Detailed Description

This file includes the uSD card driver mounted on STM32F769I-EVAL evaluation boards.

Author:

MCD Application Team

Version:

V2.0.1

Date:

06-April-2017

  How To use this driver:
  -----------------------
   - This driver is used to drive the micro SD external cards mounted on STM32F769I-EVAL
     evaluation board.
   - This driver does not need a specific component driver for the micro SD device
     to be included with.

  Driver description:
  ------------------
  + Initialization steps:
     o Initialize the micro SD card using the BSP_SD_InitEx() function. This 
       function includes the MSP layer hardware resources initialization and the
       SDIO interface configuration to interface with the external micro SD. It 
       also includes the micro SD initialization sequence for SDCard1 or SDCard2.
       When BSP_SD_Init() is called, SDCard1 is by default initialized.
     o To check the SD card presence you can use the function BSP_SD_IsDetectedEx() which 
       returns the detection status for SDCard1 or SDCard2.
       the function BSP_SD_IsDetected() returns the detection status for SDCard1.
     o If SD presence detection interrupt mode is desired, you must configure the 
       SD detection interrupt mode by calling the functions BSP_SD_ITConfig() for
       SDCard1 or BSP_SD_ITConfigEx() for SDCard2 . The interrupt is generated as 
       an external interrupt whenever the micro SD card is plugged/unplugged
       in/from the evaluation board. The SD detection is managed by MFX, so the 
       SD detection interrupt has to be treated by MFX_IRQOUT gpio pin IRQ handler.
     o The function BSP_SD_GetCardInfo()/BSP_SD_GetCardInfoEx() are used to get 
       the micro SD card information which is stored in the structure 
       "HAL_SD_CardInfoTypedef".

  + Micro SD card operations
     o The micro SD card can be accessed with read/write block(s) operations once 
       it is ready for access. The access, by default to SDCard1, can be performed whether 
       using the polling mode by calling the functions BSP_SD_ReadBlocks()/BSP_SD_WriteBlocks(),  
       or by DMA transfer using the functions BSP_SD_ReadBlocks_DMA()/BSP_SD_WriteBlocks_DMA().
       The access can be performed to SDCard1 or SDCard2 by calling BSP_SD_ReadBlocksEx(),
       BSP_SD_WriteBlocksEx() or by calling BSP_SD_ReadBlocks_DMAEx()/BSP_SD_WriteBlocks_DMAEx().
     o The DMA transfer complete is used with interrupt mode. Once the SD transfer
       is complete, the SD interrupt is handled using the function BSP_SDMMC1_IRQHandler()
       when SDCard1 is used or BSP_SDMMC2_IRQHandler() when SDCard2 is used.
       The DMA Tx/Rx transfer complete are handled using the functions
       BSP_SDMMC1_DMA_Tx_IRQHandler(), BSP_SDMMC1_DMA_Rx_IRQHandler(), 
       BSP_SDMMC2_DMA_Tx_IRQHandler(), BSP_SDMMC2_DMA_Rx_IRQHandler(). The corresponding
       user callbacks are implemented by the user at application level. 
     o The SD erase block(s) is performed using the functions BSP_SD_Erase()/BSP_SD_EraseEx() 
       with specifying the number of blocks to erase.
     o The SD runtime status is returned when calling the function BSP_SD_GetCardState()
       BSP_SD_GetCardStateEx().
