Release Notes for STM32H745I-DISCO BSP Driver

Copyright © 2019 STMicroelectronics

Purpose

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.

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.

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.

Update History

Main Changes

  • Update STM32H745I-DISCO BSP driver to support new Touch Screen component GT911.
  • Apply general code Artistic Style fixes.

Main Changes

  • Align the defined symbol “SDRAM_DEVICE_SIZE” with value defined in memory datasheet.
  • Invert argument order between definitions and declarations of I2C4_WriteReg() and I2C4_ReadReg().

Main Changes

  • All source files: update disclaimer to add reference to the new license agreement.
  • 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.
  • Cache maintained operation is included in the BSP_LCD_FillRGBRect() function to solve the display issue when USE_DMA2D_TO_FILL_RGB_RECT is enabled.
  • Update the stack size for the FatFs_Shared_Device application.

Main Changes

  • Add explicit definition of “BSP_QSPI_Erase_t” type with 8KB, 64KB and 128KB erase size
    • Notes:
      • The STM32H745I-DISCO comes with a dual flash QSPI, the erase size for each flash is 4KB, 32KB and 64KB
      • From BSP top view these two flash are seen as a single one with twice the size
  • Minor typo fixes in comments

Dependencies

  • Components/common v7.0.0

Main Changes

  • Fix typo in BSP_PB_Init API implementation regarding EXTI button NVIC priority setting
  • Add License.md file

Dependencies

Main Changes

  • Rename GUI_Drv_t into UTILS_LCD_Drv_t

Backward Compatibility

  • This version breaks the compatibility with previous versions

Dependencies

  • Components/common v7.0.0

Main Changes

  • First official release of STM32H745I-DISCO BSP drivers in line with STM32Cube BSP drivers development guidelines (UM2298)
