This is demonstration of custom USB_HID to make a mouse device that send absolute coordinate (as opposed to normal mouse that do relative move). This is working on Windows (and maybe other operating system, not tested yet).
- second hand uDraw Wii GameTablet (it talk I2C and connect like a Nunchuck
- Adafruit Wii Nunchuck Breakout Adapter - Qwiic / STEMMA QT => https://www.adafruit.com/product/4836
- Stemma QT cable
- Feather RP2040 (should work with many board that hav, but avoid M0 as this code need long int)
Install the following libraries:
- Adafruit_CircuitPython_HID: https://github.com/adafruit/Adafruit_CircuitPython_HID
- wiichuck: https://github.com/jfurcean/CircuitPython_WiiChuck (from the Community Bundle: https://github.com/adafruit/CircuitPython_Community_Bundle/releases/)
Copy the file mouse_abs.py from this repo to the CIRCUITPY drive in /lib/adafruit_hid
Copy the files boot.py and code.py on your CIRCUITPY drive

The uDraw specific part is my piece of code and contribution to CircuitPython_WiiChuck. Everything else has only been possible thanks to:
- @danh for all learn guide and the USB-HID code in the core of CircuitPython and in library
- @bitboy85 for providing working code for mouse_abs: https://gist.github.com/bitboy85/cdcd0e7e04082db414b5f1d23ab09005
