This is a collection of types that implement the embedded-hal traits.

The implementations never access real hardware. Instead, the hardware is mocked or no-op implementations are used.

The goal of the crate is to be able to test drivers in CI without having access to hardware.

Docs

See module-level docs for more information.

This crate supports both version 0.x and version 1.x of embedded-hal. By default only support for version 0.x is enabled. To enable support for version 1.x, use the eh1 feature.

There are currently the following cargo features:

• eh0: Provide module eh0 that mocks embedded-hal version 0.x
• eh1: Provide module eh1 that mocks embedded-hal version 1.x (enabled by default)
• embedded-time: Enable the eh0::timer module (enabled by default)
• embedded-hal-async: Provide mocks for embedded-hal-async in eh1

Currently this crate is not no_std. If you think this is important, let me know.

Pull requests for more mock implementations are welcome! :)

This crate is guaranteed to compile on the latest stable Rust release. It might compile with older versions but that may change in any new patch release.

If you would like to use the current development version of embedded-hal (or any other version), so long as they are API compatible you can use a patch field in your Cargo.toml file to override the dependency version.
