Pico Projects

A collection of Raspberry Pi Pico (RP2040) firmware projects. Each project is self-contained in its own subfolder with its own Dockerized build system, CMake configuration, and source code.

Projects

Project	Description	Target Board
color_switcher	Interactive color-switching firmware with USB-CDC serial commands and WS2812B LED control via PIO	Waveshare RP2040-Zero

Getting Started

Each project is independent. To work on one, cd into its folder:

cd color_switcher/
docker compose build              # first time only
docker compose run --rm pico-build bash build.sh   # compile
./flash.sh                        # flash to Pico (hold BOOTSEL + plug in)

See each project's own README.md for project-specific instructions.

Prerequisites

• Docker and Docker Compose

No local ARM toolchain needed — everything builds inside Docker containers.
