Making a new device driver

To make your own libhal library:

1. press the green "Use this Template" button then
2. press the "Create a new repository".
3. Name it libhal-<insert_device_name> and replace <insert_device_name> with the name of the device's family. For exmaple, if you want to make a library for the MPU series of IMUs then call it libhal-mpu.
4. Choose where to put the repo under,
5. Go to settings > Pages > Build and deployment > Source and set the source to Github Actions.
6. Go to Pull Requests and merge the library rename pull request.
7. Done!

About the libhal-device template

The libhal-device repository is a template for creating device libraries in the libhal ecosystem. It provides a structured layout and a set of files to help you get started with creating your own device library.

.github/workflows

This directory contains GitHub Actions workflow files for continuous integration (CI) and other automated tasks. The workflows currently included are:

• ci.yml: This workflow runs the CI pipeline, which includes building the project, running tests, and deploying the library to the libhal-trunk package repository.
• take.yml: This workflow is responsible for the "take" action, which assigns commits to
• update_name.yml: This workflow updates the name of the repository when it's used as a template for a new repository.

conanfile.py

This is a Conan recipe file. Conan is a package manager for C and C++ that helps manage dependencies in your project. This file defines how Conan should build your project and its dependencies.

datasheets

This directory is intended for storing datasheets related to the device that the library is being built for. It currently contains a placeholder file, put_datasheets_here.md.

Many datasheets are subject to copyright and that must be considered when adding the datasheet to a libhal repo. If the datasheet cannot be redistributed on the repo for copyright and/or license reasons, then a markdown file with a link to the datasheet (and potentially mirrors of it) is an acceptable alternative.

demos

This directory contains demonstration applications showing how to use the device library. It includes:

• applications/__device__.cpp: A sample application demonstrating usage of the device library.
• hardware_map.hpp: A header file defining the hardware map for the demo applications.
• main.cpp: The main entry point for the demo applications.
• platforms/lpc4074.cpp and platforms/lpc4078.cpp: Platform-specific implementations for the demo applications.

include/libhal-device

This directory contains the header files for the device library. It currently includes __device__.hpp, which is a placeholder for the main header file of your device library.

src

This directory contains the source files for the device library. It currently includes __device__.cpp, which is a placeholder for the main source file of your device library.

test_package

This directory contains a test package for the Conan recipe. It includes a simple application that uses the device library, which helps verify that the Conan recipe is working correctly.

tests

This directory contains tests for the device library. It includes:

• __device__.test.cpp: A placeholder for tests for the device library.
• main.test.cpp: The main entry point for the tests.

Remember to replace all instances of __device__ with the actual name of the device that your library is being built for.
