In the book ‘Exploring Beaglebone’ by Derek Molloy, he used a Digilent Analog Discovery tool to show oscilloscope waveforms. This tool is a two-channel digital oscilloscope, a 16-channel logic analyser, waveform generator and power supply, all connected to a PC using a USB cable. It appears to offer the best value for money. It cost $279 plus $58 delivery – $338 in total, or about £210.
The Analog Discovery comes with female connectors. For this reason, I have added a two-pin male connector to my LED board.This connector allows me to connect the Analog Discovery directly to the board.
