3DR X8+ AutoPilot Camera Trigger

Posted by tom on March 14, 2016 at 4:40am

I have an X8-M and PixHawk.  Last year everything worked fine when I was flying autopilot missions and the camera would automatically take pictures.  This year I went to test it after doing software updates and the autopilot doesn’t take pictures.  I can trigger the camera manually from the transmitter by toggling the on/off switch (ch7).  I’m not sure if I changed a setting or maybe the software update changed a setting.  I have also tried setting CAM_TRIGG_DIST to 1 and walking around with the drone, and it does in fact take pictures.  I have the camera USB cable plugged into AUX6 on the PixHawk.  Here is all of my pertinent information:

 

Camera: Canon S100

                USB Trigger is set to ON in CHDK

 

Mission Planner: Version 1.3.37

APM: Copter V3.3.3

Parameters:

                CAM_TRIGG_DIST: 0

                CAM_TRIGG_TYPE: 1 (Relay)

                CH7_OPT: 9 (Camera Trigger)

                RELAY_PIN: 55 (PixHawk AUXOUT6)

    In case anyone else was experiencing this issue, it was because of Mission Planner.  When using Auto WP -> Survey (GRID) to make my mission, Mission Planner would only put in the last DO_SET_CAM_TRIGG_DIST command.  There should have been one at the beginning of the mission as well.  After I updated my Mission Planner to 1.3.37 this bug was corrected and both DO_SET_CAM_TRIGG_DIST commands are now there.
