I am trying to get a simple gimbal servo working.
1) Servo (Towerpro SG90) is connected to AUX1. Rail is powered from AFROESC BEC, with zener. When I use this interface:
the servo cycles, so I presume, it is powered correctly.
2) Pot on my TX is binded to CH8, which is callibrated and the bar in Mission Planner moves from 990 to 2014, so I presume pixhawk gets input from my radio.
3) I configure the gimbal page the following way:
but the servo won't move. I have tried with MNT_TYPE=0 and MNT_TYPE=1, no effect.
Unless it woks only with the motors spinning? Or armed only? Maybe something is wrong with the PWM signal from the pixhawk to te servo? If so - why it works from the test screen (screenshot #1)
Any help appreciated. I have spent hours on this issue.
P.S. Multicopter v3.3RC9, Mission Planner 1.3.31

I finally resolved this, by :
1) uploading firmware 3.2.1
2) making the gimbal works (change mnt_type to 3 in this version)
3) upgrade to the FW 3.3.3.
And it works. ;-)
I have the exact same issue, this was working in the previous firmware version, (mnt_type not present at this time).
At this time, no way for me to get any output on channels over RC8... Really confusing
