Hi,
I ran into a problem using a NI-9361 counter in a cDAQ chassis.
The hardware features timed output, so I can set the sample rate to lets say 10kHz and collect the data like analog data.
Is there a mode to run the hardware in "old fashion" counter mode? I'd like to have one single entry in the output-array for each falling edge (without reading the same data over and over again if the signal has not changed).
In my application I need to decode a digital signal and I need to know the times between falling edges. At the moment I read the timed data and look for changes in the values (assuming that the times between falling edges differ a little bit). Every now and then the timing of the signal is so accurate that there's no change in the output data stream. Thus I miss this edge.
I have found a workaround to check for missing edges, but that need a lot of calculation power.
The best solution would be to get only the times of the edges fron the hardware. Is that possible with the 9361?
