itsy-pac

Open source I-PAC-like using an Adafruit ItsyBitsy 32u4

Two-player arcade cabinet inputs using a single AdaFruit ItsyBitsy 32u4 (5V version recommended).

Features

Install arduino-cli and AdaFruit AVR core
Edit Config.h (the default keys follow MAME convention, but you may want to edit the shifted keys).
Ensure ItsyBitsy 32u4 is connected
Run ./build.sh
Run ./upload.sh

Written to be fast, not readable. Haven't measured latency much yet.

Borrows debouncing idea from Daemonbite. Uses N-key rollover implementation by Keyboardio Inc. and Nico Hood.
