timing measurement between finite pulses

[GerdW]

Hi Nitin,

I'm surprised you see anything at all in the chart when your "data" array is empty…

Did you do any debugging? Is there any error with the DAQmxRead function?

One note: you try to read 10k samples with a sample rate of 1kHz: this will take 10s. The default timeout of DAQmxRead is also 10s. Did you read the help for DAQmxRead regarding that matter? Again: did you do any debugging and did you check the error output?

Hi Gred

I am able to see samples now in array .

It would be grateful to you if you can let me know how i can search in rising edge in bunch of samples , as by the time i will process it one by one at the same time new samples will come .

hello Gerd

I can now traverse  the array and find out the transistions , But total transtion should be 22 , instead of them i am getting  less then 10 .

Can you please help me in this case ?

Hi Nitin,

total transtion should be 22 , instead of them i am getting  less then 10 .

Right now you search in blocks of 100 samples: are you SURE you have more than 10 transitions per data block?

Can you attach an example with some data set to default in your VI?
