LabVIEW program hang after starting

[Ziheng]

When i click run once/continuously, my program will cause my laptop to hang and had to force restart the pc.

You must be doing something very wrong if you actually need to restart the laptop instead of just aborting run.

Could you save your VI for older version (2018 or 2019) please?

I can't look at the code, but do you have some greedy loops? That can cause the computer to be very sluggish, but you should be able to use ctrl+alt+delete to get the task manager and abort it.

You have a while loop that is functionning at maximum velocity ==> meaning your computer CPU capacity.

You need to add a waiting time (even a small one) to minimize your CPU usage.

thank you! my problem is solved after implementing a Wait

So it was a Greedy loop? Good guess from me. 🙂
