<h1 id="purpose">Purpose</h1>
<p><strong>STM32Cube is an STMicroelectronics original initiative to ease developers life by reducing development efforts, time and cost.</mark></strong></p>
<p>STM32Cube covers STM32 portfolio.</p>
<p>STM32Cube Version 1.x includes:</p>
<ul>
<li>The STM32CubeMX, a graphical software configuration tool that allows to generate C initialization code using graphical wizards.</li>
<li>A comprehensive embedded software platform, delivered per series
<ul>
<li>The STM32Cube HAL, an STM32 abstraction layer embedded software, ensuring maximized portability across STM32 portfolio.</li>
<li>Low-layer APIs (LL) offering a fast light-weight expert-oriented layer which is closer to the hardware than the HAL.</li>
<li>A consistent set of middleware libraries such as ThreadX, USBX…</li>
</ul></li>
</ul>
<p>All embedded software utilities, delivered with a full set of examples.</p>
<p>The STM32Cube firmware solution offers a straightforward API with a modular architecture, making it simple to fine tune custom applications and scalable to fit most requirements.</p>

<p><br />
</p>
<p>The HAL (Hardware Abstraction Layer) &amp; LL (Low Layers) drivers provided within this package support the STM32N6xx lines.</p>
<p>The HAL and LL drivers provided within this package are compliant with MISRA-C:2012 guidelines, and have been reviewed with a static analysis tool to eliminate possible run-time errors. Reports are available on demand.</p>
