+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ This driver implements a high level communication layer for read and write from/to
+ this memory. The needed STM32 hardware resources (SDIO and GPIO) are performed by
+ the user in HAL_SD_MspInit() function (MSP layer).
+ Basically, the MSP layer configuration should be the same as we provide in the
+ examples.
+ You can easily tailor this configuration according to hardware resources.
+
+ [..]
+ This driver is a generic layered driver for SDIO memories which uses the HAL
+ SDIO driver functions to interface with SD and uSD cards devices.
+ It is used as follows:
+
+ (#)Initialize the SDIO low level resources by implement the HAL_SD_MspInit() API:
+ (##) Enable the SDIO interface clock using __SDIO_CLK_ENABLE();
+ (##) SDIO pins configuration for SD card
+ (+++) Enable the clock for the SDIO GPIOs using the functions __GPIOx_CLK_ENABLE();
+ (+++) Configure these SDIO pins as alternate function pull-up using HAL_GPIO_Init()
+ and according to your pin assignment;
+ (##) DMA Configuration if you need to use DMA process (HAL_SD_ReadBlocks_DMA()
+ and HAL_SD_WriteBlocks_DMA() APIs).
+ (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE();
+ (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled.
+ (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
+ (+++) Configure the SDIO and DMA interrupt priorities using functions
+ HAL_NVIC_SetPriority(); DMA priority is superior to SDIO's priority
+ (+++) Enable the NVIC DMA and SDIO IRQs using function HAL_NVIC_EnableIRQ()
+ (+++) SDIO interrupts are managed using the macros __HAL_SD_SDIO_ENABLE_IT()
+ and __HAL_SD_SDIO_DISABLE_IT() inside the communication process.
+ (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_SDIO_GET_IT()
+ and __HAL_SD_SDIO_CLEAR_IT()
+ (#) At this stage, you can perform SD read/write/erase operations after SD card initialization
+
+
+ *** SD Card Initialization and configuration ***
+ ================================================
+ [..]
+ To initialize the SD Card, use the HAL_SD_Init() function. It Initializes
+ the SD Card and put it into StandBy State (Ready for data transfer).
+ This function provide the following operations:
+
+ (#) Apply the SD Card initialization process at 400KHz and check the SD Card
+ type (Standard Capacity or High Capacity). You can change or adapt this
+ frequency by adjusting the "ClockDiv" field.
+ The SD Card frequency (SDIO_CK) is computed as follows:
+
+ SDIO_CK = SDIOCLK / (ClockDiv + 2)
+
+ In initialization mode and according to the SD Card standard,
+ make sure that the SDIO_CK frequency doesn't exceed 400KHz.
+
+ (#) Get the SD CID and CSD data. All these information are managed by the SDCardInfo
+ structure. This structure provide also ready computed SD Card capacity
+ and Block size.
+
+ -@- These information are stored in SD handle structure in case of future use.
+
+ (#) Configure the SD Card Data transfer frequency. By Default, the card transfer
+ frequency is set to 48MHz / (SDIO_TRANSFER_CLK_DIV + 2) = 8MHz. You can change or adapt this frequency by adjusting
+ the "ClockDiv" field.
+ The SD Card frequency (SDIO_CK) is computed as follows:
+
+ SDIO_CK = SDIOCLK / (ClockDiv + 2)
+
+ In transfer mode and according to the SD Card standard, make sure that the
+ SDIO_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
+ To be able to use a frequency higher than 24MHz, you should use the SDIO
+ peripheral in bypass mode. Refer to the corresponding reference manual
+ for more details.
+
+ (#) Select the corresponding SD Card according to the address read with the step 2.
+
+ (#) Configure the SD Card in wide bus mode: 4-bits data.
+
+ *** SD Card Read operation ***
+ ==============================
+ [..]
+ (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks().
+ This function support only 512-byte block length (the block size should be
+ chosen as 512 byte).
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+
+ (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
+ This function support only 512-byte block length (the block size should be
+ chosen as 512 byte).
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to call the function HAL_SD_CheckReadOperation(), to insure
+ that the read transfer is done correctly in both DMA and SD sides.
+
+ *** SD Card Write operation ***
+ ===============================
+ [..]
+ (+) You can write to SD card in polling mode by using function HAL_SD_WriteBlocks().
+ This function support only 512-byte block length (the block size should be
+ chosen as 512 byte).
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+
+ (+) You can write to SD card in DMA mode by using function HAL_SD_WriteBlocks_DMA().
+ This function support only 512-byte block length (the block size should be
+ chosen as 512 byte).
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to call the function HAL_SD_CheckWriteOperation(), to insure
+ that the write transfer is done correctly in both DMA and SD sides.
+
+ *** SD card status ***
+ ======================
+ [..]
+ (+) At any time, you can check the SD Card status and get the SD card state
+ by using the HAL_SD_GetStatus() function. This function checks first if the
+ SD card is still connected and then get the internal SD Card transfer state.
+ (+) You can also get the SD card SD Status register by using the HAL_SD_SendSDStatus()
+ function.
+
+ *** SD HAL driver macros list ***
+ ==================================
+ [..]
+ Below the list of most used macros in SD HAL driver.
+
+ (+) __HAL_SD_SDIO_ENABLE : Enable the SD device
+ (+) __HAL_SD_SDIO_DISABLE : Disable the SD device
+ (+) __HAL_SD_SDIO_DMA_ENABLE: Enable the SDIO DMA transfer
+ (+) __HAL_SD_SDIO_DMA_DISABLE: Disable the SDIO DMA transfer
+ (+) __HAL_SD_SDIO_ENABLE_IT: Enable the SD device interrupt
+ (+) __HAL_SD_SDIO_DISABLE_IT: Disable the SD device interrupt
+ (+) __HAL_SD_SDIO_GET_FLAG:Check whether the specified SD flag is set or not
+ (+) __HAL_SD_SDIO_CLEAR_FLAG: Clear the SD's pending flags
+
+ (@) You can refer to the SD HAL driver header file for more useful macros
