Connecting and controlling high-end gimbals through PPM/SBUS/CANbus via pixhawk

I have been searching high and low (I believe) for information on how to connect an control high end gimbals for DSLR cameras that only support PPM/SBUS/Canbus etc. for example: https://www.gremsy.com/gremsy-h7

I need to be able to control the gimbal FROM the pixhawk not just passthrough from the remote control.

Any pointers are welcome.

Thanks, Peter

Truly high end would speak mavlink, check out http://ardupilot.org/copter/docs/common-storm32-gimbal.html
I agree. However if available gimbals only provide the above: PPM/SBUS etc. is there a way to achieve that?

Hi

No answers to the issue but i need to join in as i have exactly the same problem.

I have a pixhawk powered X8 controlled via a gruapner 8 channel TX'r. I now also have a Gremsy H3 gimbal that will need a PPM input and this appears to mean 2 transmitters.

But, i also want to fire the shutter on a Nikon D90 DSLR. I could do this via the Graupner/pixhawk and a passthough channel but that means the camera shutter is controlled by a different person to the one controlling the gimbal. This is not ideal .

Are there connection options i am not considering here by any chance ?

Should be fairly easy. Just uncheck stabilize. Check documentation http://ardupilot.org/copter/docs/common-camera-gimbal.html
Enable sbus out, should be straight forward
Very interesting Andre.

I am upgrading the servo gimbal on my Groundhog hexacopter, which requires the gimbal angles to be both controlled by software and ideally interrogated (via Dronekit.)

Do you think the Storm32 might be the way to go?

Cheers

Greetings Keith,
Besides the 2x transmitter control option, did you find an alternative solution to control the Gremsy H3 with Pixhawk? I am currently using Pixhawk 2.1 Cube with Intel Edison.

Many Thanks,

Dave

Hi Dave

No i have not.  A pixhawk 2.1 ( or 3 ?) is the most likely solution.And even then probably not. I considered a 16 channel radio for a few minutes at least ! No matter how many channels you have there are still only 2 joystick controls so camera/Gimbal control is still the issue.

I guess you could build a custom radio tray and hack slide controls to some joystick gimbal wiring and achieve a 3 or 4 joystick solution. Then even if it worked you have the issue of can you deal with the requirements of controlling everything safely.

This is 2 seperate problems in one though, Gimbal via ppm/sbus and the single person to put it all into safe use.

Any update on This? I have a Gremsy T3 and a pixhawk 2.1 to do some experiements with. Anyone have any ideas on how to start? Gremsy claims https://www.youtube.com/watch?v=HmxGn0dA2bk will control via Mavlink. I am not sure what you would do to set this up? Any ideas??

I am able to control a Tarot T4-3D GoPro gimbal with a Pixhawk 1 via the S.Bus and I don't see any reason why it should not work with the Gremsy and Pixhawk 2.1 the same way. The S.Bus out of my receiver is connected to the RCIN of the Pixhawk and the S.Bus of the Pix is connected to the S.Bus of the gimbal. I've uploaded a diagram.
