sending variables from driver station to robot?

If you are using the PIDController class, there is already a PID widget on Smart Dashobard that lets you change P, I, and D, and the setpoint. You can add the PIDController as an actuator with LiveWindow, and test whatever you want.

Please pardon me if my question seams redundant.

We are using Java for our cRIO and the Java version of the Smart Dashboard. How can we have an operator/driver enter number values
in the Smart Dashboard (or other software interface) and have them "pushed" to the cRIO as values to use in certain parts of the code?

For example, we have an ultrasonic sensor that feeds the cRIO an analog signal based on how far the sensor is from the wall (front mount). We know that we need our robot to be 7'/84" from the wall to shoot for and make the high goal. In autonomous, I would like to have the ability for the driver to enter that value in the driver station and have it passed to that filed in the autonomous code to allow on site tweaking w/o having to do multiple downloads to the cRIO.

Thanks.
