bcostm 6:e1d9da7fe856 7 * @brief This file includes the uSD card driver mounted on STM32746G-Discovery
bcostm 6:e1d9da7fe856 8 * board.
bcostm 6:e1d9da7fe856 9 @verbatim
bcostm 6:e1d9da7fe856 10 1. How To use this driver:
bcostm 6:e1d9da7fe856 11 --------------------------
bcostm 6:e1d9da7fe856 12 - This driver is used to drive the micro SD external card mounted on STM32746G-Discovery
bcostm 6:e1d9da7fe856 13 board.
bcostm 6:e1d9da7fe856 14 - This driver does not need a specific component driver for the micro SD device
bcostm 6:e1d9da7fe856 15 to be included with.
bcostm 6:e1d9da7fe856 16
bcostm 6:e1d9da7fe856 17 2. Driver description:
bcostm 6:e1d9da7fe856 18 ---------------------
bcostm 6:e1d9da7fe856 19 + Initialization steps:
bcostm 6:e1d9da7fe856 20 o Initialize the micro SD card using the BSP_SD_Init() function. This
bcostm 6:e1d9da7fe856 21 function includes the MSP layer hardware resources initialization and the
bcostm 6:e1d9da7fe856 22 SDIO interface configuration to interface with the external micro SD. It
bcostm 6:e1d9da7fe856 23 also includes the micro SD initialization sequence.
bcostm 6:e1d9da7fe856 24 o To check the SD card presence you can use the function BSP_SD_IsDetected() which
bcostm 6:e1d9da7fe856 25 returns the detection status
bcostm 6:e1d9da7fe856 26 o If SD presence detection interrupt mode is desired, you must configure the
bcostm 6:e1d9da7fe856 27 SD detection interrupt mode by calling the function BSP_SD_ITConfig(). The interrupt
bcostm 6:e1d9da7fe856 28 is generated as an external interrupt whenever the micro SD card is
bcostm 6:e1d9da7fe856 29 plugged/unplugged in/from the board.
bcostm 6:e1d9da7fe856 30 o The function BSP_SD_GetCardInfo() is used to get the micro SD card information
bcostm 6:e1d9da7fe856 31 which is stored in the structure "HAL_SD_CardInfoTypedef".
bcostm 6:e1d9da7fe856 32
bcostm 6:e1d9da7fe856 33 + Micro SD card operations
bcostm 6:e1d9da7fe856 34 o The micro SD card can be accessed with read/write block(s) operations once
bcostm 6:e1d9da7fe856 35 it is ready for access. The access can be performed whether using the polling
bcostm 6:e1d9da7fe856 36 mode by calling the functions BSP_SD_ReadBlocks()/BSP_SD_WriteBlocks(), or by DMA
bcostm 6:e1d9da7fe856 37 transfer using the functions BSP_SD_ReadBlocks_DMA()/BSP_SD_WriteBlocks_DMA()
bcostm 6:e1d9da7fe856 38 o The DMA transfer complete is used with interrupt mode. Once the SD transfer
bcostm 6:e1d9da7fe856 39 is complete, the SD interrupt is handled using the function BSP_SD_IRQHandler(),
bcostm 6:e1d9da7fe856 40 the DMA Tx/Rx transfer complete are handled using the functions
bcostm 6:e1d9da7fe856 41 BSP_SD_DMA_Tx_IRQHandler()/BSP_SD_DMA_Rx_IRQHandler(). The corresponding user callbacks
bcostm 6:e1d9da7fe856 42 are implemented by the user at application level.
bcostm 6:e1d9da7fe856 43 o The SD erase block(s) is performed using the function BSP_SD_Erase() with specifying
bcostm 6:e1d9da7fe856 44 the number of blocks to erase.
Jerome Coutant 8:56384bddaba5 45 o The SD runtime status is returned when calling the function BSP_SD_GetCardState().
