Error with joystick controller and driver station
I am the programmer from team Yellow Jacket 3345, the driver station is giving me error about the joysticks are not plug in,but ti is plug in right and all show green but we all check the program is no error.And we don't know the problems.

Re: Error with joystick controller and driver station
Joysticks are indexed starting at 0. Change your Joystick numbers from 1 & 2 to 0 & 1.

Re: Error with joystick controller and driver station
Just curious, why do you have TWO RobotDrive objects? RobotDrive does support 4-motor drive. There is no reason to have two RobotDrive objects.

Re: Error with joystick controller and driver station
Are they in port 0 and 1 in the SmartDashboard as we? (Inside the driver station go to USB Devices and check the numbers to the left of the joysticks highlighted green).

Re: Error with joystick controller and driver station
You have a while(true) in your teleopPeriodic() method. You should do that in an IterativeRobot implementation. Try changing:
Code:
@Override
public void teleopPeriodic() {
while(true) {
robotDrive1.arcadeDrive(leftJoystick.getY()*driveBaseSpeed, rightJoystick.getX());
robotDrive2.arcadeDrive(leftJoystick.getY()*driveBaseSpeed, rightJoystick.getX());
gearMotor.set(rightJoystick.getY()*gearMotorSpeed);
if(rightJoystick.getRawButton(4)) {
fuelGate.set(1.0*fuelGateSpeed);
} else if(rightJoystick.getRawButton(5)) {
fuelGate.set(-1*fuelGateSpeed);
} else {
fuelGate.set(0);
}
if(rightJoystick.getRawButton(6)) {
scissorLift.set(1.0*scissorLiftSpeed);
} else if(rightJoystick.getRawButton(7)) {
scissorLift.set(-1*scissorLiftSpeed);
} else {
scissorLift.set(0);
}
}
}
Code:
@Override
public void teleopPeriodic() {
// teleopPeriodic() should do something and exit right away (it should not loop forever)
// while(true) {
robotDrive1.arcadeDrive(leftJoystick.getY()*driveBaseSpeed, rightJoystick.getX());
robotDrive2.arcadeDrive(leftJoystick.getY()*driveBaseSpeed, rightJoystick.getX());
gearMotor.set(rightJoystick.getY()*gearMotorSpeed);
if(rightJoystick.getRawButton(4)) {
fuelGate.set(1.0*fuelGateSpeed);
} else if(rightJoystick.getRawButton(5)) {
fuelGate.set(-1*fuelGateSpeed);
} else {
fuelGate.set(0);
}
if(rightJoystick.getRawButton(6)) {
scissorLift.set(1.0*scissorLiftSpeed);
} else if(rightJoystick.getRawButton(7)) {
scissorLift.set(-1*scissorLiftSpeed);
} else {
scissorLift.set(0);
}
// Removal of while(true) loop
// }
}
