<h1 id="purpose">Purpose</h1>
<p>The BSP (Board Specific Package) drivers are parts of the STM32Cube package based on the HAL drivers and provide a set of high level APIs relative to the hardware components and features in the evaluation boards, discovery kits and nucleo boards coming with the STM32Cube package for a given STM32 series.</p>
<p>The BSP drivers allow a quick access to the boards’ services using high level APIs and without any specific configuration as the link with the HAL and the external components is done in intrinsic within the drivers.</p>
<p>From project settings points of view, user has only to add the necessary driver’s files in the workspace and call the needed functions from examples. However some low level configuration functions are weak and can be overridden by the applications if user wants to change some BSP drivers default behavior.</p>

<ul>
<li>All source files: update disclaimer to add reference to the new license agreement.</li>
<li>Modified the address calculation in the BSP_LCD_FillRGBRect() function when USE_DMA2D_TO_FILL_RGB_RECT is enabled to suppress the display of a distorted shape instead of a rectangle when trying to draw a rectangle with a bigger height.</li>

<h2 id="main-changes-5">Main Changes</h2>
<ul>
<li>BSP camera:
<ul>
<li>Update “BSP_CAMERA_DeInit” implementation to power down the camera instead of a full reset (allowing to save 120ms needed by the reset operation)</li>
</ul></li>
<li>BSP SD:
<ul>
<li>Update to add “USE_SD_BUS_WIDE_4B” configuration define allowing to specify if the SD card is intended to be interfaced with 4 data lanes
<ul>
<li>Notes:
<ul>
<li>when the “USE_SD_BUS_WIDE_4B” define is set to zero the SD is configured with 1 data lane allowing to overcome an issue with HW shared pins between the SD interface and the camera interface (if both camera and SD are needed)</li>
</ul></li>
</ul></li>
</ul></li>
<li>By default the “USE_SD_BUS_WIDE_4B” define is set to “1” to have the best SD performance</li>

<h2 id="main-changes-6">Main Changes</h2>
<ul>
<li>BSP QSPI: Add explicit definition of “BSP_QSPI_Erase_t” type with 8KB, 64KB and 128KB erase size
<ul>
<li>Notes:
<ul>
<li>The STM32H747I-DISCO comes with a dual flash QSPI, the erase size for each flash is 4KB, 32KB and 64KB</li>
<li>From BSP top view these two flash are seen as a single one with twice the size</li>
</ul></li>
</ul></li>
<li>BSP camera:
<ul>
<li>Apply HW reset after the initialization sequence for both OV9655 and OV5640 camera to fix potential noise issue</li>
</ul></li>
<li>BSP Joystick:
<ul>
<li>Fix “BSP_JOY_GetState” behavior by comparing the right joystick pin state (joystick pins are active high)</li>
<li>Add missing joystick interrupt priority defines to the “stm32h747i_discovery_conf_template.h” file
<ul>
<li>BSP_JOY1_SEL_IT_PRIORITY to BSP_JOY1_UP_IT_PRIORITY defines</li>
</ul></li>
</ul></li>
<li>BSP button:
<ul>
<li>Update the “stm32h747i_discovery_conf_template.h” file to rename the BSP_BUTTON_USER_IT_PRIORITY define to “BSP_BUTTON_WAKEUP_IT_PRIORITY” that is the right naming used withinb the driver</li>
