I'd be interested in other peoples experiences with this sensor.
I'm using a MEGA with the Adafruit code for magcompass. It sits atop a large Meccano robot - so lots of metal and motor magnetic fields! A standard non electronic compass works OK in this position. I only need heading data - no inclination. Now, with the compass used to measure heading using the x and y axis,results are all over the place. However, reorientating the compass to use z and x axis, results are pretty good. Anyone else experienced this and why?
