Raspberry Pi Pico Lab

Template and Examples in C/C++ for the Raspberry Pi Pico using the official SDK, via Docker.

• The official SDK is cloned into the Docker image, see Dockerfile for details
• Check out the examples in src/
• Utilize existing code for an own project or start with a basic example
• Having Docker in place, the projects can be built with a single command

Features

Feature	Example	Info	Tested on boards
blink	src/main_blink.c	Hello world blink example	pico, pico_w
debounce	src/main_debounce.c	Button debouncer	pico, pico_w
ws2812	src/main_ws2812.c	Basic ws2812 light controls	pico, pico_w

Kick-start

A Docker installation and basic Docker knowledge is required.

1. Build the Docker image:

docker build -t rpico .

2. Build the examples via Docker with one of these commands. Replace <pico_board> with the desired board to build for, such as pico or pico_w.

# Bash
docker run --rm -v $(pwd):/code -w /code rpico /bin/bash ./build.bash <pico_board>

# Powershell
docker run --rm -v ${PWD}:/code -w /code rpico /bin/bash ./build.bash <pico_board>

3. Drop any UF2 binary from build_<pico_board>/ directory onto the Pico following the official documentation.

Advanced usage

The above should suffice for simple building of the examples. Here are some more things to do.

Use this repository as a template for an own project:

• Fork or download this repository
• Delete unneeded source files from src/
  • e.g. just keep main_blink.c to start with
• Delete unneeded build targets from CMakeLists.txt
  • Each main_[...].c/.cpp file in src/ has a corresponding block in CMakeLists.txt defining an executable target
  • e.g. just keep the block starting with add_executable(blink ...

More control over the build command:

# Bash
docker run --rm -v $(pwd):/code -w /code rpico /bin/bash -c "mkdir -p build && cd build && cmake -DPICO_BOARD=pico .. && make"

# Powershell
docker run --rm -v ${PWD}:/code -w /code rpico /bin/bash -c "mkdir -p build && cd build && cmake -DPICO_BOARD=pico .. && make"

Start Docker container with an interactive shell:

# Bash
docker run --rm -it -v $(pwd):/code rpico

# Powershell
docker run --rm -it -v ${PWD}:/code rpico
