annotate Discovery/Src/simulation.c @ 625:028d8f3a9410
Switch Sector / Scroll detection to vector implementation:
The vector implementation is mor robust against influences of roll and yaw to the pitch angle. To improve the performance the old sector based implementation has been replaced. In addition after entering focus state the roll angle is ignored.
To improve readability and due to removal of some no longer needed function codes, function names have been updated
