MAVlink camera fix to point

Hi,

I have Pixhawk Copter 3.5.3 with Storm32 BGC connected with STorM32 serial protocol.
I would like to implement feature that camera will will be fixed to one GPS point.
I have found that I can use MAV_CMD_DO_MOUNT_CONTROL to control the camera and there is also parameter MAV_MOUNT_MODE_GPS_POINT. But I can not found any further information how to use it.

Thanks…

Do not use those messages. just use SET_ROI message.

Hi, but SET_ROI will set copter heading but not camera yaw, am I right ?

If you have a gimbal that can do YAW, and it is correctlly configured then:
SET_ROI will only move the gimbal, not the copter

If you have a gimbal that can NOT do YAW, and it is correctlly configured then:
SET_ROI will move the copter

OK, but how copter knows yaw is “correcty configured” ? Which parameter changes the behaviour ?

Make sure to set the MNT_TYPE parameter.
And you need to assign a servo output to the gimbal Pan function, if you have one. If you do not, then don’t.
