The logic analyzer software is written in Java and is open source. It is a fork of the original "Sump" software.
You do not want the original "Sump" software (now of historical interest only) written by Michael Poppitz. It may be of interest for other purposes, I don't really know. He did the development up to version 0.8, which was released 7-21-2007. His work stops then; I am not sure why or what he has gone on to do now.
