I've set up my GoPro Hero 3's shutter to be activated by a Picoswitch (PWM controlled relay) and it works well. The Picoswitch is wired to RC10 on the Pixhawk servo rail.
I'd like to use a survey grid to trigger the GoPro using CAM_TRIGG_DIST so that Pixhawk logs GPS data every time the GoPro is triggered to take a picture.
My questions are:
Can a camera that is operated by PWM be used with the CAM_TRIGG_DIST option selected in the Survey Grid window's camera options tab, or does CAM_TRIGG_DIST only work for cameras that are operated by relay? (I have CAM_TRIGG_TYPE set to 0 for Servo)
If I can use CAM_TRIGG_DIST, what should my settings be for CH7_OPT and RC10_FUNCTION?
If I can use CAM_TRIGG_DIST, (and I select that option in the camera options tab of the survey grid window), do I need to specify SERVO, PWM, and CYCLE TIME?
Any help would be much appreciated - I battling frustration hard on my 11th trip to the school yard to try and make this work...
