Re: Using Pneumatics with the CRIO?

GPIO = General Purpose Input/Output

That's just another name for the pins labeled "Digital I/O" on the Digital Sidecar.

Start() does indeed start a process that constantly checks the pressure switch digital input and turns the compressor spike on and off automatically.
You don't have to do the logic yourself (although you can if you really want to).
