Jaguar problem?

[shuhao]

We just have the jaguars hooked up to the cRIO board and we're having some trouble with the Jaguar. We hooked the Jaguar's output to a multimeter to test our circuits.

For some reason the code is not working.

public class The2012Robot extends IterativeRobot {

Command autonomousCommand;
GameController gc = new GameController(new Joystick(1));
Jaguar j;

/**

*/

public void robotInit() {
// instantiate the command used for the autonomous period
// autonomousCommand = new ExampleCommand();

// Initialize all subsystems
// CommandBase.init();
j = new Jaguar(2, 1);
}

public void autonomousInit() {
// schedule the autonomous command (example)
// autonomousCommand.start();
}

/**
* This function is called periodically during autonomous
*/

public void autonomousPeriodic() {
Scheduler.getInstance().run();
}

public void teleopInit() {
// This makes sure that the autonomous stops running when
// teleop starts running. If you want the autonomous to
// continue until interrupted by another command, remove
// this line or comment it out.
// autonomousCommand.cancel();
}

/**

*/
public void teleopPeriodic() {
Scheduler.getInstance().run();
Point rightStick = gc.getRightStick();
System.out.println(rightStick.y);
j.set(rightStick.y);
}
}


The GameController code is verified to be working, and rightStick.y is a value between -1 and 1

and our Jaguar is connected to PWM1

Try removing the slot from your Jaguar object.

Jaguar j = new Jaguar(1);

Wouldn't hurt to try. We had a similar problem getting our drive train to work, and this seemed to fix it. I'm still not sure how the new cRIO slots work yet... so I guess I'll have to get back to you on that.

I'm still not sure how the new cRIO slots work yet... so I guess I'll have to get back to you on that.

If you have the old cRIO, any module in slots 4-3 is module 1, regardless of the slot and and module in slots 5-7 is module 2 regardless of the slot. Any module in slots 1-3 of the new cRIO is module 1 and the module in slot 4 is module 2 even though it's in slot 4. The code defaults to module 1 (slot 1, 2 or 3) unless you say otherwise. Thus, getting rid of the slot number in the code should work. It's confused a fair number of people here from what I can tell.

No effect..

and I'm also on the new cRIO

Also prehaps I should clarify that the multimeter doesn't show anything other than 0.

We're having the same problem. There is already some discussion about the same issue in this thread (http://www.chiefdelphi.com/forums/showthread.php?t=100275).
