# ADNS9800
Add this module for controlling ADNS9800 optical sensor.
```python
from kmk.modules.adns9800 import ADNS9800
keyboard.modules.append(ADNS9800(cs=board.GP0, sclk=board.GP2, miso=board.GP4, mosi=board.GP3, invert_y=True))
```

Firmware for this sensor has to be obtained separately and placed in kmk\modules\adns9800_firmware.py
```python
firmware = (
    b'\x03'
    b'\xa6'
    ...
)
```

## Constructor parameters
ADNS9800(cs=*cs_pin*, sclk=*clock_pin*, miso=*miso_pin*, mosi=*mosi_pin*, invert_x=*False*, invert_y=*False*)
