I didn’t find any link explaining exactly how to set it up, basically do we to use a while loop in the autonomous VI so it reads the joystick or It will Read inputs from Teleop VI
Yes, the joysticks are not cached this year, so you can read them just like in Teleop.
See “New for this year”:

The robot will run the Autonomous code as in previous years. The difference is that the joystick data will be live instead of frozen.
