| ##### 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 (SDMMC 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 SDMMC memories which uses the HAL |
| SDMMC driver functions to interface with SD and uSD cards devices. |
| It is used as follows: |
| |
| (#)Initialize the SDMMC low level resources by implementing the HAL_SD_MspInit() API: |
| (##) Call the function HAL_RCCEx_PeriphCLKConfig with RCC_PERIPHCLK_SDMMC1 for |
| PeriphClockSelection and select SDMMC1 clock source (MSI, main PLL or PLLSAI1) |
| (##) Enable the SDMMC interface clock using __HAL_RCC_SDMMC1_CLK_ENABLE(); |
| (##) SDMMC pins configuration for SD card |
| (+++) Enable the clock for the SDMMC GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE(); |
| (+++) Configure these SDMMC pins as alternate function pull-up using HAL_GPIO_Init() |
| and according to your pin assignment; |
| (##) On STM32L4Rx/STM32L4Sxx devices, no DMA configuration is need, an internal DMA for SDMMC Peripheral is used. |
| (##) On other devices, perform 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 SDMMC and DMA interrupt priorities using functions |
| HAL_NVIC_SetPriority(); DMA priority is superior to SDMMC's priority |
| (+++) Enable the NVIC DMA and SDMMC IRQs using function HAL_NVIC_EnableIRQ() |
| (+++) SDMMC interrupts are managed using the macros __HAL_SD_ENABLE_IT() |
| and __HAL_SD_DISABLE_IT() inside the communication process. |
| (+++) SDMMC 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 SDMMC interrupt priorities using function HAL_NVIC_SetPriority(); |
| (+++) Enable the NVIC SDMMC IRQs using function HAL_NVIC_EnableIRQ() |
| (+++) SDMMC interrupts are managed using the macros __HAL_SD_ENABLE_IT() |
| and __HAL_SD_DISABLE_IT() inside the communication process. |
| (+++) SDMMC 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 |
| SDMMC Peripheral(STM32 side) and 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 (SDMMC_CK) is computed as follows: |
| |
| SDMMC_CK = SDMMCCLK / (2 * ClockDiv) on STM32L4Rx/STM32L4Sxx devices |
| SDMMC_CK = SDMMCCLK / (ClockDiv + 2) on other devices |
| |
| In initialization mode and according to the SD Card standard, |
| make sure that the SDMMC_CK frequency doesn't exceed 400KHz. |
| |
| This phase of initialization is done through SDMMC_Init() and |
| SDMMC_PowerState_ON() SDMMC 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. 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 |
| SDMMC_CK frequency doesn't exceed 25MHz and 100MHz in High-speed mode switch. |
| |
| (#) 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-bytes block length (the block size should be |
| chosen as 512 bytes). |
| 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 support only 512-bytes block length (the block size should be |
| chosen as 512 bytes). |
| 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 support only 512-bytes block length (the block size should be |

| 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 support only 512-bytes block length (the block size should be |
| chosen as 512 bytes). |
| 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 support only 512-bytes block length (the block size should be |
| chosen as 512 bytes). |

| 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 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 *** |

| ================================== |
| [..] |
| 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 SDMMC DMA transfer |
| (+) __HAL_SD_DMA_DISABLE: Disable the SDMMC DMA transfer |
| (+) __HAL_SD_ENABLE_IT: Enable the SD device interrupt |
| (+) __HAL_SD_DISABLE_IT: Disable the SD device interrupt |
| (+) __HAL_SD_GET_FLAG:Check whether the specified SD flag is set or not |
| (+) __HAL_SD_CLEAR_FLAG: Clear the SD's pending flags |
| |
| (@) You can refer to the SD HAL driver header file for more useful macros |
| |
| *** Callback registration *** |
| ============================================= |
| [..] |
| The compilation define USE_HAL_SD_REGISTER_CALLBACKS when set to 1 |
| allows the user to configure dynamically the driver callbacks. |
| |
| Use Functions HAL_SD_RegisterCallback() to register a user callback, |
| it allows to register following callbacks: |
| (+) TxCpltCallback : callback when a transmission transfer is completed. |
| (+) RxCpltCallback : callback when a reception transfer is completed. |
| (+) ErrorCallback : callback when error occurs. |
| (+) AbortCpltCallback : callback when abort is completed. |
| (+) Read_DMADblBuf0CpltCallback : callback when the DMA reception of first buffer is completed. |
| (+) Read_DMADblBuf1CpltCallback : callback when the DMA reception of second buffer is completed. |
| (+) Write_DMADblBuf0CpltCallback : callback when the DMA transmission of first buffer is completed. |
| (+) Write_DMADblBuf1CpltCallback : callback when the DMA transmission of second buffer is completed. |
| (+) MspInitCallback : SD MspInit. |
| (+) MspDeInitCallback : SD MspDeInit. |
| This function takes as parameters the HAL peripheral handle, the Callback ID |
| and a pointer to the user callback function. |
| For specific callbacks TransceiverCallback use dedicated register callbacks: |
| respectively HAL_SD_RegisterTransceiverCallback(). |
| |
| Use function HAL_SD_UnRegisterCallback() to reset a callback to the default |
| weak (surcharged) function. It allows to reset following callbacks: |
| (+) TxCpltCallback : callback when a transmission transfer is completed. |
| (+) RxCpltCallback : callback when a reception transfer is completed. |
| (+) ErrorCallback : callback when error occurs. |
| (+) AbortCpltCallback : callback when abort is completed. |
| (+) Read_DMADblBuf0CpltCallback : callback when the DMA reception of first buffer is completed. |
| (+) Read_DMADblBuf1CpltCallback : callback when the DMA reception of second buffer is completed. |
| (+) Write_DMADblBuf0CpltCallback : callback when the DMA transmission of first buffer is completed. |
| (+) Write_DMADblBuf1CpltCallback : callback when the DMA transmission of second buffer is completed. |
| (+) MspInitCallback : SD MspInit. |
| (+) MspDeInitCallback : SD MspDeInit. |
| This function) takes as parameters the HAL peripheral handle and the Callback ID. |
| For specific callbacks TransceiverCallback use dedicated unregister callbacks: |
| respectively HAL_SD_UnRegisterTransceiverCallback(). |
| |
| By default, after the HAL_SD_Init and if the state is HAL_SD_STATE_RESET |
| all callbacks are reset to the corresponding legacy weak (surcharged) functions. |
| Exception done for MspInit and MspDeInit callbacks that are respectively |
| reset to the legacy weak (surcharged) functions in the HAL_SD_Init |
| and HAL_SD_DeInit only when these callbacks are null (not registered beforehand). |
| If not, MspInit or MspDeInit are not null, the HAL_SD_Init and HAL_SD_DeInit |
| keep and use the user MspInit/MspDeInit callbacks (registered beforehand) |
| |
| Callbacks can be registered/unregistered in READY state only. |
| Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered |
| in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used |
| during the Init/DeInit. |
| In that case first register the MspInit/MspDeInit user callbacks |
| using HAL_SD_RegisterCallback before calling HAL_SD_DeInit |
| or HAL_SD_Init function. |
| |
| When The compilation define USE_HAL_SD_REGISTER_CALLBACKS is set to 0 or |
| not defined, the callback registering feature is not available |
| and weak (surcharged) callbacks are used. |
