Hi all!
I am trying to get the Edge Counter value from ni usb 6251 data aquisition card using analog session based interface in MATLAB R2011b. I always get the value zero from variable count. I have written the following code:
ai = analoginput('nidaq','Dev1');
hwinfo = daqhwinfo(ai);
hwinfo.DifferentialIDs;
hwinfo
daq.getVendors();
s = daq.createSession('ni');
s.addCounterInputChannel('Dev1','ctr0','EdgeCount');
count = s.inputSingleScan;
count
I have been used the driver software and i got the Edge Counter value successfully.
Thank you a lot.
