Hi everyone, I do not have yet a Teensy to play with, so I have been playing with my DUE. I just wrote a quick update on the Arduino DUE forum. I link it here (https://forum.arduino.cc/index.php?topic=400516.15) if somebody wants to see how far I have got using that other platform. A long story...

Dear all, Regarding a comment of Defragster in post #18 "should stay high a min of 5-10 ns to be detectable": I need to check it, but the TTL from the PM should stay HIGH longer than 10ns. Regarding a comment of Defragster in post #19 "How long does a sample period run with photon firings?"...

I was going to say it... (I was not sure that somebody was going to answer a 2 years old thread...) Should I delete this thread?

OK. I see that my explanation of what I have in mind is not clear enough... I try again. I have done a new diagram. The idea is to write down in a "Buffer" the number of "Clock Ticks" since the "Reset/Trigger Signal" when a "TTL from Photo Multiplier" signal arrives. So, two physical...

Thanks XFER. The idea is to fill a buffer with the number of clock ticks since a trigger signal happens (SOURCE in the figure) each time that a rising edge occurs ("Sample Clock" in the figure, this is coming from the photon multiplier). Because a clock tick is associated to a time, it is...

Dear all, I am considering the Teensy3.6 (the fastest Arduino like board that I know of) to develop a photon counter (I am physicist). I am looking to reproduce the "Buffered Edge Counting" mode found in many National Instruments boards. I attached a figure from the National Instruments...

Dear all, I was wondering if somebody has implemented the Photon Counter and could report real values... Also, I was wondering if the Teensy3.6 could be set up similar as the National Instruments boards counters work, see attached figure, and at which speed. My objective is also to count...
