daq mx start task stucks when UI action

[DiegoDC]

 Hallo everyone!

I need to put "DAQmx start task" inside a loop as shown in the attachd picture. The problem is that while it is running, if I do some UI action, for instance click on the front panel, open a menu, etc..it happen that DAQmx start waits until the UI action has finished (I close the menu, etc..). What may be the cause? What is it waiting for? Is it a problem of functions runningin the same thread?

Thank you

diego

First off, try not stopping the task through every iteration. That Read VI will try to restart the task every time, and that can take a while.

Also, your loop doesn't have a latency delay. And as you probably know, your data indicators are not wired .
