/**
|
|
* This sample program shows how to control a motor using a joystick. In the operator
|
|
* control part of the program, the joystick is read and the value is written to the motor.
|
|
*
|
|
* Joystick analog values range from -1 to 1 and speed controller inputs as range from
|
|
* -1 to 1 making it easy to work together. The program also delays a short time in the loop
|
|
* to allow other threads to run. This is generally a good idea, especially since the joystick
|
|
* values are only transmitted from the Driver Station once every 20ms.
