## What it is
embedded-hal is a Rust Hardware Abstraction Layer providing core traits for embedded systems, enabling platform-agnostic device drivers. It includes blocking, async, and polling variants plus utilities for sharing SPI and I2C buses.

## Use cases
- write portable sensor drivers for microcontrollers in Rust
- abstract SPI and I2C bus access across platforms
- build embedded Rust applications that work on Cortex-M and AVR
- share an I2C bus between multiple device drivers
- use async traits for non-blocking embedded I/O

## When to avoid
- you need platform-specific functionality beyond the common traits embedded-hal provides
- you are not doing embedded development in Rust

## Facets
- artifact type: library
- maturity: stable
- function: embedded, sdk, plugin-system
- domain: embedded-systems, hardware, cross-platform
- platform: rust, embedded, iot
- tags: hardware-abstraction-layer, hal, traits, microcontrollers, drivers, async, no-std
