## What it is
MicroZig is a toolbox and framework for building embedded applications in Zig, extending the Zig build system to target specific microcontrollers. It generates memory-mapped IO bindings, linker scripts, and provides hardware abstraction layers for boards like the Raspberry Pi Pico.

## Use cases
- build embedded firmware in zig
- program raspberry pi pico with zig
- generate mmio register bindings from register descriptions
- cross-compile applications for microcontrollers
- write hardware abstraction layer code for custom boards
- blink an led on a microcontroller without writing c

## When to choose
- you want to write microcontroller firmware in Zig instead of C
- you need zero-cost abstractions over memory-mapped registers
- you want Zig's cross-compilation and C interop for embedded targets
- you're targeting Raspberry Pi Pico or other supported boards

## When to avoid
- you need a stable, production-ready API - the project is in development with breaking changes
- your microcontroller is not yet supported and you don't want to write your own register definitions
- you require a mature ecosystem with extensive driver support
- you're not comfortable tracking Zig master versions

## Facets
- artifact type: framework
- maturity: experimental
- function: embedded, build-tool, sdk, developer-tools
- domain: embedded-systems, developer-tools, hardware
- platform: embedded, cross-platform, cli
- tags: zig, hal, microcontrollers, mmio, raspberry-pi-pico, firmware, register-descriptions, linker-scripts
