I'm having a problem with the mission command DO_DIGICAM_CONTROL in APM:Copter V3.4.2-rc2. I can trigger the servo by pressing the "trigger camera now" button in mission planner "actions",but the command DO_DIGICAM_CONTROL in flight plan does not trigger the servo/camera. When I do the Trigger Camera Now in Mission Planner, it uses the command DO_DIGICAM_CONTROL, so I think the issue isn't in ArduPilot.when I write waypoints into UAV,a strange thing happened:
In mission planner/flight plan, I set param5=1(shutter_cmd) in command DO_DIGICAM_CONTROL,and I write waypoints(with DO_DIGICAM_CONTROL) by pressing the "write wps" button ,
after that,I press the "Read wps" button to confirm the mission,but the value of param5 in command DO_DIGICAM_CONTROL has changed,1.28E-05 as shown in the figure below.And DO_DIGICAM_CONTROL does not work while flying in auto mode.
