PRU PID Motor Speed Controller Project at Github and Hackster.io

[Greg]

This project is based on a Texas Instruments demonstration project.

This project uses the RemoteProc and messaging framework to connect the PRUs to Linux user-space.
The PRU firmware code as published by TI was based on the "Mailboxes" which

was shortly thereafter changed to use the System interrupts.

A few minor changes were required to make the code compatible with the newer

RemoteProc system.

The project uses the PRUs to implement a "Proportional Integral Derivative" type DC motor speed controller.

In addition, a different Motor-encoder is recommended.  Minor tweaks were required

to the firmware code to match the specs of the different motor-encoder.
