Pitch and Roll angel Computation

[john McDonald]

Hello,

I am working on a 3D compass I was just wondering if you can help me to point to a routine that calculates the Pitch and Roll angel please.  I also appreciate if you could show me the formula to calculate them as well.

Thanks in advance,

John.

You can find a lot of info about this subject by doing a Google search
for "tilt compensated compass". Here is a app. note from ST (via
Pololu) called 'Using LSM303DLH for a tilt compensated electronic
compass':

I've looked at it before and it seemed pretty informative.
