Dependencies

This project uses CMake, as well as a working ARM toolchain.

Ensure you have the following installed before proceeding:

• Git
• CMake with version 3.27 or higher
• A working ARM GCC compiler
• The ARM newlib library for the installed ARM GCC compiler

On Arch Linux, this corresponds to the git, cmake, arm-none-eabi-gcc, and arm-none-eabi-newlib packages.

On other platforms, see the official Pico SDK documentation for instructions on preparing a build environment.

Setup

Before building the project, it is required to initialise the submodules.

To do this, simply run the following git command in the repository root.

git submodule update --init --recursive

After having successfully initialised the submodules, the project is ready for building.

Build

To generate the files needed to start a build, run the following command.

cmake -B build

These generated files can then be used to build the project.

cmake --build build -j16

Finally, flash the PI PICO by mounting it in BOOTSEL mode and copying the file located at build/main.uf2.
