57<h2>Description</h2>
58    <div class="section">
59<p>Converts the raw sampling data from the accelerometers into acceleration values (in g's).</p><p>
60This converts exactly <CODE>bufLen</CODE> number of data items in <CODE>pSamplingData</CODE> to <CODE>pAcceleration</CODE>, so if the <CODE>pSamplingData</CODE> array is smaller than <CODE>bufLen</CODE>, this results in access beyond the bounds of the <CODE>pSamplingData</CODE> array.
61            </p><p>
62Make sure to allocate the <CODE>pSamplingData</CODE> array to be at least <CODE>bufLen</CODE> items long.
