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 serie.

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

  • stm32756g_eval_camera.c/.h:
    • Support ov5640 camera sensor
  • stm32756g_eval.c/.h:
    • Add OV5640 I2C address
    • Update CAMERA IO Read/Write to support ov5640 camera sensor
  • stm32756g_eval_nor.c:
    • Support MT28EW128ABA1LPC NOR Flash

Main Changes

  • stm32756g_eval_audio.c:
    • Aligned with PDM library v3.0.0

Dependencies

  • This version must be used with v3.0.0 of PDM library

Main Changes

  • stm32756g_eval_lcd.c:
    • Fix compilation errors with SW4STM32 toolchain.
  • stm32756g_eval.c:
    • Upgrade version to v2.0.2

Main Changes

  • Add general description of BSP drivers
  • Add Dependencies section
  • Support of PDSC

Main Changes

  • stm32756g_eval_sd.c/.h:
    • Update BSP SD APIs following new HAL SD drivers implementation
    • Fix BlockSize to 512 bytes
  • stm32756g_eval_ts.c/.h:
    • Update TS_INT_PIN define
  • stm32756g_eval_lcd.c/.h:
    • Update BSP_LCD_ReadPixel to read correctly ARGB8888 and RGB888 pixels
  • stm32756g_eval_qspi.c/.h:
    • QSPI write operation improvement
    • Update CS High Time

Backward compatibility

  • These BSP drivers break the compatibility with previous versions.

Dependencies

  • If FatFs is required, “FatFS R0.11 ST modified 20161223” must be used with this version of BSP drivers.

Main Changes

  • Update typos in drivers comments.

Main Changes

  • Update overall drivers by removing BSP_PPP_IRQHandler, BSP_PPP_DMA_TX_IRQHandler and BSP_PPP_DMA_RX_IRQHandler to avoid possible conflict when the same Handler is used by different IPs.
  • These Handlers should be defined by user at application level, inducing a break of compatibility versus V1.0.1 of the STM32756G-EVAL BSP drivers
  • Add new functions BSP_POTENTIOMETER_Init() and BSP_POTENTIOMETER_GetLevel()
  • Update NVIC priority configuration to the lowest priority 0x0F
  • stm32756g_eval_lcd.c: Add the following APIs:
    • BSP_LCD_SetTransparency_NoReload()
    • BSP_LCD_SetLayerAddress_NoReload()
    • BSP_LCD_SetColorKeying_NoReload()
    • BSP_LCD_ResetColorKeying_NoReload()
    • BSP_LCD_SetLayerWindow_NoReload()
    • BSP_LCD_SetLayerVisible_NoReload()
    • BSP_LCD_Reload()
  • stm32756g_eval_camera.c:
    • Update BSP_CAMERA_Suspend() and BSP_CAMERA_Resume() APIs to use HAL API HAL_DCMI_Suspend() and HAL_DCMI_Resume()

Main Changes

  • stm32756g_eval.c
    • Add AUDIO_IO_DeInit() function to be compatible with common version 4.0.0 or later

Main Changes

  • First official release of the STM32756G-EVAL and STM32746G-EVAL BSP drivers

Dependencies

  • STM32F7xx_HAL_Driver V1.2.0
  • BSP Common V4.0.1
  • PDM Library V2.0.1
