STD_TYPES, MCU_UART, MCU_USB, MCU_PIO, HAL_COM, HAL_LED moved to separate repos under common/ as git submodules. Each submodule ships with default config (cfg/) that projects can override. color_switcher/src/ now contains only project-specific components (APP_CLSW, SYS_ECU). CMake sources_config references common/ via COMMON_DIR. Docker volume mounts ../common:/common so the container sees the submodules. Build verified — zero errors.
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.
