<h1 id="purpose">Purpose</h1>
<p>STM32WL series will serve all applications requiring Sub-GHz
(LoRaWAN, Sigfox) capabilities in a low-power context with an open dual
core architecture offer.</p>
<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
(such as STM32CubeWL for STM32WL series)
<ul>
<li>The STM32Cube HAL, an STM32 abstraction layer embedded software,
ensuring maximized portability across STM32 portfolio</li>
<li>A consistent set of middleware components such as RTOS, USB, TCP/IP,
Graphics, LoRaWAN, Sigfox</li>
</ul></li>
</ul>
<p>All embedded software utilities come 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><img src="_htmresc/STM32Cube_2020.bmp" /></p>
<p>The HAL (Hardware Abstraction Layer) & LL (Low Layers) drivers
provided within this package supports the following STM32WLxx
product:</p>
<ul>
<li>STM32WL55xx</li>
<li>STM32WL54xx</li>
<li>STM32WLE5xx</li>
<li>STM32WLE4xx</li>
<li>STM32WL5Mxx</li>
</ul>
<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>
<p>For quick getting started with the STM32CubeWL firmware package,
refer to UM2643 and you can download firmware updates and all the latest
documentation from www.st.com/stm32cubefw</p>
