Invalid Conversion

Technical C/C++
1

Hi everyone,

This is probably an easy one but I’m just not seeing the answer. I’m trying to incorporate code for the IR sensors and everything seems fine except for one little error that says "invalid conversion from “int” to “DigitalInput.”

Here’s a snapshot of some of the code.

class RobotDemo : public SimpleRobot
{
	RobotDrive myRobot; // robot drive system
	Gamepad controller;
	Jaguar one;
	Jaguar two;
	Jaguar three;
	Jaguar four;
	DigitalInput *left;			// digital inputs for line tracking sensors
	DigitalInput *middle;
	DigitalInput *right;
	DriverStation *ds;
	AxisCamera& camera;
	
	
public:
	RobotDemo(void):
		myRobot(9, 10, 2, 1),	// these must be initialized in the same order
		controller(1),
		one(9),
		two(10),
		three(2),
		four(1),
		left(1),
		middle(2),
		right(3),
		ds(DriverStation::GetInstance()),
		camera(AxisCamera::GetInstance())
		
	{   <------- ERROR HERE

		GetWatchdog().SetExpiration(0.1);

Thanks for your help!

The problem is that you’re declaring pointers to DigitalInputs, and then trying to initialize them in the initialization list. You either need to declare them as actual DigitalInput objects (no *) or instead of left(1), middle(2), right(3), you need to have inside the constructor (where you note “error here”):
left = new DigitalInput(1);
middle = new DigitalInput(2);
right = new DigitalInput(3);

Hope that helps!
