I’ve been trying to find a simple way of making arduboy button presses convert to CPU button input(I’m trying to make a game controller)
To work as a mouse or keyboard, you can use the Arduino mouse and keyboard libraries. @fuopy has made a sketch that you can use as an example.
To work as a joystick, there is a joystick library written by Matthew Heironimus. @eried has made a sketch that uses this library, which you can use as an example
I wasn’t sure if they were over complicated or just hard (keyboard)
