# Rust CP2130 Driver

A driver for the Silicon Labs [CP2130](https://www.silabs.com/interface/usb-bridges/classic/device.cp2130) USB->SPI bridge IC, exposing an [embedded-hal](https://github.com/rust-embedded/embedded-hal) compatible interface as well as a command line utility for interacting with (and testing interaction with) CP2130 devices.

## Status

WIP. Basic functionality working, PRs for extended features (non-volatile programming, alternate pin modes, etc.) are absolutely welcome.

## Getting started

You can install the utility with `cargo install driver-cp2130` or grab a pre-compiled release from [here]()

You may wish to copy [40-cp2130.rules](40-cp2130.rules) to `/etc/udev/rules.d` to allow all users with `plugdev` permissions to interact with the CP2130 device.
