The unit is g (as in G-force). 1 G is roughly 9.8 m/s^2 (http://en.wikipedia.org/wiki/Standard_gravity) The accelerometer's manufacturers (ST Microelectronics) may know how to recalibrate the sensor, but they don't seem to be telling. It is calibrated at the factory and probably requires special equipment. I've heard some theories that differences in readings between devices may be because the N900's assembly process might be imprecise when installing the sensor, so that it is sometimes mounted at a slight angle inside the device. If so, the sensor itself is not at fault. The best you could do then is perhaps apply a configurable rotation matrix from inside the kernel driver, but the driver does not support such a thing yet. _______________________________________________ maemo-users mailing list maemo-users@xxxxxxxxx https://lists.maemo.org/mailman/listinfo/maemo-users
