Understanding acceleration data

The measured acceleration data are sent into OUTX, OUTY and OUTZ registers. The

acceleration values are expressed as a 2’s complement number. When the full-scale is set

to 2g, each LSB corresponds to 18mg.

The table below provides few basic examples of the data that will be read in the data

registers when the device is subject to a given acceleration. The values listed in the table

are given under the hypothesis of perfect device calibration (i.e no offset, no gain error, ....)

and rounded to the closest integer.
