Error
 
Hi, I have the following error displayed on the driver station when teleop is enabled:

Code:

ERROR: A timeout has been exceeded: RobotDrive...Output not updated often enough. ...in Check() in c:/Windriver/workspace/WPILib/MotorSafetyHelper.cpp at line 123
I am using the SimpleRobot example and I also used the following code as well and received the same result:

Code:

#include "WPILib.h"

class Robot : public IterativeRobot

{
        RobotDrive myRobot;
          Jaguar ballpicker;
          Joystick leftStick; // left joystick in USB 1 of the DS
          Joystick rightStick; // and right JS is in USB 2 of the DS
          Solenoid sol1;
          Solenoid sol2;
          Compressor compress;

  public:
  Robot():
                    myRobot(1,2), // Drive Motors

                    ballpicker(3), // Motor That Picks Up Balls

                    leftStick(1),
                    rightStick(2),

                    sol1(2,1), // MIGHT HAVE TO CHANGE FIRST COORDINATE BECUASE MODULES-
                    sol2(2,2), // HAVE CHANGED THIS YEAR!!!

                    compress(1,1)
 {
  // Any Constructor Code Here...
 }

                  void TeleopInit()
        {
      GetWatchdog().SetEnabled(true);
      compress.Start();
        }

                  void TeleopPeriodic()
      {
            GetWatchdog().Feed();
            myRobot.ArcadeDrive(leftStick); // Arcade Style--> Left Stick

            if (leftStick.GetRawButton(3))
            {
                    ballpicker.Set(0.1); // --> If Button 3-->Input-->10% Power
            }

            else
            {
                    ballpicker.Set(0.0); // --> If Button 3-->No Input-->No Power
                } // Left Stick Is For Driver/Ball Picker Up'er

            if(rightStick.GetTrigger()) // Right Stick Is For Shooter
            {
                    sol1.Set(true); // --> If Right Trigger-->Input-->Valve 1-->True
                    sol2.Set(false); // --> Valve 2-->False
            }

            else
            {
                    sol1.Set(false); // --> If Right Trigger-->No Input-->Valve 1-->False
                    sol2.Set(true); // --> Valve 2-->True
            }

            Wait(0.005); // --> Allows Time for Motor Refresh/Update

      }

};

START_ROBOT_CLASS(Robot);

I don't see any errors in my code and have had it checked by another individual as well.

Please help.

Thank You.

Re: Error
 
Is the robot working as expected despite the displayed error?

Re: Error
 
We also have this problem. When we have it all the pwms associated with the RobotDrive are disabled. All others work.

We have used feeding the watchdog as a work around. The MotorSafety true/false has not been a solution. I still cannot directly use those pwms without allocation errors and it does not work in my autonomous section. What we don't know is why this year's version of Windriver/robot image cannot use last year's code on the robot.
