<p><span style="font-weight: bold;">STMCube is an STMicroelectronics
original initiative to ease developers life by reducing development
efforts, time and cost.</span></p>
<p>STM32Cube covers STM32 portfolio.</p>
<p>STM32Cube Version 1.x includes:</p>
<ul>
<li><p>The STM32CubeMX, a graphical software configuration tool that
allows to generate C initialization code using graphical
wizards.</p></li>
<li><p>A comprehensive embedded software platform, delivered per series
(such as STM32CubeH5 for STM32H5 series)</p>
<ul>
<li><p>The STM32Cube HAL, an STM32 abstraction layer embedded software,
ensuring maximized portability across STM32 portfolio</p></li>
<li><p>A consistent set of middleware components such as RTOS, USB,
TCP/IP, Graphics]</p></li>
<li><p>A full set of software projects (basic examples, applications,
and demonstrations) for each board provided for this STM32
series.</p></li>
</ul></li>
</ul>
<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>Both the HAL and LL APIs are production–ready, checked with Coverity®
static analysis tool, and developed in compliance with MISRA C®
guidelines, following a process certified according to IEC 61508
systematic capability 2 level (SC2). Reports are available on
demand.</p>
