Hello everybody,

I have a issue that maybe someone can clear me up. Basically, I built a GUI (graphical user interface) and I am using it to make some analyses while acquiring real-time data from a National Instrument hardware.

The problem is that at some time the Background acquisition stops without returning any error. Does anybody know why this happens or to what it might be related? Is there any way to solve this issue?

Thank you all.

Yes use drawnow to force the GUI to update

在 MATLAB Online 中打开

I checked the other thread, maybe this solution might help, it will stop updating GUI once process is closed

while ~daqSession.HasExited 
    drawnow
    pause (0.1) % Updates GUI every 0.1s 
end
