<h1 id="purpose">Purpose</h1>
<p><strong>STMCube is an STMicroelectronics original initiative to ease developers life by reducing development efforts, time and cost</strong>. 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><strong>A comprehensive embedded software platform, delivered per series (such as STM32CubeF0 for STM32F0 series)</strong></li>
<li><strong>The STM32Cube HAL, an STM32 abstraction layer embedded software, ensuring maximized portability across STM32 portfolio</strong></li>
<li><strong>A consistent set of middleware components such as RTOS, USB, TCP/IP, Graphics, FatFS</strong></li>
<li><p><strong>All embedded software utilities come with a full set of examples.</strong></p></li>
<li><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 <img src="_htmresc/STM32Cube_2020.bmp" alt="STM32Cube architecture" /></p></li>
</ul>
<p>The <strong>HAL (Hardware Abstraction Layer)</strong> drivers provided within this package <strong>supports</strong> the following <strong>STM32F030x4/x6/x8/xC, STM32F031x4/x6, STM32F051x4/x6/x8, STM32F070x6/xB, STM32F071x8/xB, STM32F042x4/x6, STM32F072x8/xB, STM32F091xC, STM32F038xx, STM32F048xx, STM32F058xx, STM32F078xx and STM32F098xx devices.</strong></p>
<ul>
<li>For <strong>quick getting started with the STM32CubeF0 firmware package</strong>, refer to <a href="Documentation/STM32CubeF0GettingStarted.pdf">UM1779</a> you can download firmware updates and all the latest documentation from <a href="https://www.st.com/en/embedded-software/stm32cube-mcu-mpu-packages.html?sc=stm32cubefw">www.st.com/stm32cubefw</a></li>
