embedded-hal v1.0 now released!

The Rust Embedded Working Group is proud to announce the release of embedded-hal version 1.0 together with the companion crates embedded-hal-bus, embedded-hal-async and embedded-hal-nb.

Check out the repository, the API documentation and the migration guide.

The embedded-hal crates provide traits (interfaces) for using peripherals commonly available in microcontrollers such as GPIO, UART, SPI or I2C. They allow writing drivers (for sensors, displays, actuators, network adapters, etc.) in a generic way, so they work on any microcontroller with an embedded-hal implementation without modifying them. It's a central piece of the Embedded Rust ecosystem, ensuring interoperability throughout.

The 1.0 release has been in the works since 2020. Now that it's out, we consider all traits in it to be stable. The plan is to extend embedded-hal with more traits in future 1.x releases, not doing more breaking changes (i.e. there are no plans for a 2.0 release). This will provide a stable base for building HALs and drivers.

So, what's new in embedded-hal 1.0?

This Year in Embedded Rust: 2021

As 2021 draws to a close, we thought we'd take a look back at what's happened over the last year in Embedded Rust, both within the working group and in the larger community.
