FSFW Hardware Abstraction Layer
======

This repository contains hardware abstraction components for 
common hardware like `Raspberry Pi`s or the STM32H743ZIT6 board.

# Prerequisites

This library needs to be linked against the [Flight Software Framework](https://egit.irs.uni-stuttgart.de/fsfw/fsfw.git). Make sure that the library `fsfw` was added and linked against in your main application.

# Configuring the library with CMake options

There is a set of options available to compile the HAL.
These should be set by the upper level CMakeLists.txt, with 
`set(<Option> ON)`.

1. `FSFW_HAL_ADD_LINUX`: Add linux HAL. Requires `gpiod` library.
2. `FSFW_HAL_ADD_RASPBERRY_PI`: Add Raspberry Pi specific components.
3. `FSFW_HAL_ADD_STM32H7`: Add STM32H7 specific components.
