The Coincidence Detective

Plan for today is to test the on-board coincidence detection code, as soon as Ray is done with his data collection on the Lecroy.

I keep forgetting, I've been meaning to stop by Fouraker's and pick up a couple of 40-pin headers and/or sockets that I can mount on the Wi-Fi board.

Ray is having the students work on the paper.  I recommended to Darryl that he make a new up-to-date figure of the FPGA design based on ideas from the architecture diagram from my Grad Seminar talk (5th slide), and the old draft slides in the Dropbox file "FEDM_design\design notes\Input Capture.odp", which are more up-to-date that the figure that Darryl was using originally.

Didn't get to the coincidence detection today.  However, in his scope tests on the LeCroy, Ray found that the pulse height peak in the histogram totally depends on where the threshold level is placed - meaning the scope is basically totally unreliable for collecting any real scientific data.
