Welcome to libhal

Abstract

libhal exists to make hardware drivers 🚚 portable, ðŸĶū flexible, ðŸ“Ķ accessible, and 🍰 easy to use. libhal seeks to provide a foundation for embedded drivers, allowing those drivers to be used across different processors, microcontrollers, systems, and devices.

The design philosophy of libhal is to be:

  1. Portable & Cross Platform
  2. Light Weight
  3. General
  4. Minimalist
  5. Safe & Reliable
  6. Tested & Testable
  7. Compiled Quickly
  8. OS Agnostic

The Basics

libhal, at its core, is simply a set of interfaces that correspond to hardware devices and peripherals. These interfaces use runtime polymorphism in order to decouple application logic from driver implementation details. This decoupling enables applications to run on any platform device that has the necessary components available.

A quick example is a blinker program. The required interfaces for such a program is a hal::output_pin for controlling the LED and a hal::steady_clock for keeping time. Now your application takes both of these drivers without having to consider their implementation details and blink and LED at a specified interval.
