Particularly, the compass won't notice if the device spins around the north-south axis. Do it slowly, and the accelerometers may be too limited to notice. Of course, such a movement doesn't normally happen in a car. But you do want to notice if this happens to your plane . . .

little question about navigation board
hi, first of all, congrats for your work :) now my question: why to add two more gyroscope sensors (so now we have 4 of them in our FR O_O) and not just merge a compass to the pressure sensor seen on the wiki (and it has also temperature)? I'm not informed on this topic, so I'm sorry if this question looks stupid :P kind regards -- ALFA21 IS PROVIDED AS IS AND WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

(and it has also temperature)? The pressur sensor needs to measure the ambient temperature to deliver accurate results. The temperature sensor is integrated and can be read using my driver.
