Pneumatics simply not working

[ksafin]

Hi,

We set up our pneumatics system today and simply can't get it to work.

We have a spike relay with two wires going to the PDB, and then 2 wires going to the compressor.

The compressor hooks up to the standard brass fitting configuration as defined in the FRC Pneumatics manual, and then some tubing goes to a T that enters an air tank and continues onward. The one that continues onward goes through a few things and eventually reaches our piston.

But that's beyond the point right now; our compressor is refusing to turn on.

We have a PWM cable going from the Spike to Relay port 1 on the Digital Sidecar; when power is on, the spike relay lights up.

We have a PWM going from the pressure switch on the pneumatic system to the Digital I/O slot 1.

Our programming language is Java, but any combination of code seems to not help.

Any ideas?
