MEAN returns NaN?

Thanks. But my question is how to keep timing and not have NaN?

If you stubbornly want to keep your existing timing (not recommended!), just place the upper code in a case structures and only execute it if the array size is nonzero.

Hi, I put 100 sample per channel, and I have the same issue NaN!

[altenbach]

Why not put an indicator on the received 2D array and see what it looks like.

We cannot really tell how things are connected from a picture, so please attach your VI.

(I have no idee why you now think it is a good idea to pollute your diagram with local variables. That stop button should be latch action and wired inside the loop. Writing a control to a local variable of itself is just plain silly! I think you need to start with some basic tutorials. And please (please!!!!) resize your index array to the required number of outputs).

What everyone is saying is to wire a fixed number to the DAQmx read VI instead of default, ideally 1/10 th of the sample rate.

I got it Thanks all.

Hi, I attached my VI. I have another two while loops not included yet, so I need one stop button to control all the three while loops.

Thx
