sbence/pico-game-controller

Raspberry Pi Pico Firmware for a SDVX or IIDX controller setup. Supports 11 buttons, 10 LEDs, 1 WS2812B strip, and 2 encoders.

Pico-Game-Controller

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 v4, purchasable at https://discord.gg/MmuKd73XbY

About this fork

• Tested on and intended for Pocket SDVX Pico v5

• Based on SpeedyPotato's pocket-sdvx-pico-v5-develop branch

  • nomouse mode from 4yn's pocket-sdvx-pico-v5-develop-nomouse branch

Currently working/fixed

• Gamepad mode - default boot mode
• NKRO Keyboard & Mouse Mode - hold first button(gpio4) to enter kb mode
• HID LEDs with Reactive LED fallback
• ws2812b rgb on second core
• 2 ws2812b hid descriptor zones
• sdvx/iidx spoof - Tested on EAC - checkout branches release/pocket-sdvx-pico or release/pocket-iidx
• 1000hz polling
• Reversable Encoders with debouncing
• Switch debouncing
• Switch and LED pins are now staggered for easier wiring
• Fix 0-~71% encoder rollover in gamepad mode, uint32 max val isn't divisible evenly by ppr*4 for joystick - thanks friends
• HID LEDs now have labels, thanks CrazyRedMachine
• refactor ws2812b into a seperate file for cleaner code & implement more RGB modes (added turbocharger mode) - hold second button (gpio 6) to swap to turbocharger mode; hold 9th button (gpio 20) to turn off RGB
• refactor debouncing algorithms into separate files for cleaner code

TODO

• Store last mode in flash memory (probably implement into above TODO if possible) https://www.raspberrypi.org/forums/viewtopic.php?t=305570
• store configuration settings in a text file? consider implementing littlefs https://github.com/littlefs-project/littlefs https://www.raspberrypi.org/forums/viewtopic.php?t=313009 https://www.raspberrypi.org/forums/viewtopic.php?p=1894014#p1894014

Building the firmware

• Setup the C++ environment for the Pi Pico as per https://datasheets.raspberrypi.org/pico/getting-started-with-pico.pdf
• Build pico-examples directory once to ensure all the tinyusb and other libraries are there. You might have to move the pico-sdk folder into pico-examples/build for it to play nice.
• Move pico-sdk back outside to the same level directory as Pico-Game-Controller.
• Open Pico-Game-Controller in VSCode(assuming this is setup for the Pi Pico) and see if everything builds.
• Tweakable parameters are in controller_config.h
