This has the added benefit of saving 60 bytes and simplifying Mission Planner gui. Moved some code from RC_Channel_aux to AP_Mount class The servos get written by the update_mount_position() function, this simplifies main() PS: The beauty of using libraries: I did not have to touch a single line of ArduPlane's code!

|
|
* *
|
|
* Purpose: Move a 2 or 3 axis mount attached to vehicle, *
|
|
* Used for mount to track targets or stabilise *
|
|
* camera plus other modes. *
|
|
* *
|
|
* Usage: Use in main code to control mounts attached to *
|
|
* vehicle. *
|
|
* *
|
|
*Comments: All angles in degrees * 100, distances in meters*
|
|
* unless otherwise stated. *
