This code will adjust the controller to work with your joysticks so that they default at 127 when released. There is no need to adjust the wheel on the side; however, the wheel should be as close to the middle so that it does not max out the controller.
The joysticks provided by FIRST proportionalize poor handling, so our students came up with a solution. This whitepaper explains the advantages of converting the linear curve of the joystick into an exponential one, and how it can be done.
An example low pass filter for the PWM outputs. Can be used for making the joystick less sensitive, as well as for general protection of the robot drive train motors.
Attached is a File pictorial for the new Joystick.
The large center button sends different OHM values for its 5 potential positions, and it is connected to the same pin numbers as the P1_wheel was last year.
This is in answer to my question:
1) Is there any electrical information on the p...
