APM 2 ArduPlane relay and camera stabilization?

Posted by The Old Flyer on February 21, 2012 at 11:11am

I have made several successful APM 1 aerial survey flights.  (See http://diydrones.com/forum/topics/a-successful-apm-aerial-survey-mission)  

I am now ready to do the same missions with APM 2 but APM 2 has no relay. From the APM 2 wiki page, "No relay. Very few people used this, so if you want one (to trigger a camera, for instance), we support adding one externally."  How do we do that. There is no documentation showing how to control the pin marked, Camera Shutter.  (See issue 512.)

I think that every aerial photographer, aerial mapper, and aerial photo survey application (both aircraft and 'copter) would make good use of the relay.

Camera roll stabilization would be a big help for aerial surveys.  Can the Camera.pde from ArduCopter be added to AdruPlane?  Can the UserCode.pde and UserVariables.h file be added to the ArduPlane release?

Thanks to the development team for the great APM 1 flight controller system.

I am looking forward to taking advantage of the improvements that APM 2 offers.

    I added the Camera.pde (from ArduCopter 2.3) to AdruPlane 2.28 but there were compile errors.

    I added UserCode.pde and UserVariables.h and got no compile errors.

    I have not found the command sequence to address and/or control Camera Shutter A9.

    I have been able to command servo outpots 5 to 8 with the DO_SET_SERVO - # - PWM.

    I'll connect a servo/relay to servo #8 and control my camera with that for now.

    Hi, this is quite simple, if you look at the explanation of the wiki, has an output labeled (A9)of camera shutter, simply rolling out a servo switch as they do in the store 3DR, https://store.diydrones.com/ServoSwitch_V10_p/br-0007-01.htm
