Camera controls using Gamepad Joystick

Hi all,
Is it possible to control gimbal using a gamepad connected to GCS?
I have connected the gimbal’s PWM pins to FC’s AUX pins, which parameters should I change in order to control gimbal via gamepad joystick?

Hi @Aman_Chandak , I never tried to do that, but it seems that it is a feature available only for Ardupilot

Thanks for the info. Do you know anybody could make these changes?
