AGENTS

Project type: Arduino library that can be compiled for Linux and the Pico SDK.

Building docs

requires: doxygen

steps:

• cd docs
• doxygen (generates docs/html)
• optional: open docs/html/index.html

Build library

requires: cmake, build tools (and sudo for install)

steps:

• cmake -B build -S . [...cmake options]
• cmake --build build
• sudo cmake --install build (required for building examples)

Build environment & dependency ordering

• Dependency ordering (use git HEAD of master unless specified):
  1. [RF24] (build & install)
  2. [RF24Network] (build & install)
  3. RF24Mesh (build)
• Example commands to install dependencies from source (repeat for each dependency):
  • git clone <repo> && cd <repo>
  • cmake -B build -S .
  • cmake --build build
  • sudo cmake --install build

Examples (RPi/Linux)

requires: cmake, build tools

steps:

• cmake -B examples_RPi/build examples_RPi [...cmake options]
• cmake --build examples_RPi/build

Pico SDK examples

requires: cmake, [PicoSDK] (Windows: ninja may be required)

steps:

• cmake -B examples_pico/build examples_pico [...cmake opts]
• cmake --build examples_pico/build

About RF24 and RF24Network dependency

The examples_pico/CMakeLists.txt expects RF24 and RF24Network repos checked out adjacent to this repo's root folder. Unless otherwise noted, RF24 and RF24Network master branch tip is used.

Install Python wrapper

requires:

• python, pip, and Python C API headers
• boost.python (typically provided via apt-get install)

steps:

• Create a venv (can be done with various tools). Need only be done once.
• Activate the venv (depends on method used in previous step), if not already in active venv.
• pip install -v ./pyRF24Mesh

Notes about dependencies:

• Most dependencies can be installed via apt-get install python3-dev libboost-python-dev.
• The RF24 and [RF24Network] (C++ libs) are required to be installed beforehand too.

Format sources

requires: clang-format v14.x

steps:

• clang-format-14 -i --style=file <file>
• On Windows (powershell does not expand globs): clang-format -i --style=file <file>

Clang-tidy notes

Note: clang-tidy can only be used when targeting Linux builds. Prefer WSL when building on a Windows host machine.

• To generate a compilation database required by clang-tidy:
  • cmake -B build -S . -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
• Run clang-tidy with the -p option pointing to the build directory:
  • clang-tidy -p build <files>
