Crate async_hal

Async hardware abstraction layer for embedded devices.

The easiest way to get started is to enable all features.

[dependencies]
async-hal = { version = "...", features = ["full"] }

Or by using cargo add

cargo add async-hal --features full

Feature flags

Async-hal uses a set of feature flags to reduce the amount of compiled code. It is possible to just enable certain features over others. By default, async-hal does not enable any features but allows one to enable a subset for their use case. Below is a list of the available feature flags. You may also notice above each function, struct and trait there is listed one or more feature flags that are required for that item to be used. If you are new to async-hal it is recommended that you use the full feature flag which will enable all public APIs. Beware though that this will pull in many extra dependencies that you may not need.

• full: Enables all features listed below except mock.
• executor: Enables the async_hal::executor module.
• nb: Enables async wrappers for non-blocking interfaces (such as from embedded_hal).
• bxcan: Enables CAN support for stm32 devices with bxcan.
