Build and Deploy Successful, No Movement

[Team_4008]

We have all green lights on Drive Station, and all of our wiring looks good (that we know of). Everything deploys well, but we get no response from the robot when moving the joystick. I did notice that our motor controllers keep blinking, and we get a continuous message saying " * Default teleopInit() method… Override me!
Default disabledInit() method… Override me!"
Any ideas?
I’ll upload wiring if I can get the picture up
Robot.java (1.3 KB)

What pattern are the controller lights flashing?

[Team_4008]

Motor controllers (Sparks) are constantly blinking blue, no matter what state the robot is in.
RSL is solid whenever enabled.
PDP is flashing yellow lights constantly as well.

[Phlogiston]

I think the errors are because you don’t have those methods in your robot class.

[Team_4008]

Were they needed? Sorry, we’re starting from scratch on coding knowledge this year. We just stole the example code for now to try and get our dummy bot to move.

some reference code from our tank bot

package frc.robot;

import edu.wpi.first.wpilibj.TimedRobot;
import edu.wpi.first.wpilibj.Joystick;
import edu.wpi.first.wpilibj.Victor;
//import edu.wpi.first.wpilibj.DifferentialDrive;

public class Robot extends TimedRobot {
    Victor motor0;
    Victor motor1;
	Joystick controller;
	//DifferentialDrive m_drive;

	@Override
	public void robotInit() {
		motor0 = new Victor(0);
		motor1 = new Victor(1);
		controller = new Joystick(0);
        //m_drive = new DifferentialDrive(motor0, motor1);
	}

	@Override
	public void teleopInit() {
	}

	@Override
	public void teleopPeriodic() {
        motor0.set(controller.getRawAxis(1));
        motor1.set(-controller.getRawAxis(3));
// this code above is actually tank drive
        //m_drive.arcadeDrive(controller.getRawAxis(0), controller.getRawAxis(1));
    }
}

I would also go to the FRC Driver Station and make sure you’re getting joystick inputs to the right axes.

Just to confirm, you’re using TalonSR Spark(not SparkMax) controllers and have them plugged into PWM ports 1 and 2 (note that the ports on the Rio start at 0 (zero))?

The absence of robotInit, teleopInit, etc methods is inconsequential. The code will use a default method from the parent class in this case (which is where those “Override me” messages are coming from)

Looks like Sparks.

[Team_4008]

Joysticks are right, and we’ve added disabledInit and teleopInit, still no movement. Our Sparks won’t quit flashing no matter if the robot is enabled or not. We did get something new in our rioLog (listed below). We’re using Sparks in ports 1 and 2.

[Fletch1373]

Yes, you’re correct. Fingers got ahead of my brain for a moment

[Amicus1]

Did you by any chance hit space bar? Can you send a pic of your driver station?

[Team_4008]

Hit enable, not space bar. No error codes in Driver Station anymore. Same picture when enabled

[Fletch1373]

Constant blue flashing means Brake Mode with no signal (http://www.revrobotics.com/content/docs/REV-11-1200-QS.pdf), which means either the wiring is bad, you’re wired into the wrong port, or your code is using the wrong port numbers.

[Amicus1]

So we need to see your wiring to help.

[Team_4008]

Just switched our PWM cables around, right ports, plugged in backwards. facepalm

[Fletch1373]

That would definitely do it. Glad you got it working
