how can i control a servo??
My airframe is standerd fixed wing UAV.
I am using Pixhawk 4 flight controller and Qgroundcontrol.
I want to actuate servo autonomously to drop a payload in a waypoint.
I don’t want to use transmitter switch for servo control.
i am connecting the control surface’s servos to FMU PWM Out of power distribution board and FMU PWM In is connected to I/O PWM Out of Pixhawk4.
Where should i connect the payload drop servo ??
What parameters should i change in QGC??
what should i do in mission plan??
firmware in my Pixhawk4 is px4.
must I switch to mission planner and ardupilot firmware or it can be in QGC and px4 firmware??
