`embedded-hal-async`

An asynchronous Hardware Abstraction Layer (HAL) for embedded systems.

This crate contains asynchronous versions of the embedded-hal traits and shares its scope and design goals.

This project is developed and maintained by the HAL team.

Serial/UART traits

There is no serial traits in embedded-hal-async. Instead, use embedded-io-async. A serial port is essentially a byte-oriented stream, and that's what embedded-io-async models. Sharing the traits with all byte streams has some advantages. For example, it allows generic code providing a command-line interface or a console to operate either on hardware serial ports or on virtual ones like Telnet or USB CDC-ACM.

Minimum Supported Rust Version (MSRV)

This crate requires Rust nightly newer than nightly-2022-11-22, due to requiring support for async fn in traits (AFIT), which is not stable yet.

Keep in mind Rust nightlies can make backwards-incompatible changes to unstable features at any time.
