43<p>Constructor.</p><p>Initialize with the <a href="../../../../nn/hid/CTR/Initialize.html"><CODE>nn::hid::CTR::Initialize</CODE></a> function before creating an instance.</p><p>This function calls the <CODE><a href="../../../../nn/hid/CTR/GyroscopeReader/Reset.html">Reset</a></CODE> function. For more information about the initial state after creation, see the <CODE><a href="../../../../nn/hid/CTR/GyroscopeReader/Reset.html">Reset</a></CODE> function. <br /><B>Note:</B> In some cases immediately after creation of the first instance, as much as 160 ms is required to attain stability before the application can start sampling. Please take note of this.&nbsp;</p><p>The class stores an instance of <CODE><a href="../../../../nn/hid/CTR/AccelerometerReader/Overview.html">AccelerometerReader</a></CODE>. The lifespan of that instance is the same as the lifespan of <CODE>GyroscopeReader</CODE>. In other words, <CODE>AccelerometerReader</CODE> instances are created or destroyed when <CODE>GyroscopeReader</CODE> instances are created or destroyed.</p><!-- write here --></div>
