How to display number of samples received.

[maverikk]

Hi,

So want to display how many samples I have read. I have seen in some discussions that i should use "DAQmx read property node" but where exactly should i place it in my VI. Also I want to stop my code after acquiring exactly 675 samples. How should i do it? Attached is my receiver vi.

Hi maverikk,

I want to stop my code after acquiring exactly 675 samples.

Remove the loop from your VI.

Then change "number of samples per channel" to a constant and set its value to 675.

Finished.

Why do you need a property node to know the number of samples read?

Just use ArraySize on your Y array in the waveform…

Why do you need this at all? When you set DAQmxRead to read 675 samples and it returns without error then you got exactly 675 samples…
