I'm trying to use the aux pins in the pixhwak to control servo or leds. I am able to use the RC9 / RC10 / RC 11 for the same. But i want to extend it to RC12 / RC13 / RC 14 .i.e. Aux out 53/54/55 in pixhawk. But there are no servo buttons in mission planner to control the pins other than RC5 - RC 11 . Please help me to do the same. I also tried to give PWM signals from RC5 - RC8 to control a servo. It doesnt work.
