The size of the `matrix_pins.cols` and `matrix_pins.rows` arrays infer the size of the matrix (previously `MATRIX_ROWS` and `MATRIX_COLS`).
## Configuration Options
To invert the keypress logic, configure `input_pressed_state`:
```json
"matrix_pins": {
"input_pressed_state": 1,
},
```
This configures state of the GPIO pins when the key is pressed - `1` for high, `0` for low. Default value is `0`.
Finally, you can specify the direction your diodes point. This can be `COL2ROW` or `ROW2COL`.
```json
