Does any of you have experience to install a BaseCam (AlexMos) SimpleBGC gimbal to the Pixhawk, or have the technical knowledge to inform me if this is possible?
More information about the brushless gimbal controller can be found here: http://www.basecamelectronics.com/simplebgc/
I used this gimbal in combination with DJI Naza V2. I assume the Pixhawk can be used as well to control the gimbal (if DJI can do it, Pixhawk should definitely be capable). The gimbal controller board will take care of stabilizing the 2-axis tilt & roll. I only want to be able to control the camera pitch. Is this possible?
Thanks for suggestions.
I'm using the gimbal ARRIS cm3000 (SimpleBCG32-Alexmos). I'm practice the wiki of ardupilot which is about gimbal connection --> (http://ardupilot.org/copter/docs/common-simplebgc-gimbal.html#commo...).
During the BaseCam SimpleBGC software setting all works fine about the frame follow mode (enabled for the yaw and disabled for the pitch and roll)…
than, when i connect to the "Telemetry2" port, the remote controll seem to be right about DO_MOUNT-CONTROL orientation (command of Mission Planner GCS for the yaw, pitch and roll gimbal orientation) but the problem is the inconsistence between the yaw reference angle of the gimbal that does not follow the frame yaw during the fly.... it should be ever the same...
I would be grateful if you could help me to understand how is possible that the gimbal works fine for the FOLLOW YAW exclusively when it is not connect to the Pixhawk. In fact just i connect on the "telemetry2" port of pixhawk the gimbal lost its follow mode for the yaw and keeps to point a wrong specific direction ( like pitch and roll)...
I'm deeply studing the wiki ardupilot, i'm searching about a parameter that enables the YAW FOLLOW MODE in ardupilot but nothing until now.
I know that ther is a Mavlink connection possibility (using different configuration and wiring) but I'd like to try with Alexmos first.
can somebody help me? every advice is very helpful..thank's lot.
I have nearly an identical set up. I can control my gimbal and shutter with my RC. And I can control the shutter on Auto missions. But I can't control the gimbal with the mission planner mount command. Have you tried that? Any success? I've been banging my head against the wall for at least a few days trying to figure out how to get the autopilot to control the gimbal. Thus far, no luck. I am using an AlexMos 8 bit controller. If you got it working. I'd love to know how.

Check out my video. It may help. I have manual control of the pitch of the gimbal and also use the FC to provide input.
Fixed mine by re-calibrating the radio, to include the ch-6 knob.
So, could someone help me figure out what's going on with my pitch from the Pixhawk? I'd love some help.
I want to do this too, but then i lose manual pitch control because the Pix will be using it to send to the Alexmos for stabilization....any other way around it so that I can still maintain pitch control?
I don't know what you mean? If you did what I did, it works like you say.
In my setup I use channels 9 and 10 for pitch and roll of the camera. I set the RC9_FUNCTION/RC10_FUNCTION to 7 and 8.
I use a spare channel on my s bus receiver to bypass the pixhawk to get the yaw axis. I set it up similar to the Tarot 2d gimbal in the wiki. It works well; see this video https://youtu.be/DCV9T7fFA1Y
My next goal is to add bank as the copter banks.
haha. That was easy. I just hit stabilize roll in the gimbal setup. Now the pixhawk tells the gimbal to bank as the copter banks. It is really reverse stabilization. The gimbal and the pixhawk are both generating similar stabilization results. The pixhawk's is adding to the bank, the gimbal is subtracting the bank. Together they have a pleasing damped cancellation. Result: The gopro banks with the heli.
Now let's try a flight test.
Instead of using the pitch control (output of an AUX channel on the PIX), simply select an open port on your RX and connect straight to the Alexmos board.
Or you can follow this Wiki:
The idea is the same, just different gimbal.
