Angle measurement
The angle relative to gravity can be calculated directly in the EP1816-3008 (CoE 0x8080:1D).
However, the complex trigonometric calculations would have undue impact on the cycle time of the Box, so
that in this mode the angle resolution is limited to 1°.
In cases where higher resolution and accuracy is required, the calculations should be executed on a PC. The
sensors used are capable of an accuracy of less than 0.1°.
Since the angle values are derived from the acceleration values, which are subject to certain noise, they
have to be filtered via suitable algorithms.
In simple cases this could be moving average, for example.
