53<p>Reads sampling data from the gamepad, starting with the latest samples. Any previously loaded data is not read.</p><p>Use <a href="../../../../nn/hid/CTR/PadReader/SetStickClamp.html"><CODE>nn::hid::CTR::PadReader::SetStickClamp</CODE></a> to set the appropriate play in the analog stick because input occurs even if it is not touched. Note that it is not possible to obtain the maximum value between the input coordinate and the neutral position of the analog stick. This is because some rounding occurs during clamping. Do not use this maximum value for thresholds or the like.</p><!-- write here --></div>
