Gpio shutter (trigger) camera


I need some help to trigger my Camera.
I have a wifi camera (Sony QX100) and i can take a photo with a http command.

With Mission planner, I activated the trigger camera and it changes the GPIO14 value from 1100 to 1700 for 1 second.

I want to make a python script that detect that GPIO14 value to launch my http request

I can read the 8 RC inputs with ‘vehicle.channels’ but i didn’t find to know the values for the outputs…

Thx for your help

maybe dronekit can help you out with your issue?
this way you could also easily diversify the way/time you trigger your camera (waypoints, speed etc)
