Multi-channel communication abstraction where each channel is wired to an MCU driver via function pointers in the config array. Adding a new transport (SPI, I2C, etc.) requires only a config entry — zero changes to HAL_COM_prg.c. Channel 0 defaults to USB-CDC via thin wrappers that normalize MCU_USB's signature. HAL_COM.h includes HAL_COM_cfg.h so callers can reference channel names. APP_CLSW updated to pass channel parameter.
Color Switcher
A Raspberry Pi Pico project that sends commands over UART to a connected computer. Written entirely in C using the Pico SDK.
Prerequisites
- Docker and Docker Compose
No local toolchain installation needed — everything runs inside the container.
Building
# Build the Docker image (first time only, or after Dockerfile changes)
docker compose build
# Compile the firmware
docker compose up
The .uf2 firmware file will appear in build/.
Flashing
- Hold the BOOTSEL button on the Pico and plug it into USB
- It mounts as a USB mass storage device
- Drag the
.uf2file frombuild/onto the Pico - The Pico reboots and runs the firmware
Interactive Shell
To drop into the build container for debugging or manual commands:
docker compose run --rm pico-build bash
