I'm looking to create an arcade stick with arduino programmed microcontrollers, namely a Teensy 2.0, and a Chinese ARM32 STM board. I haven't even begun work on my ARM32 board yet but I already have a functional arcade stick that works with the teensy 2.0 board.
Has anyone discovered how to code a functional home button for playstation on one of these boards in arduino? I've seen people talk about this giant hex file that works but I don't know how to use it.
