Hi,
I am using DAQmxCreateCICountEdgesChan(..) API to create a counter input channel to count the number of edges. this API takes a parameter called "countDirection" whose value is DAQmx_Val_ExtControlled. Can anyone tell me how this parameter helps in the counting. I have noticed that it is similar to DAQmx_Val_CountDown value i.e. it decrements the count value.
I am generating digital pulses at CTR 0 and measuring using CTR 1, so i connected CTR 0 OUT to CTR 1 GATE. Any other external connections are needed to use the DAQmx_Val_ExtControlled value?
Thanks,
Priya.
