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
2. flash `eeprom-lefthand.eep`/`eeprom-righthand.eep` to each half
* For boards with DFU bootloader you can use `:dfu-split-left`/`:dfu-split-right` to flash these EEPROM files
* For boards with Caterina bootloader (like stock Pro Micros), use `:avrdude-split-left`/`:avrdude-split-right`
* For boards with ARM DFU bootloader (like Proton C), use `:dfu-util-split-left`/`:dfu-util-split-right`
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
* For boards with ARM UF2 bootloader (like RP2040), use `:uf2-split-left`/`:uf2-split-right`
3. 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
#### Defines for handedness
* `#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 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.
* 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 eeprom to set side.
* `#define SPLIT_HAND_MATRIX_GRID <out_pin>,<in_pin>`
* The handedness is determined by using the intersection of the keyswitches in the key matrix, which does not exist. Normally, when this intersection is shorted (level low), it is considered right. If you define `#define SPLIT_HAND_MATRIX_GRID_LOW_IS_LEFT`, it is determined to be left when the level is low.
* `#define EE_HANDS` (only works if `SPLIT_HAND_PIN` and `SPLIT_HAND_MATRIX_GRID` are not defined)
* EEPROM (only works if `SPLIT_HAND_PIN` and `SPLIT_HAND_MATRIX_GRID` are 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
* `#define USE_I2C`
