## Driver crates
Platform agnostic crates to interface external components. These crates use the [`embedded-hal`]
interface to support [all the devices and systems that implement the `embedded-hal`
traits][hal-impl].
[hal-impl]: #hal-implementation-crates
The list below contains drivers that have achieved the "released" status. To add a driver
to this list, please ensure that your driver has a short blog post, article, or sufficiently
explanatory README showing an example of its use. Ideally, this post would demonstrate using the
device in a small project so that a Rust and/or embedded newcomer can also understand it.
Otherwise, please add it to the [WIP section](#WIP) below.
