# driver-pal

A helper package for rust-embedded driver traits and implementations to assist with constructing drivers for embedded devices, currently focussed on SPI with the intent to extend this to support I2C in the future.
Previously known as `embedded-spi`, new releases at [crates.io/crates/driver-pal](https://crates.io/crates/driver-pal). 


This provides:

- a `CS` pin trait to communicate CS control for SPI based drivers
- a `Wrapper` type to provide this for an SPI and OutputPin implementation
- a `Hal` that abstracts over a number of SPI implementations to assist with writing driver utilities
- a `Mock` helper for testing drivers based on this
- a set of compatibility shims for c FFI use with dependency injected drivers

Currently patched-to-heck waiting on `embedded-hal` version `v1.0.0-alpha.3` with transactional SPI, and a bunch of
downstream patches that depend on this. You'll need to add the following patch line to any top-level project consuming this library:

```toml
[patch.crates-io]
embedded-hal = { git = "https://github.com/rust-embedded/embedded-hal.git", branch = "master" }
```
