Here is the situation:
We are trying to use our joysticks and jaguars.Serial port was only a try, you can ignore it if you want.
Our java code:
Code:
package edu.wpi.first.wpilibj.templates;
import edu.wpi.first.wpilibj.GenericHID.Hand;
import edu.wpi.first.wpilibj.SimpleRobot;
import edu.wpi.first.wpilibj.RobotDrive;
import edu.wpi.first.wpilibj.Joystick;
import edu.wpi.first.wpilibj.Jaguar;
import edu.wpi.first.wpilibj.Watchdog;
import edu.wpi.first.wpilibj.SerialPort;
import edu.wpi.first.wpilibj.visa.VisaException;
import edu.wpi.first.wpilibj.RobotBase;
public class RobotTemplate extends SimpleRobot {
RobotDrive drive = new RobotDrive(1,2);
final int baud = 9600;
final int dataBits =8;
SerialPort sp;
Watchdog wd;
public void autonomous() {
System.out.println("autonomous OK");
wd.feed();
wd.setEnabled(false);
drive.tankDrive(2, 2);
}
public void operatorControl() {
System.out.println("Operator OK");
wd.feed();
try
{
sp = new SerialPort(baud,dataBits);
}
catch(VisaException vs)
{
}
Joystick driveJoy= new Joystick(1);
Jaguar leftControl = new Jaguar(1);
Jaguar rightControl = new Jaguar(2);
if(driveJoy.getTrigger())
{
leftControl.set(driveJoy.getY());
rightControl.set(driveJoy.getAxis(Joystick.AxisType.kX));
}
else if(driveJoy.getRawButton(2))
{
leftControl.set(driveJoy.getThrottle());
rightControl.set(driveJoy.getAxis(Joystick.AxisType.kThrottle));
}
else if(driveJoy.getRawButton(4))
{
leftControl.set(driveJoy.getMagnitude());
}
}
}
And here is the console output:

The driver sitation do not permit me to control both teleoperated and autonomous control. When i press enable the clock starts but stops after 3 seconds. Than it says "Teleoperated/Autonomous Disabled" and "Watchdog Not Fed".
Is the problem about my code? What should i do?
