Joystick Issues

During our testing period, we have found a bug when using the new game controllers and/or the old game controllers. First off, the issue. When using the new controllers, a new logitech driver is installed on the computer. With the game conroller in the “d” setting (switch on the back side of the joystick) the game controller will run the same as last year’s with x,y (also known as x1,y1) on one thumb-joystick and z and z rotation (also known as x2,y2) on the second thumb-joystick. With the new game controller in the “x” setting, the second thumb-joystick (the one of the right) will run the top-hat (little pad in the upper left of the game controller) and the two triggers in the back of the controller now change the values of the previous x2. Now the main issue. Some computers will recognize the old game controller as the new ones with the “x” setting on. This means that the second thumb-joystick now runs the top-hat, the back triggers don’t work and all buttons now map to different values. This bug has nothing to do with FCS, it is a driver recognition issue and doesn’t happen on all computers. Although, we recommend that during the competition to use only new game controllers on the “d” setting and have teams make sure that their robots work on the “d” setting.
