Odd Headings using HiTechnic Compass

Postby Axlle » Wed Feb 27, 2008 2:51 am

I just got a new HiTechnic Compass sensor yesterday and am having some problems using it. The compass doesnt read 0 and 180 degrees across form each other but it does read 90 and 270 in a straight line. I dont know if this has to do with calibrating it properly. I calibrated it once using 2 rotations and far from EM objects.

Has anyone else had this problem?

Even the slightest deviation from the horizontal alignment can introduce errors as big as 15-20 degrees, so you should make sure it’s not tilted in any way.
