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.
Optional Cargo features
defmt-03: Derivedefmt::Formatfromdefmt0.3 for enums and structs.
Minimum Supported Rust Version (MSRV)
This crate is guaranteed to compile on stable Rust 1.75 and up. It might compile with older versions but that may change in any new patch release.
See here for details on how the MSRV may be upgraded.
