Send command every 30ms

[oliva]

Hi,
I have an application which acquire, process and visualization data. I need every 30ms send command via serial port. I don’t now how to control that. I try to use Timed look, but then the whole application doesn’t make anything else-only send the command.  I suppose I don´t know how to correct set the timed loop… Or is there any other way how to control that?

Thank you,

Oliv

What you don't seem to understand is basic LabVIEW dataflow. When the timed loop starts, that is the only that will exeucte until you press the 'Stop Send' button. If you had used the regular while loop, you would have the same situation.

You could pull out the timed loop of the main while loop and run it in parallel. You might also try putting just the VISA Write code in the timeout event. Change the timeout value. Having a timeout of 0 is wrong anyway.
