A digital guitar pedal project by Linus Torvalds built around an RP2354A microcontroller and a TI audio codec, with seventeen software-defined effects running on a dedicated core. The repo contains KiCad hardware files, DSP and effect code, embedded firmware, a browser-based WebMIDI editor, and a validation test suite.
Use cases
- build a DIY digital guitar effects pedal
- run audio effects like biquad filters and LFOs on a microcontroller
- edit pedal effects from a browser over USB MIDI
- learn analog and embedded audio circuit design
- test DSP effect code on a host machine before flashing firmware
- customize guitar pedal firmware for RP2040/RP2350 hardware
When to choose
- you want to build or modify an open-source digital guitar pedal
- you need a reference design combining pico-sdk, tinyusb, and real-time audio DSP
- you want host-testable effect code shared between firmware and a web editor
When to avoid
- you need a polished consumer product with a friendly on-device UI
- you want a general-purpose audio plugin or DAW effect rather than standalone hardware
- you need extensive documentation - the docs are sparse
- you only build on non-Linux platforms without willingness to sort out toolchain requirements yourself
