### Setting Handedness
One thing to remember, the side that the USB port is plugged into is always the master half. The side not plugged into USB is the slave.
There are a few different ways to set handedness for split keyboards (listed in order of precedence):
1. Set `SPLIT_HAND_PIN`: Reads a pin to determine handedness. If pin is high, it's the left side, if low, the half is determined to be the right side
2. Set `EE_HANDS` and flash `eeprom-lefthand.eep`/`eeprom-righthand.eep` to each half
3. Set `MASTER_RIGHT`: Half that is plugged into the USB port is determined to be the master and right half (inverse of the default)
4. Default: The side that is plugged into the USB port is the master half and is assumed to be the left half. The slave side is the right half
* `#define SPLIT_HAND_PIN B7` * `#define SPLIT_HAND_PIN B7`
* For using high/low pin to determine handedness, low = right hand, high = left hand. Replace 'B7' with the pin you are using. This is optional and you can still use the EEHANDS method or MASTER_LEFT / MASTER_RIGHT defines like the stock Let's Split uses. * For using high/low pin to determine handedness, low = right hand, high = left hand. Replace `B7` with the pin you are using. This is optional, and if you leave `SPLIT_HAND_PIN` undefined, then you can still use the EE_HANDS method or MASTER_LEFT / MASTER_RIGHT defines like the stock Let's Split uses.
* `#define EE_HANDS` (only works if `SPLIT_HAND_PIN` is not defined)
* Reads the handedness value stored in the EEPROM after `eeprom-lefthand.eep`/`eeprom-righthand.eep` has been flashed to their respective halves.
* `#define MASTER_RIGHT`
* Master half is defined to be the right half.
### Other Options

* If you want to specify a different pinout for the right half than the left half, you can define `MATRIX_ROW_PINS_RIGHT`/`MATRIX_COL_PINS_RIGHT`. Currently, the size of `MATRIX_ROW_PINS` must be the same as `MATRIX_ROW_PINS_RIGHT` and likewise for the definition of columns.
