Cadensed loop containing long time operations

[Arnaud_]

Hi,

I'm writing a program where I need to read an analog value with a high rate (say 10kHz), and depending on the value, I'll have to start a counter pulse whose length may be longer (10ms). If I make a loop where I read my DAQmx input at 10kHz, most of the iterations will last 100µs as expected, except for the ones where I send a pulse which last 10ms.
Is there a way to avoid this problem and go to the next iteration without waiting for the pulse to finish?

Thanks in advance,
Arnaud

I would use two parallel loops. One with the AI and the other with the CO task.
