Programming the teleop

[Twisted eric]

My programming team are stuck

like the title says I'm tying to program I don't know what I'm missing


code

package edu.wpi.first.wpilibj.templates;

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.Watchdog;

public class Demonized extends SimpleRobot {

RobotDrive drive = new RobotDrive(1, 2);
Joystick leftStick = new Joystick(1);
Joystick rightStick = new Joystick(2);
Watchdog Fenrir = Watchdog.getInstance();

public void autonomous() {
while(true && isAutonomous() && isEnabled())
for (int i = 0; i < 4; i++) {
Fenrir.feed();
drive.drive(0.5, 0.0); // drive 50% fwd 0% turn
Fenrir.feed();
drive.drive(0.0, 0.5);
}
drive.drive(0.0, 0.0); // drive 0% fwd, 0% turn
}

public void operatorControl() {
while (true && isOperatorControl() && isEnabled()) // loop until change
{
drive.tankDrive(leftStick, rightStick);
Timer.delay(0.005);
Fenrir.feed();
}
}
}



help will be much appreciated

You need to "feed" the watchdog timer in the operatorControl() method. I'm not sure if that's what you're seeing, but I would expect that you are getting a "Watchdog not fed" message on the driver station.

Insert a Fenrir.feed() in the loop with the drive.tankDrive() call.

Thank you that was what i was missing any help with the pneumatic compressor.

add a Siberian.start() to the outside of your while loop

which wiled loop auto or tele op

OH
and can everyone help with sensing pressure and every thing first time using java.

[Robototes2412]

i reccomend you make a setupRobot method for stuff like that.

insert the following inbetween the autonomous and teleop code

void setUpRobot() {
Siberian.start();
Fernir.feed();
}

then just add setUpRobot(); to your teleop and autonomous code.

That should fix it

Thanks

do you know how to sense pressure value and auto shut off

Thanks in advance and sorry for so-many questions.

[Robototes2412]

Dude, its ok, i had the same questions.

it will automatically shut off as long as the wiring is correct (check the diagrams), so programming can now rest easy.

in the pneumatics manual here (http://www.usfirst.org/uploadedFiles...%20Rev%20-.pdf)

says that there is no default program in the cRIO to control
the compressor power.
