Sampling at once frequency, but writing data to a file at a different frequency

[Amanda_H]

Have you tried using the DAQmx VIs instead of the DAQ Assistant express VI? The DAQ Assistant functions well within a simple code, but is not the best option for more complicated programs.

i have the same question. but i still have problem with your code, milqman

I have changed ur code a bit so u can read it. basically there are two while loops. the outer loop is used for sampling from fieldpoint devices at 100ms and inner loop is used to record date at a slower rate e.g., 10s, which is adjustable from input of the text box. It seems the inner loop is dragging the outer loop down.

could you correct me? Thank you
