Hi,
I would lile to use the Survey function in mission planner which uses the CAM_TRIG_DIST method to trigger a camera at regular distance intervals.
I'm using an infrared camera trigger which is activated by a PWM signal (configurable).
The question is on the Pixhawk board, how do I configure the PWM output pin that is triggered by CAM_TRIG_DIST ? Is there a parameter somewhere or is it hardcoded to s specific pixhawk output port ?
Thx for quick help, I have to do some photogrammetey shoot tomorrow !

Thanks Aforsyth, this is the answer I needed.
As I use a NEX5 camera triggered by an IR device which is itself triggered by a PWM servo signal, I can thus use Cam_trigg_dist with pixhawk AUx1 (and mapping ch7 to this AUx1).
I'm impatient to try it out!
@hughes, I've read / followed your IR trigger setup instructions and myself have a Nex5 and Strattosnapper2 trigger. For some reason, the flight data servo commands "toggle" and "high" will trigger the camera just fine, but the "Trigger Camera NOW" right-click command and the DO_SET_CAM_TRIGG_DIST do not activate trigger. Any idea what I might be doing wrong?
@aforsyth Thanks for the link! Good to know!
The wiki does not mention that it is not working with Pixhawk.
But: "Stay tuned for a 3DR CHDK cable" . Any update on this?
Thanks for the link!
The problem is it all means more weight. This is why I like the simple solution for the APM. Camera control board sounds good. Some teaser 3DR?
