I have a riddle for you. Given a system with real time processes. One process (process M) monitors some quantity (say, temperature) and makes measured values of the quantity available for another process (process A). Process A retrieves the measured temperature once in a while and takes some

I think that analog DAQ with 30 channels would be an overkill for such an application. If you need to give each competitor 4 options, why not choose between one of the following options: 1. 120 digital channels (5 digital DAQ modules at 24 channels each) and provide each competitor with 4
