NI 6602 Write and Read Frequency

[Kobi_K]

Hi all ,

I Have NI 6602 timing card and i'm trying to use it in order to write and read using the

DAQmxWriteCtrFreq (taskHandle1, 0, 1, 10.0, DAQmx_Val_GroupByChannel, &freq, &duty, &writtenVal, 0);

and

DAQmxReadCounterScalarF64(taskHandle2,10.0,&dataVal,0);

what i'm trying to do is to write to ctt0 and to read from ctr7 ( they are crossed in the card )

i'm having a bit problems with that can some one give me a tip on how to do it properly ?

just write freq to ctr0 and read freq from ctr7.....

After a few things i only need to make an output counter frequency...

but i just didn't make any progress any one knows how ?

You should have the following sample installed on your PC that may help you in this task: DigPulseTrain-Cont.prj (it could be located in \program files\National Instruments\CVIx\samples\daqmx\counter\generate pulse folder)
