Is a puzzlement. Can you post your code so we can go through it in detail, looking for anything that isn't quite right?

Both the pressure switch and spike PWM are in the number 1 slots.

I think you're talking about the 3-pin connections on the Digital Sidecar, but in case you're talking about the cRIO module, that needs to be in the number 2 slot.
