Or, better, use a 3-axis magnetometer instead of a gyro. At the time the FR was designed, gyros were significantly more expensive and less available than accelerometers, and magnetometers were large and even more expensive. Spaced accelerometers sounded like a good way of getting most of the way there while still being affordable. In practice it doesn't work so well. In the meantime gyro and magnetometer prices have tumbled. _______________________________________________ devel mailing list devel@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/devel
