Error

[msulaimain]

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

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:

#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.

Is the robot working as expected despite the displayed 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.
