Custom SmartDashboard Widget Repository

This widget is useful for debugging commands, because you can put them on the SD and then play with parameters and make sure they react correctly.

The ParameterCommand.jar file contains the widget, while the src folder contains the source for both the widget and the robot code. The robot code includes an example (RotateToCommand.java) from our code which demonstrates the usage of the ParameterCommand.

When you want to use put the command on the SD, you simply have to call:

SmartDashboard.putData(yourParameterCommand);

If you use RobotBuilder, the "Button on SmartDashboard" checkbox also works as long as your command has a default constructor.

When I tried to copy the classes to a Robot Project it said that the import edu.wpi.first.smartdashboard could not be resolved. Which library should I use?

Which classes? The only file that needs to in your robot project is ParameterCommand.java. The .java in the smartdashboard directory are the source for the SmartDashboard widget, which are only necessary if you want to modify the the code running in the SmartDashboard.

Where did you get the libraries for SmartDashboard source - I can't seem to find them.

Are you looking for the source for the SmartDashboard or the library jar file?

The source for the SmartDashboard is here: https://bitbucket.org/byteit101/oldsmartdashboard/src, but if you only want to write extensions for it, you need to add "HOME/wpilib/tools/SmartDashboard.jar" as a library in Eclipse/Netbeans.

Okay that makes sense. How do you deploy the widgets, then? None of this seems to be documented.

You have to put the .jar file containing the extension in "HOME/SmartDashboard/extensions".
