How to run C programs on the BeagleBone’s PRU microcontrollers

Tuesday, September 20th, 2016

Ken Shirriff writes: This article describes how to write C programs for the BeagleBone's microcontrollers. The BeagleBone Black is an inexpensive, credit-card sized computer that has two built-in microcontrollers called PRUs. By using the PRUs, you can implement real-time functionality that isn't possible in Linux. The PRU microcontrollers can be...

PRU tips: Understanding the BeagleBone’s built-in microcontrollers

Wednesday, September 7th, 2016

Ken Shirriff writes, "The BeagleBone Black is an inexpensive, credit-card sized computer that has two built-in microcontrollers called PRUs. While the PRUs provide the real-time processing capability lacking in Linux, using these processors has a learning curve. In this article, I show how to run a simple program on the...

19th century radio technology meets the Beaglebone

Monday, March 21st, 2016

Ashish Derhgawen built a coherer-based receiver with a simple decoherer mechanism, and connected it to a Beaglebone to decode the received signals: In my last post, I described how I made a spark-gap transmitter and receiver. For the transmitter, I used a car's ignition coil to produce high voltage sparks,...

SSD1306 and Python with the BeagleBone Black

Wednesday, February 5th, 2014

Ethan Zonca of Protofusion writes: The SSD1306 is an OLED display made with SPI and I2C interfaces. With a simple Python library I adapted (a modified version of py-gaugette), it is easy to render text, images (from bitmaps of pretty much any format), progress bars, etc. This guide is a...
