# 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 SDVX in mind. Capable of handling 7 LEDs, 1 WS2812B RGB strip, and 2 encoders.
Demo of this firmware running on Pocket SDVX Pico, purchasable at https://discord.gg/MmuKd73XbY

Quick how-to flash:
1. Hold down Pi Pico button when plugging it in.
If you haven't already, download Pico_Game_Controller.uf2 first by clicking it above and then clicking the Download button near the top right.
1. Hold down Pi Pico button when plugging it in. (This is the button on the bottom of the controller)
2. Drag Pico_Game_Controller.uf2 into the 'drive' RPI-RP2
3. Done!
