BeagleBone Black: TI eQEP demo with rotary encoder

Video: https://www.youtube.com/watch?v=4qvnOxG8vko

I demonstrate how to read position of a rotary encoder connected to the BeagleBone Black.  I use the eQEP (enhanced Quadrature-Encoded Pulse) decoder module built-in to the BBB's TI Sitara ARM processor.

NOTE: This requires the TI eQEP Linux kernel module from Nathiel Lewis (http://nathanielrlewis.com/?p=87) which is inlcuded on BeagleBoard.org Debian image for BBB since 2014-May-14 (http://beagleboard.org/latest-images)

Further information on the eQEP kernel module and API for Python & C++ is in Nathaniel's GitHub repo: https://github.com/Teknoman117/beaglebot/tree/master/encoders
