  26.                         ##### How to use this driver #####
  27.   ==============================================================================
  28.   [..]
  29.     This driver implements a high level communication layer for read and write from/to
  30.     this memory. The needed STM32 hardware resources (SDIO and GPIO) are performed by
  31.     the user in HAL_SD_MspInit() function (MSP layer).
  32.     Basically, the MSP layer configuration should be the same as we provide in the
  33.     examples.
  34.     You can easily tailor this configuration according to hardware resources.
  35.  
  36.   [..]
  37.     This driver is a generic layered driver for SDIO memories which uses the HAL
  38.     SDIO driver functions to interface with SD and uSD cards devices.
  39.     It is used as follows:
  40.  
  41.     (#)Initialize the SDIO low level resources by implementing the HAL_SD_MspInit() API:
  42.         (##) Enable the SDIO interface clock using __HAL_RCC_SDIO_CLK_ENABLE();
  43.         (##) SDIO pins configuration for SD card
  44.             (+++) Enable the clock for the SDIO GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
  45.             (+++) Configure these SDIO pins as alternate function pull-up using HAL_GPIO_Init()
  46.                   and according to your pin assignment;
  47.         (##) DMA configuration if you need to use DMA process (HAL_SD_ReadBlocks_DMA()
  48.              and HAL_SD_WriteBlocks_DMA() APIs).
  49.             (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE();
  50.             (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled.
  51.         (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
  52.             (+++) Configure the SDIO and DMA interrupt priorities using functions
  53.                   HAL_NVIC_SetPriority(); DMA priority is superior to SDIO's priority
  54.             (+++) Enable the NVIC DMA and SDIO IRQs using function HAL_NVIC_EnableIRQ()
  55.             (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT()
  56.                   and __HAL_SD_DISABLE_IT() inside the communication process.
  57.             (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
  58.                   and __HAL_SD_CLEAR_IT()
  59.         (##) NVIC configuration if you need to use interrupt process (HAL_SD_ReadBlocks_IT()
  60.              and HAL_SD_WriteBlocks_IT() APIs).
  61.             (+++) Configure the SDIO interrupt priorities using function HAL_NVIC_SetPriority();
  62.             (+++) Enable the NVIC SDIO IRQs using function HAL_NVIC_EnableIRQ()
  63.             (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT()
  64.                   and __HAL_SD_DISABLE_IT() inside the communication process.
  65.             (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
  66.                   and __HAL_SD_CLEAR_IT()
  67.     (#) At this stage, you can perform SD read/write/erase operations after SD card initialization
  68.  
  69.  
  70.   *** SD Card Initialization and configuration ***
  71.   ================================================
  72.   [..]
  73.     To initialize the SD Card, use the HAL_SD_Init() function. It Initializes
  74.     SDIO Peripheral(STM32 side) and the SD Card, and put it into StandBy State (Ready for data transfer).
  75.     This function provide the following operations:
  76.  
  77.     (#) Apply the SD Card initialization process at 400KHz and check the SD Card
  78.         type (Standard Capacity or High Capacity). You can change or adapt this
  79.         frequency by adjusting the "ClockDiv" field.
  80.         The SD Card frequency (SDIO_CK) is computed as follows:
  81.  
  82.            SDIO_CK = SDIOCLK / (ClockDiv + 2)
  83.  
  84.         In initialization mode and according to the SD Card standard,
  85.         make sure that the SDIO_CK frequency doesn't exceed 400KHz.
  86.  
  87.         This phase of initialization is done through SDIO_Init() and
  88.         SDIO_PowerState_ON() SDIO low level APIs.
  89.  
  90.     (#) Initialize the SD card. The API used is HAL_SD_InitCard().
  91.         This phase allows the card initialization and identification
  92.         and check the SD Card type (Standard Capacity or High Capacity)
  93.         The initialization flow is compatible with SD standard.
  94.  
  95.         This API (HAL_SD_InitCard()) could be used also to reinitialize the card in case
  96.         of plug-off plug-in.
  97.  
  98.     (#) Configure the SD Card Data transfer frequency. You can change or adapt this
  99.         frequency by adjusting the "ClockDiv" field.
  100.         In transfer mode and according to the SD Card standard, make sure that the
  101.         SDIO_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
  102.         To be able to use a frequency higher than 24MHz, you should use the SDIO
  103.         peripheral in bypass mode. Refer to the corresponding reference manual
  104.         for more details.
  105.  
  106.     (#) Select the corresponding SD Card according to the address read with the step 2.
  107.  
  108.     (#) Configure the SD Card in wide bus mode: 4-bits data.
  109.  
  110.   *** SD Card Read operation ***
  111.   ==============================
  112.   [..]
  113.     (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks().

  115.         chosen as 512 bytes).
  116.         You can choose either one block read operation or multiple block read operation
  117.         by adjusting the "NumberOfBlocks" parameter.
  118.         After this, you have to ensure that the transfer is done correctly. The check is done
  119.         through HAL_SD_GetCardState() function for SD card state.
  120.  
  121.     (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
  122.         This function support only 512-bytes block length (the block size should be
  123.         chosen as 512 bytes).
  124.         You can choose either one block read operation or multiple block read operation
  125.         by adjusting the "NumberOfBlocks" parameter.
  126.         After this, you have to ensure that the transfer is done correctly. The check is done
  127.         through HAL_SD_GetCardState() function for SD card state.

  167.  
  168.   *** SD card status ***
  169.   ======================
  170.   [..]
  171.     (+) The SD Status contains status bits that are related to the SD Memory
  172.         Card proprietary features. To get SD card status use the HAL_SD_GetCardStatus().
  173.  
  174.   *** SD card information ***

  196.     (+) __HAL_SD_ENABLE : Enable the SD device
  197.     (+) __HAL_SD_DISABLE : Disable the SD device
  198.     (+) __HAL_SD_DMA_ENABLE: Enable the SDIO DMA transfer
  199.     (+) __HAL_SD_DMA_DISABLE: Disable the SDIO DMA transfer
  200.     (+) __HAL_SD_ENABLE_IT: Enable the SD device interrupt
  201.     (+) __HAL_SD_DISABLE_IT: Disable the SD device interrupt
  202.     (+) __HAL_SD_GET_FLAG:Check whether the specified SD flag is set or not
  203.     (+) __HAL_SD_CLEAR_FLAG: Clear the SD's pending flags
  204.  
  205.     (@) You can refer to the SD HAL driver header file for more useful macros
  206.  
  207.   *** Callback registration ***
  208.   =============================================
  209.   [..]
  210.     The compilation define USE_HAL_SD_REGISTER_CALLBACKS when set to 1
  211.     allows the user to configure dynamically the driver callbacks.
  212.  
  213.     Use Functions HAL_SD_RegisterCallback() to register a user callback,
  214.     it allows to register following callbacks:
  215.       (+) TxCpltCallback : callback when a transmission transfer is completed.
  216.       (+) RxCpltCallback : callback when a reception transfer is completed.
  217.       (+) ErrorCallback : callback when error occurs.
  218.       (+) AbortCpltCallback : callback when abort is completed.
  219.       (+) MspInitCallback    : SD MspInit.
  220.       (+) MspDeInitCallback  : SD MspDeInit.
  221.     This function takes as parameters the HAL peripheral handle, the Callback ID
  222.     and a pointer to the user callback function.
  223.  
  224.     Use function HAL_SD_UnRegisterCallback() to reset a callback to the default
  225.     weak (surcharged) function. It allows to reset following callbacks:
  226.       (+) TxCpltCallback : callback when a transmission transfer is completed.
  227.       (+) RxCpltCallback : callback when a reception transfer is completed.
  228.       (+) ErrorCallback : callback when error occurs.
  229.       (+) AbortCpltCallback : callback when abort is completed.
  230.       (+) MspInitCallback    : SD MspInit.
  231.       (+) MspDeInitCallback  : SD MspDeInit.
  232.     This function) takes as parameters the HAL peripheral handle and the Callback ID.
  233.  
  234.     By default, after the HAL_SD_Init and if the state is HAL_SD_STATE_RESET
  235.     all callbacks are reset to the corresponding legacy weak (surcharged) functions.
  236.     Exception done for MspInit and MspDeInit callbacks that are respectively
  237.     reset to the legacy weak (surcharged) functions in the HAL_SD_Init
  238.     and  HAL_SD_DeInit only when these callbacks are null (not registered beforehand).
  239.     If not, MspInit or MspDeInit are not null, the HAL_SD_Init and HAL_SD_DeInit
  240.     keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
  241.  
  242.     Callbacks can be registered/unregistered in READY state only.
  243.     Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
  244.     in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
  245.     during the Init/DeInit.
  246.     In that case first register the MspInit/MspDeInit user callbacks
  247.     using HAL_SD_RegisterCallback before calling HAL_SD_DeInit
  248.     or HAL_SD_Init function.
  249.  
  250.     When The compilation define USE_HAL_SD_REGISTER_CALLBACKS is set to 0 or
  251.     not defined, the callback registering feature is not available
  252.     and weak (surcharged) callbacks are used.
