ArduCopter Copter 4.0

Hello,
I have a CADDX GM3 gimbal which i connected to a pixhawk board, but I still cannot control the gimbal, I followed this instructions on how to connect it in multiple serial ports with no success, I updated the firmware to version 3.4 and tried again with no success. the gimbal is connected to a 3s battery. I will attach my parameter list here

Im thinking on connecting the pwm signal directly but I rather control it with the rx&tx cables.

Any help or point of view would be very appreciate it

What ardupilot firmware version are you on?

An alternative way if you are just wanting to fly through the camera is to use servo s-bus control.
SBus Servos — Copter documentation then use the gimbal config software to select the channels.

I have set my XF gimbal up with this and tested it out. Works great. Allows changing mode and sensitivity, head tracking through tx trainer port if you want it.

XF is the OEM for the Caddx gimbals (they are the same thing) incase you didn’t know why I’m talking about using them.

Just make sure you switch your UART TX over to the S-Bus/CRSF in port since they are different.

The XF/Caddx gimbal is not supported for mavlink control until version 4.7 of ardupilot. 4.7 is not an official release. I think 4.5.7 is the latest official so the directions you linked wont work for a bit still until they get merged in to the official ardupilot.

The s-bus servo option works great if you just want RC control otherwise you will need to update your flight controller to the release candidate version of ardupilot/arducopter.
