The HSA Logic is a USB-based, 8-channel logic analyzer with 6.25 MHz sampling rate. It is an open-hardware / open-source design. Both hardware and software have been developed at Hochschule Augsburg so far. Everything started with this bachelor thesis in 2010. It was continued in 2013/14 as semester project.
