I have a 9421 Digital Input module. I am only using one port (0). The line is "high" all the time. I can see this on the LEDs and on the MAX tool. I can toggle the line and see the LED and MAX change, so I know I have the thing wired correctly. But under normal operation, it is always ON.
Problem is, when I run LabVIEW in trace mode with a probe on the DAQ ExpressVI output, I can see that every other time my code cycles, the output flips from TRUE to FALSE and back again... and so on. The DAQ ExpressVI is inside a while loop.
Any thoughts?
