Getting Started

Required dependencies

• cmake
• gcc-arm-embedded (for macOS)
• gcc-arm-none-eabi (for Linux)

Optional dependencies

• doxygen: For documentation generation
• clang-format: For formatting code

These dependencies can be install via Homebrew on macOS or apt on WSL.

Setup

1. Install the required dependencies
2. Run git submodule update --init from within lib/
3. Run git submodule update --init from within lib/pico-sdk/

Running

Build options

By default, FSW builds in LAUNCH mode. There are 2 build options you can set:

• VERBOSE: Displays state information over serial. FSW will only start running once a serial connection is made.
• SIM: FSW will execute a simulated flight path once the launch command is sent.

You can set these options in CMakeLists.txt. The executable name will change based on which build option(s) are set: fsw, fsw_verbose, fsw_sim, or fsw_sim_verbose.

Building

1. (First-time setup only) Create a top-level build/ directory
2. (First-time setup only) Run cmake .. from within build/
3. Set build options (see above)
4. Run make
5. Move the generated uf2 file to a Pico in boot select mode

You can also run make upload to automatically make and move the uf2 to a Pico in boot select mode
