Digital input event handler

[Dar_Bahatt]

Hi-

My labview code needs to execute only when a physical switch is pressed by the user.

Is it possible to generate a DAQmx event for a level change on a digital input line of the USB-6343?

I am using LV2010 on a windows 7 machine.

Best,

Hi,

Yes it is possible to rise an event for a level change. You can use value signal property node.

Can you give more details?

Hi Dar,

  Please use Value(signalling) property of the indicator...Please see the screen shot.

Thanks!

In your method do I need to constantly monitor (loop with digital input read) the value of the

digital input associated with the UI indicator? If so, that would use system resources.

If possible, I prefer using a DAQmx event with an event handelr within a while loop. Not sure if

DIO can be set to generate an event.
