you will most likely need the accumulator unless you are using a very small piston or actuator to hold enough air in the system to completely move your piston. I dont know the code but you basically just tell the robot that when the pressure reaches 120psi (i think that is the max for everything before your working system i.e before your pressure regulator) that the compressor needs to turn off. you get the pressure from the pressure switch connected to the digital sidecar. For the solenoids all i now is that by sending electricity to one side versus the other it actuates it...you do this with the solenoid breakout on the cRio
