## Split Keyboards
If you are using different pinouts for the encoders on each half of a split keyboard, you can define the pinout (and optionally, resolutions) for the right half like this:
The above is enough for split keyboards that are symmetrical, i.e. the halves have the same number of encoders and they are on the same pins.
If the halves are not symmetrical, you can define the pinout (and optionally, resolutions) of the right half separately.
The left half will use the definitions above.
```c
#define ENCODERS_PAD_A_RIGHT { encoder1a, encoder2a }
@ -54,6 +56,17 @@ If you are using different pinouts for the encoders on each half of a split keyb
#define ENCODER_RESOLUTIONS_RIGHT { 2, 4 }
```
If only the right half has encoders, you must still define an empty array for the left pads (and resolutions, if you define `ENCODER_RESOLUTIONS_RIGHT`).
```c
#define ENCODERS_PAD_A { }
#define ENCODERS_PAD_B { }
#define ENCODER_RESOLUTIONS { }
#define ENCODERS_PAD_A_RIGHT { encoder1a, encoder2a }
#define ENCODERS_PAD_B_RIGHT { encoder1b, encoder2b }
#define ENCODER_RESOLUTIONS_RIGHT { 2, 4 }
```
## Callbacks
The callback functions can be inserted into your `<keyboard>.c`:
