Except that they aren't sensitive enough to rotational acceleration for that. If that's what you want to do then you should be asking for one accel to be replaced with a 3-axis gyro and/or magnetometer. You might like a USB CAN bus adaptor too. _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
