Motor Speed Control using BeagleBone PRU

Motor Speed Control using BeagleBone PRU

Greg Raven created this motor speed controller based on a Texas Instruments demonstration project.  His implementation uses RemoteProc and RPMsg framework to connect the PRUs (Programmable Real-time Units) to Linux userspace.  The PRUs are 32-bit RISC processors which offload real-time tasks from Linux running on the ARM processor. The system implements a Proportional Integral Derivative (PID) controller. The controlled […]
