CGI using C++ on the BeagleBone (Ggicc)

In Chapter 10 of my book (pg. 388-393), Exploring BeagleBone, I describe how you can build web-based CGI applications that can interface with electronics hardware that is attached to the BeagleBone using Bash scripts that call C/C++ programs. The solution works well for very straightforward applications, but this discussion investigates more advanced solutions for applications where there are more complex interactions — for example, […]

Driving LED Arrays

I have started to investigate how I can drive a large bank of LEDs directly from my Beaglebone or Raspberry PI. I have developed a video before:

where I drove a 2 colour 8×8 LED common anode dot matrix display using three 74HC595s and a transistor array UDN2981A to source the current. This used the Arduino as the platform to drive […]
