Dashboard display

[Mike AA]

I am starting, after all my time working with Labview, to modify the dashboard and use some other sensors. We are hooking up an ultrasonic sensor which I can figure out how to read and display on the dashboard using the dashboard read and write numbers. Following code tutorials and examples I am sure I can get that going easily.

However we would like to put an indicator (already on the dashboard) to show when the air-compressor is running. I have a simple indicator on the dashboard. I am not sure how to read the compressor spike status or the pressure switch status off the robot. Is this even possible without causing the code to crash via recalling the variables?
