Digital Photo Camera Triggering (using a GPIO pin)
This module controls triggering of an attached external digital camera via one or more GPIO pins for on/off/shoot/zoom.
It can trigger photos based on GPS distance, time or circle radius in both fixedwings and rotorcraft.

Trigger Digital Camera (I2C).
Using I2C connected remote microcontroller
Digital Photo Camera Triggering (using a I2C channel)
This module controls triggering of an attached device via an I2C command.
Typically a remote microcontroller (atmega/arduino) will then use the triggering/zoom/power commands.
Using the PAYLOAD_COMMAND, all functions of the camera can be controlled.
It can trigger photos based on GPS distance, time or circle radius in both fixedwings and rotorcraft.

Digital Camera Triggering over UART link.
Send attitude and other relevant data to a computer based photocamera after a shootphoto command is given. And in return get certain value back from the computerbased photocamera to be able to intercat with the flightplan.</description>
Digital Photo Camera Triggering (using a UART link)
This module controls triggering of an attached external digital camera via UART commands.
It can trigger photos based on GPS distance, time or circle radius in both fixedwings and rotorcraft.
This module fullfilss 4 functions:
1) send shoot commands over UART
2) Besides triggering the shooting of images, the module also sends attitude and other relevant data.
Typically an external linux camera or linux computer will receive the attitude and position data and add
it to the photos.
3) The module will also parse the replies received over the UART. This contains status but can also
contain computer vision results to able to interact with the flightplan.
4) Finally, the module will also relay over telemetry all data it receives from the attached computer
or camera using the PAYLOAD message. This can for instance be used to downlink thumbnails.
The linux program used to parse the UART command is given in the subdirectory.

Digital Camera Triggering of an embedded camera on a linux based autopilot.
Digital Photo Camera Triggering (using embedded video)
This module controls triggering of an embedded digital camera on a linux based autopilot. This particular version triggers the video_rtp_stream.xml module to store jpeg images.
It can trigger photos based on GPS distance, time or circle radius in both fixedwings and rotorcraft.
