MNT1_DEFLT_MODE set to 3
MNT1_TYPE set to 6 (if using telemetry 2)
RC10_OPTION (or any channel) set to 213 to control the Tilt axis
RC11_OPTION (or any channel) set to 214 to control the Pan axis
SERIAL_2_BAUD set to 115
CAM1_TYPE set to 2
CAM1_RELAY_ON set to 1
RELAY_PIN set to 50 (use the AUX 1 output to trigger the camera).
RC9_OPTION set to 9 (Trigger camera) (use the channel 9 in remote to trigger the camera).
Go to SETTING => CONTROL => MAVLINK
COM 2 set baudrate to 115200 (after setting it, please reboot).
Configure the autopilot by setting these parameters:
If using 4.5 (or earlier) only the 1st relay can be used so set RELAY_PIN
to the GPIO pin used
If using 4.6 (or higher) any relay can be used. Below are settings if the first relay is used.
Set SERVOx_FUNCTION
= -1 (GPIO) where “x” is the servo output channel used. This is not required in the rare case where an autopilot’s dedicated GPIO pins are used.
ArduPilot logs TRIG messages when it triggers the camera. If the camera provides a GPIO output (e.g. camera flash hotshoe) then this can be used to also log CAM messages at the exact moment that pictures are taken.
Set the following parameters:
Set SERVOx_FUNCTION = -1 (GPIO) where “x” is the servo output channel used. This is not required in the rare case where the autopilot’s dedicated GPIO pins are used.
Connect one of the autopilot’s GPIO pins to the camera or the camera control cable that accepts high/low voltage input. As mentioned on the the autopilot’s servo/motor outputs can normally be used but, in addition, some autopilots have dedicated pins purely for use as relays/GPIOs.
Set = 4 (Camera)
Set to the GPIO pin used
Set to the time (in seconds) that the relay is held high
Set = 0 to swap the relay voltage. E.g. GPIO output would now be normally high by default, and then low to trigger the camera shutter
Connect the camera’s GPIO output to one of the autopilot’s (e.g. AUX OUT). As mentioned above there are restrictions on which pins may be used.
Set to the pin number connected to the hotshoe.
Set = 0 if the hotshoe voltage goes low when a picture is taken or 1 if the voltage goes high.
