Hello all,
Can anyone tell me or point me in the right direction if it is possible to programe the apm 2.5 to trigger a camera when it reaches a waypoint, i currently trigger the camera from my transmitter through the receiver but would like to automate this from the apm.
Many Thanks for any input.

I have the same question. I see the "camera trigger" function, but I don't know what functionality that provides.
Have you guys looked at the Flight Planner commands in the Mission Planner? Don't really need a relay for APM2 or 2.5 anymore.
If you use a servo to trigger your camera you can do a servo action.
CH 5 and CH 8 are used.
The command is MAV_CMD_DO_REPEAT_SERVO:
param1: 5 or 8
alt field: PWM output
lat field: the number of times to repeat
long field: The delay in seconds
I am currently grappling with this issue, but on an APM1, trying to use the relay.
When you generate a grid in MP it produces a nice array of waypoints, but how to trigger the camera at these waypoints is the question.
Currently I am experimenting with the "set relay" command with some success, but this is a now command, as distinct from a navigation command. It is unclear in the Wiki whether you have to change all the waypoints to do commands, except the path ends, where you will need to add extra do commands if you want a picture.
If anyone is aware of any descriptions of implementing a full picture taking grid, it would be appreciated.
I read something awhile back that the APM1 had a relay just for the camera trigger, although they removed it the APM2, There was a remark about still being able to setup a trigger the APM2.
There are lots's of outputs anyway so if they went through the trouble to name it for that I would not be surprised if there is a a corresponding option. This is all just speculation but it might give you a place to start, If you looked into the camera trigger feature in the APM1 Wiki
