# Pico-Game-Controller
Code for a keyboard or game controller using a Raspberry Pi Pico. Capable of handling 11 buttons, 10 LEDs, 1 WS2812B RGB strip, and 2 encoders. Developed with SDVX and IIDX in mind - see branches release/pocket-sdvx-pico and release/pocket-iidx for preconfigured versions.
This branch was developed with IIDX in mind. Capable of handling 11 buttons, 11 LEDs, 1 WS2812B RGB strip, and 1 encoder. Note: 12 buttons/LEDs are reported but B8 should probably not be used (https://github.com/veroxzik/arduino-konami-spoof)
Demo of this firmware running on Pocket SDVX Pico, purchasable at https://discord.gg/MmuKd73XbY
