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.
