Passing a motor as an argument in a function

Technical C/C++

Hello, I am trying to pass a speed controller (victor) as an BYREF argument in a function and set its value, however, the motor wont turn on and I get no errors. Here is what it looks like:


void SpecialControl(SpeedController &Motor); /* prototype */
class Robot : public SimpleRobot
{
	Victor InitialMotor;
	public:
		Robot(void):		// these must be initialized in the same order 
		InitialMotor(1)
	{
		GetWatchdog().SetExpiration(0.1);
	}



void OperatorControl(void)
	{
		GetWatchdog().SetEnabled(true);
		SpecialControl(InitialMotor);
	}
};

void SpecialControl(SpeedController &Motor)
{
	Motor.Set(1);
}

Thanks in advance.

Give this a shot:


void SpecialControl(SpeedController *Motor); /* prototype */
class Robot : public SimpleRobot
{
	Victor *InitialMotor;
	public:
		Robot(void)
	        {
                       InitialMotor = new Victor(1);
		       GetWatchdog().SetExpiration(0.1);
	        }


                void OperatorControl(void)
	        {
		     GetWatchdog().SetEnabled(true);
		     SpecialControl(InitialMotor);
	        }
};

void SpecialControl(SpeedController *Motor)
{
	Motor->Set(1);
}

I have tried that, and it gives me these errors:

error: cannot convert Victor' to SpeedController*’ for argument 1' to void SpecialControl(SpeedController*)’

Thanks in advance.

Look carefully at this line, and make sure you didn’t leave out anything.

	Victor *InitialMotor;

Ah, finally, that compiles… I will see if it runs on the robot tomorrow. Thanks so much…
