. Two for VCC and GND and one
|
||||||
|
for serial communication.
|
||||||
|
* Optional support for I2C connection between the two halves if for some
|
||||||
|
reason you require a faster connection between the two halves. Note this
|
||||||
|
requires an extra wire between halves and pull-up resistors on the data lines.
|
||||||
|
|
||||||
|
Required Hardware
|
||||||
|
-----------------
|
||||||
|
|
||||||
|
Apart from diodes and key switches for the keyboard matrix in each half, you
|
||||||
|
will need:
|
||||||
|
|
||||||
|
* 2 Arduino Pro Micro's. You can find theses on aliexpress for ≈3.50USD each.
|
||||||
|
* 2 TRS sockets
|
||||||
|
* 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 cable need to connect GND, VCC, and digital pin 3 (i.e.
|
||||||
|
PD0 on the ATmega32u4) between the two Pro Micros.
|
||||||
|
|
||||||
|
Then 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.
|
||||||
|
|
||||||
|
Notes on Software Configuration
|
||||||
|
-------------------------------
|
||||||
|
|
||||||
|
Configuring the firmware is similar to any other TMK project. One thing
|
||||||
|
to note is that `MATIX_ROWS` in `config.h` is the total number of rows between
|
||||||
|
the two halves, i.e. if your split keyboard has 4 rows in each half, then
|
||||||
|
`MATRIX_ROWS=8`.
|
||||||
|
|
||||||
|
Also the current implementation assumes a maximum of 8 columns, but it would
|
||||||
|
not be very difficult to adapt it to support more if required.
|
||||||
|
|
||||||
|
|
||||||
|
Flashing
|
||||||
|
--------
|
||||||
|
|
||||||
|
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:
|
||||||
|
```
|
||||||
|
make eeprom-left
|
||||||
|
```
|
||||||
|
and similarly for right half
|
||||||
|
```
|
||||||
|
make eeprom-right
|
||||||
|
```
|
||||||
|
|
||||||
|
After you have flashed the EEPROM for the first time, you then need to program
|
||||||
|
the flash memory:
|
||||||
|
```
|
||||||
|
make program
|
||||||
|
```
|
||||||
|
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. 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.
