No compressor light on PCM, no compressor power, no CAN recognition of compressor

[techplex]

Make sure you have at least one Solenoid or DoubleSolenoid decleared in your code. The compressor will not be initialized without having at least one:

Solenoid name = new Solenoid(1);

This code should actuate the double solenoid based on joystick button:

package org.usfirst.frcEasyJ.team5122;

import edu.wpi.first.wpilibj.IterativeRobot;
import edu.wpi.first.wpilibj.Joystick;
import edu.wpi.first.wpilibj.DoubleSolenoid;

public class MyRobot extends IterativeRobot {

    Joystick JS1 = new Joystick(1);
    DoubleSolenoid DValve1 = new DoubleSolenoid(1, 2);
    public void autonomousInit() {

    }
    public void autonomousPeriodic() {

    }
    public void teleoperatedPeriodic() {
        if (JS1.getRawButton(1)) {
            DValve1.set(DoubleSolenoid.Value.kForward);
        } else {
            DValve1.set(DoubleSolenoid.Value.kReverse);
        }

    }
    public void teleoperatedInit() {

    }
}
