"A connection" means that there are at least two ends, in this case your controller and the PC. For which part do you require information? If it's only for the PC, what is the protocol the controller uses? If both are missing, what protocol would you want to use? And last but not least: how should you get the data in the analysis program (e.g. store the received data in a file and consequently open it in the PC program or does this program provide a means to create some sort of plug-in)?
