Arduino A2 Encoder / SEI Bus Library

Webpage and wiki under construction, but the code works!

Updated 2019-09-08

This library interfaces an Arduino to an US Digital SEI Bus to communicate with A2 absolute encoders.  The protocol works with the A2, A2T, A4, HBA2, HBA4, and HD25A products.

Code and documentation wiki are located on GitHub.
