This is a modification of the TMK firmware by ahtn found here https://github.com/ahtn/tmk_keyboard/tree/master/keyboard/split_keyboard
Custom split keyboard firmware
======
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
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_COL_PINS` and `MATRIX_ROW_PINS` in `config.h` accordingly.
The wiring for serial:
![serial wiring](imgs/split-keyboard-serial-schematic.png)
The wiring for i2c:
![i2c wiring](imgs/split-keyboard-i2c-schematic.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.
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
--------
Before you go to flash the program memory for the first time, you will need to
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.

also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
wire the lines to any other port, as long as D+ is also wired to INT0 (or any
other hardware interrupt, as long as it is the highest level interrupt, see
section at the end of this file).

* Possible properties are:
* + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
* at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
* used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if
* you want RAM pointers.
* + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
* in static memory is in RAM, not in flash memory.
* + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
* the driver must know the descriptor's length. The descriptor itself is
* found at the address of a well known identifier (see below).
* List of static descriptor names (must be declared PROGMEM if in flash):
* char usbDescriptorDevice[];
* char usbDescriptorConfiguration[];
* char usbDescriptorHidReport[];
* char usbDescriptorString0[];
* int usbDescriptorStringVendor[];
* int usbDescriptorStringDevice[];
* int usbDescriptorStringSerialNumber[];
* Other descriptors can't be provided statically, they must be provided
* dynamically at runtime.
*
* Descriptor properties are or-ed or added together, e.g.:
* #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
*
* The following descriptors are defined:
* USB_CFG_DESCR_PROPS_DEVICE
* USB_CFG_DESCR_PROPS_CONFIGURATION
