Does anyone know how Black Shark considers the vrious buttons and sliders of the X52? When I try to assign an X52 button or slider I see a list of joystick button names that look like JOY_BTN109. For instance if I wish to assign "Collective Up" to the action of pulling back the Z Axis slider I can't identify which button (name) does what. Is there a list somewhare that identifies how Black Shark names the buttons and sliders?
