Can't see any values on dashboard

This will create a new project that has all the framework you need to implement the dashboard. On the left side of the diagram, it has a "cluster" defined (same as a struct in C) with all the data that it will parse... one for high priority and one for low priority. You will notice that this set of data matches that in the DashboardDataFormat.cpp.



Both. You should change the format of the structure to include the data that you are interested in displaying. The structure has to be the same on the dashboard and the robot code.

Thank You!! Everyone kept saying MODIFY THE DASHBOARD!! but I am having enough trouble figuring out the encoders right now, and we have more sensors we want to set up. Where is the diagram though, I see the project explorer and it lets me open of the GUI. Other than figuring that out, I have never used labview. Since you have been so helpful, would you mind me asking you about an Encoder Example, maybe even one that sends it to the dashboard? If you could point me to something that would be very helpful. WPI documentation seems to be very lacking in the encoder area.

Here's some code for unit testing the Encoder class:

	double position4x, position2x, position1x;
	DigitalInput qA(5); // Digital I/O 5 on slot 4
	DigitalInput qB(6); // Digital I/O 6 on slot 4
	Encoder encoder4X(qA, qB, true);
	Encoder encoder2X(qA, qB, true, Encoder::k2X);
	Encoder encoder1X(qA, qB, true, Encoder::k1X);
	// 6 inch wheel (pi*d) is 18.85 inch circumference; 24:40 tooth sprockets; 250 pulses per rev.
	encoder4X.SetDistancePerPulse(18.85 * 0.6 / 250.0);
	encoder2X.SetDistancePerPulse(18.85 * 0.6 / 250.0);
	encoder1X.SetDistancePerPulse(18.85 * 0.6 / 250.0);
	Jaguar rightMotor(2);
	rightMotor.Set(-1.0);
	Wait(2.0); // wait for motor to get up to speed
	encoder4X.Reset();
	encoder2X.Reset();
	encoder1X.Reset();
	encoder4X.Start(); // start counting
	encoder2X.Start();
	encoder1X.Start();
	Wait(5.0); // wait for some distance to be covered
	position4x = encoder4X.GetDistance(); // get position in inches
	position2x = encoder2X.GetDistance();
	position1x = encoder1X.GetDistance();

This code is only interested in position, not speed. Hope this helps.
