Re: Pneumatics system code

Any help with this issue would be greatly appreciated.

Also my team is pressuring me to re-check the code, because they think that is the case.

Here is the current code that I am running:

Code:
package edu.wpi.first.wpilibj.templates;
 
import edu.wpi.first.wpilibj.Jaguar;
import edu.wpi.first.wpilibj.Joystick;
import edu.wpi.first.wpilibj.RobotDrive;
import edu.wpi.first.wpilibj.SimpleRobot;
import edu.wpi.first.wpilibj.Timer;
import edu.wpi.first.wpilibj.Compressor;
import edu.wpi.first.wpilibj.Relay;
 
public class RobotTemplate extends SimpleRobot {
    
    RobotDrive chassis = new RobotDrive(1,2);
    Joystick mainStick = new Joystick(1);
    Jaguar jaguar = new Jaguar(3);
    Jaguar jag = new Jaguar(4);
    Compressor compressor = new Compressor(1, 1);
    Relay spike = new Relay(7);
    
    public void robotInit() {
        compressor.start();
    }

    public void autonomous(){ 
        chassis.setSafetyEnabled(false);
        chassis.drive (-0.5, 0.08);
        Timer.delay(2.0);
        chassis.drive (0, 0.0);
    }
    
    public void operatorControl() {
        chassis.setSafetyEnabled(true);
        while (isOperatorControl() && isEnabled()) {
            double speed = mainStick.getY();
            double rot = -mainStick.getX();
            chassis.arcadeDrive (speed, rot);

            // Solenoid
                spike.set(Relay.Value.kReverse);
        }
    }
If somebody could please check over this code?

Re: Pneumatics system code

This line...
Code:
compressor.start();  // Relay port 1
...and this line...
Code:
spike.set(Relay.Value.kReverse);  // Relay port 7
...should be activating the green LED for Relay 1 and the red LED for Relay 7 on the Digital Sidecar when the robot is enabled in teleop mode. They should turn on regardless of whether Spikes are connected or not. If the LEDs are not activating and you are not measuring any voltage off of these ports, then my conclusion is that there is an issue with either your digital sidecar or the cable connecting it to your cRIO. The code looks fine to me, and it compiles without error in NetBeans.
