We are currently using a Preferences object in our code, to store/retrieve various tuning parameters like PID coefficients.
Here's the snippet of code that instantiates/uses the Preferences:
**********
<RobotMap.cpp, in the static init() method>
Preferences *prefs = Preferences::GetInstance();
double tilter_p = prefs->GetDouble("Tilt_P", 1.0);
double tilter_i = prefs->GetDouble("Tilt_I", 0.0);
double tilter_d = prefs->GetDouble("Tilt_D", 0.0);
// BEGIN AUTOGENERATED CODE, SOURCE=ROBOTBUILDER ID=CONSTRUCTORS
LiveWindow* lw = LiveWindow::GetInstance();
....
***********
On the smart dashboard side, we transition to Teleop mode, enable it in the driver station, and then add the "RobotPreferences" widget, but the above preferences don't show up. (Actually, nothing shows up in the widget). Other controls are communicating Ok w/the robot code, just not the Preferences.
So we push the "Save" button on the smart dashboard side, reboot the robot, and still nothing shows up in the "RobotPreferences" widget.
We think our usage is correct (we've based it on the documentation in the 2013 screensteps live at
http://wpilib.screenstepslive.com/s/...martdashboard).
Are we missing some sort of important initialization here in order to get this to work?
