+ @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 __HAL_RCC_SDIO_CLK_ENABLE();
+ (##) SDIO pins configuration for SD card
+ (+++) Enable the clock for the SDIO GPIOs using the functions __HAL_RCC_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 __HAL_RCC_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_ENABLE_IT()
+ and __HAL_SD_DISABLE_IT() inside the communication process.
+ (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
+ and __HAL_SD_CLEAR_IT()
+ (##) NVIC configuration if you need to use interrupt process (HAL_SD_ReadBlocks_IT()
+ and HAL_SD_WriteBlocks_IT() APIs).
+ (+++) Configure the SDIO interrupt priorities using function
+ HAL_NVIC_SetPriority();
+ (+++) Enable the NVIC SDIO IRQs using function HAL_NVIC_EnableIRQ()
+ (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT()
+ and __HAL_SD_DISABLE_IT() inside the communication process.
+ (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
+ and __HAL_SD_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
+ SDIO IP(STM32 side) and the SD Card, and put it into StandBy State (Ready for data transfer).
+ This function provide the following operations:
+
+ (#) Initialize the SDIO peripheral interface with defaullt configuration.
+ The initialization process is done at 400KHz. 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.
+
+ This phase of initialization is done through SDIO_Init() and
+ SDIO_PowerState_ON() SDIO low level APIs.
+
+ (#) Initialize the SD card. The API used is HAL_SD_InitCard().
+ This phase allows the card initialization and identification
+ and check the SD Card type (Standard Capacity or High Capacity)
+ The initialization flow is compatible with SD standard.
+
+ This API (HAL_SD_InitCard()) could be used also to reinitialize the card in case
+ of plug-off plug-in.
+
+ (#) Configure the SD Card Data transfer frequency. By Default, the card transfer
+ frequency is set to 24MHz. You can change or adapt this frequency by adjusting
+ the "ClockDiv" field.
+ 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 allows the read of 512 bytes blocks.
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_SD_GetCardState() function for SD card state.
+
+ (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
+ This function allows the read of 512 bytes blocks.
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_SD_GetCardState() function for SD card state.
+ You could also check the DMA transfer process through the SD Rx interrupt event.
+
+ (+) You can read from SD card in Interrupt mode by using function HAL_SD_ReadBlocks_IT().
+ This function allows the read of 512 bytes blocks.
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_SD_GetCardState() function for SD card state.
+ You could also check the IT transfer process through the SD Rx interrupt event.
+
+ *** SD Card Write operation ***
+ ===============================
+ [..]
+ (+) You can write to SD card in polling mode by using function HAL_SD_WriteBlocks().
+ This function allows the read of 512 bytes blocks.
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_SD_GetCardState() function for SD card state.
+
+ (+) You can write to SD card in DMA mode by using function HAL_SD_WriteBlocks_DMA().
+ This function allows the read of 512 bytes blocks.
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_SD_GetCardState() function for SD card state.
+ You could also check the DMA transfer process through the SD Tx interrupt event.
+
+ (+) You can write to SD card in Interrupt mode by using function HAL_SD_WriteBlocks_IT().
+ This function allows the read of 512 bytes blocks.
+ You can choose either one block read operation or multiple block read operation
+ by adjusting the "NumberOfBlocks" parameter.
+ After this, you have to ensure that the transfer is done correctly. The check is done
+ through HAL_SD_GetCardState() function for SD card state.
+ You could also check the IT transfer process through the SD Tx interrupt event.
+
+ *** SD card status ***
+ ======================
+ [..]
+ (+) The SD Status contains status bits that are related to the SD Memory
+ Card proprietary features. To get SD card status use the HAL_SD_GetCardStatus().
+
+ *** SD card information ***
+ ===========================
+ [..]
+ (+) To get SD card information, you can use the function HAL_SD_GetCardInfo().
+ It returns useful information about the SD card such as block size, card type,
+ block number ...
+
+ *** SD card CSD register ***
+ ============================
+ [..]
+ (+) The HAL_SD_GetCardCSD() API allows to get the parameters of the CSD register.
+ Some of the CSD parameters are useful for card initialization and identification.
+
+ *** SD card CID register ***
+ ============================
+ [..]
+ (+) The HAL_SD_GetCardCID() API allows to get the parameters of the CID register.
+ Some of the CSD parameters are useful for card initialization and identification.
+
+ *** SD HAL driver macros list ***
+ ==================================
+ [..]
+ Below the list of most used macros in SD HAL driver.
+
+ (+) __HAL_SD_ENABLE : Enable the SD device
+ (+) __HAL_SD_DISABLE : Disable the SD device
+ (+) __HAL_SD_DMA_ENABLE: Enable the SDIO DMA transfer
