Using BeagleBone Blue to build an Autopilot Robot (part 1) – Circuit Cellar article

Hi folks! My name is Pedro Bertoleti and I’m a software engineer from Brazil. The October issue of Circuit Cellar’s magazine came out yesterday (9/18/2018), and I’ve written one of the articles of this issue (Title: “Building an Autopilot Robot (part 1)”, page 16). This article shows the groundwork for reliable  speed estimation based in […]

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 […]
