Jerome Coutant 0:146cf26a9bbb 22 User NOTES
Jerome Coutant 0:146cf26a9bbb 23 1. How To use this driver:
Jerome Coutant 0:146cf26a9bbb 24 --------------------------
Jerome Coutant 0:146cf26a9bbb 25 - This driver is used to drive the micro SD external card mounted on STM32412G-DISCOVERY
Jerome Coutant 0:146cf26a9bbb 26 board.
Jerome Coutant 0:146cf26a9bbb 27 - This driver does not need a specific component driver for the micro SD device
Jerome Coutant 0:146cf26a9bbb 28 to be included with.
Jerome Coutant 0:146cf26a9bbb 29
Jerome Coutant 0:146cf26a9bbb 30 2. Driver description:
Jerome Coutant 0:146cf26a9bbb 31 ---------------------
Jerome Coutant 0:146cf26a9bbb 32 + Initialization steps:
Jerome Coutant 0:146cf26a9bbb 33 o Initialize the micro SD card using the BSP_SD_Init() function. This
Jerome Coutant 0:146cf26a9bbb 34 function includes the MSP layer hardware resources initialization and the
Jerome Coutant 0:146cf26a9bbb 35 SDIO interface configuration to interface with the external micro SD. It
Jerome Coutant 0:146cf26a9bbb 36 also includes the micro SD initialization sequence.
Jerome Coutant 0:146cf26a9bbb 37 o To check the SD card presence you can use the function BSP_SD_IsDetected() which
Jerome Coutant 0:146cf26a9bbb 38 returns the detection status
Jerome Coutant 0:146cf26a9bbb 39 o If SD presence detection interrupt mode is desired, you must configure the
Jerome Coutant 0:146cf26a9bbb 40 SD detection interrupt mode by calling the function BSP_SD_ITConfig(). The interrupt
Jerome Coutant 0:146cf26a9bbb 41 is generated as an external interrupt whenever the micro SD card is
Jerome Coutant 0:146cf26a9bbb 42 plugged/unplugged in/from the board.
Jerome Coutant 0:146cf26a9bbb 43 o The function BSP_SD_GetCardInfo() is used to get the micro SD card information
Jerome Coutant 0:146cf26a9bbb 44 which is stored in the structure "HAL_SD_CardInfoTypedef".
Jerome Coutant 0:146cf26a9bbb 45
Jerome Coutant 0:146cf26a9bbb 46 + Micro SD card operations
Jerome Coutant 0:146cf26a9bbb 47 o The micro SD card can be accessed with read/write block(s) operations once
Jerome Coutant 0:146cf26a9bbb 48 it is ready for access. The access can be performed whether using the polling
Jerome Coutant 0:146cf26a9bbb 49 mode by calling the functions BSP_SD_ReadBlocks()/BSP_SD_WriteBlocks(), or by DMA
Jerome Coutant 0:146cf26a9bbb 50 transfer using the functions BSP_SD_ReadBlocks_DMA()/BSP_SD_WriteBlocks_DMA()
Jerome Coutant 0:146cf26a9bbb 51 o The DMA transfer complete is used with interrupt mode. Once the SD transfer
Jerome Coutant 0:146cf26a9bbb 52 is complete, the SD interrupt is handled using the function BSP_SD_IRQHandler(),
Jerome Coutant 0:146cf26a9bbb 53 the DMA Tx/Rx transfer complete are handled using the functions
Jerome Coutant 0:146cf26a9bbb 54 SD_DMA_Tx_IRQHandler()/SD_DMA_Rx_IRQHandler() that should be defined by user.
Jerome Coutant 0:146cf26a9bbb 55 The corresponding user callbacks are implemented by the user at application level.
Jerome Coutant 0:146cf26a9bbb 56 o The SD erase block(s) is performed using the function BSP_SD_Erase() with specifying
Jerome Coutant 0:146cf26a9bbb 57 the number of blocks to erase.
Jerome Coutant 0:146cf26a9bbb 58 o The SD runtime status is returned when calling the function BSP_SD_GetStatus().
