The CPI range is 500-3500, in increments of 250. Defaults to 1000 CPI.
### PMW-3325 Sensor
To use the PMW-3325 sensor, add this to your `rules.mk`:
```make
POINTING_DEVICE_DRIVER = pmw3325
```
The following pins must be defined in `config.h`:
| Setting (`config.h`) | Description | Default |
| --------------------- | ------------------------------------------------------------------ | ---------------------------- |
| `PMW3325_CS_PIN` | (Required) The pin connected to the chip select pin of the sensor. | `POINTING_DEVICE_CS_PIN` |
| `PMW3325_SPI_DIVISOR` | (Required) The SPI clock divisor. This is dependent on your MCU. | _not defined_ |
The CPI range is 100-5000, in increments of 100. Defaults to 2000 CPI.
### PMW 3360 and PMW 3389 Sensor
This drivers supports both the PMW 3360 and PMW 3389 sensor as well as multiple sensors of the same type _per_ controller, so 2 can be attached at the same side for split keyboards (or unsplit keyboards).
