//This code reads A1 and A3 in free running mode. If the values are higher than threshold, it outputs the cumulative number of events
//and the time since the last event in milliseconds. 

//the commented out part at the bottom can be used to output the actual data and is what we've been using to make some plots.
//this whole thing runs in a loop and is a long way from true realtime.

//at 40ns incident coincidence the output lasts for 150ns - plenty for the DUE to capture.
