Logitech Unifying Protocol Implementation

This project is an attempt to re-implement the proprietary Logitech Unifying protocol as a free and open C library.
The library is intended to be Arduino compatible while remaining compiler and hardware agnostic.
The goal of this project is to enable people to create custom keyboards and mice that are compatible with Logitech Unifying receivers.

Example

The provided Arduino example is dependent on the RF24 library.
