Thanks Rud for your posts / blog entry. Helped me out allot! This may be a stupid question but how do i get azimuth value returned from getOrientation to go 0 - 360 degrees rather -180 to 180 degrees? Is there something i'm missing? Im using code very similar to the code you posted on your blog, but im using the java math.todegrees() function to convert from radians and have no digital filter implemented.
Tend to miss out vital bits of code when working in the early hours of the morning!
