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).

For both players:

  • Up, Down, Left, Right
  • Buttons 1-6
  • Start

Only one coin button is mapped (P1) because I ran out of GPIOs on the ItsyBitsy.

Written to be fast, not readable. Haven’t measured latency much yet. Borrows debouncing idea from Daemonbite.
