joybus-pio rs

An implementation of the controller side of the joybus protocol for gamecube for the RP2040 chip via its PIO functionality.

joybus-pio and haybox were heavily referenced in the implementation.

Goals

Currently implemented

• Supports gamecube (joybus) controller protocol. (currently only tested on pc <-> gc adapter)

Things I would be happy for others to implement

• N64 support

Things I might be happy for others to implement

• Console side protocol support

Non-Goals

• Support for anything other than rp2040 PIO
  • If boards start using the RP2350 chip, or the RP2040 is in some other way seriously outdated I will consider moving to a new chip.

For understanding how the inner protocol works consider this excellent writeup on the GC controller protocol
