This is just a simple class used for talking to a Pixy with the Lego firmware installed on it. I have not fully tested it but it seems to work for the most part.
using information pulled from https://github.com/charmedlabs/pixy/blob/master/src/device/main_m4/src/serial.cpp
This has been minimally tested on the EV3 with Lejos 0.9.1 EV3
