<h1 id="purpose">Purpose</h1>
<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 STM32CubeL0 for STM32L0 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, FatFS, STM32 TouchSensing Library]</p></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>

<ul>
<li>Add additional check on hi2c->hdmtx and hi2c->hdmarx before resetting DMA Tx/Rx complete callbacks</li>
</ul></li>
<li>Update Sequential transfer APIs to adjust xfermode condition.
<ul>
<li>Replace hi2c->XferCount < MAX_NBYTE_SIZE by hi2c->XferCount <= MAX_NBYTE_SIZE which corresponds to a case without reload</li>
