Yaw angle calculation about z-axis.

[paresh3108]

Hi Kris
Personally i really found this code very useful for calibration and consequently to obtain the values.
However, I need your help in finding yaw angle about z-axis. In your code, it seems to be specified about x-axis. Can you please help me out?
Also do you have any good links to understand the relation between Eulerian and Quaternions angles.

Google "euler angles from quaternions", lots of links there. The Yaw is typically defined as rotation about the z-axis so I don't quite understand what you are asking for.

Thanks Kris for your reply,
But I mentioned it like that because in your code you said that:
Yaw is the angle between Sensor x-axis and Earth magnetic North
and I want you to find angle about z axis, I hope you are getting my problem now.

Yaw is angle made *between* x-axis and true North, changes in yaw so defines are rotations *about* the z-axis. So I still do not understand your question.

Thanks, No Problem
Anyways I got my solution after some edits
