What is it?

MicroZig is a toolbox for writing embedded firmware in the Zig programming language. It is aimed at developers who want to target microcontrollers using Zig's build system and language features, with a hardware abstraction layer (HAL) that sits between application code and the specific chip registers.

The project is organized around chip and board support packages, so a user can write application code against a common interface and select the target device at build time. The repository also documents its project layout in an architecture file for contributors.

The project is still in development, and its API is expected to change. The README pins the Zig version to 0.17.0, and readers should expect breaking changes between releases.

Key features

  • 01Hardware abstraction layer for microcontrollers written in Zig
  • 02Chip and board support packages selected at build time
  • 03Built on Zig's build system and language features
  • 04Includes architecture documentation for contributors

Use cases

  • Writing bare-metal firmware for microcontrollers in Zig
  • Porting an embedded application across different chip families through a shared HAL
  • Experimenting with Zig for embedded development

Quick start

  1. 1

    Install Zig version 0.17.0, the version the README specifies

  2. 2

    Go to microzig.tech to get started

Things to know

  • The project is in development and API breaks are expected.
  • It requires Zig 0.17.0 specifically.
