I'm in the process of porting over the Google Chromium OS code into a standalone library for USB Power Delivery. I started with just the FUSB302-specific code. You find the github repo here. The example explains how to connect this breakout board to an Arduino. Then it reads the state of the CC pins, assuming it is plugged into a Downstream Facing Port.

The next major firmware upgrade will be a library that uses the FUSB302 library to send and receive PD messages and set states of the Type-C connector to perform all the higher-level functionality. Let me know if you are interested in helping out. Email me at or follow me on Twitter @AscendedDaniel.
