- ##### 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_MMC_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 MMC and eMMC cards devices.
- It is used as follows:
- (#)Initialize the SDMMC low level resources by implement the HAL_MMC_MspInit() API:
- (##) Enable the SDMMC interface clock using __HAL_RCC_SDMMC_CLK_ENABLE();
- (##) SDMMC pins configuration for MMC 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_MMC_ReadBlocks_DMA()
- and HAL_MMC_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 function 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_MMC_ENABLE_IT()
- and __HAL_MMC_DISABLE_IT() inside the communication process.

- (#) At this stage, you can perform MMC read/write/erase operations after MMC card initialization
- *** MMC Card Initialization and configuration ***
- ================================================
- [..]
- To initialize the MMC Card, use the HAL_MMC_Init() function. It Initializes
- SDMMC Peripheral (STM32 side) and the MMC Card, and put it into StandBy State (Ready for data transfer).
- This function provide the following operations:
- (#) Initialize the SDMMC 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 MMC 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 MMC 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 MMC card. The API used is HAL_MMC_InitCard().
- This phase allows the card initialization and identification
- and check the MMC Card type (Standard Capacity or High Capacity)
- The initialization flow is compatible with MMC standard.
- This API (HAL_MMC_InitCard()) could be used also to reinitialize the card in case
- of plug-off plug-in.
- (#) Configure the MMC Card Data transfer frequency. By Default, the card transfer
- frequency by adjusting the "ClockDiv" field.
- In transfer mode and according to the MMC Card standard, make sure that the
- SDMMC_CK frequency doesn't exceed 25MHz and 100MHz in High-speed mode switch.
- (#) Select the corresponding MMC Card according to the address read with the step 2.
- (#) Configure the MMC Card in wide bus mode: 4-bits data.
- *** MMC Card Read operation ***
- ==============================
- [..]
- (+) You can read from MMC card in polling mode by using function HAL_MMC_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_MMC_GetCardState() function for MMC card state.
- (+) You can read from MMC card in DMA mode by using function HAL_MMC_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_MMC_GetCardState() function for MMC card state.
- You could also check the DMA transfer process through the MMC Rx interrupt event.
- (+) You can read from MMC card in Interrupt mode by using function HAL_MMC_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_MMC_GetCardState() function for MMC card state.
- You could also check the IT transfer process through the MMC Rx interrupt event.
- *** MMC Card Write operation ***
- ===============================
- [..]
- (+) You can write to MMC card in polling mode by using function HAL_MMC_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_MMC_GetCardState() function for MMC card state.
- (+) You can write to MMC card in DMA mode by using function HAL_MMC_WriteBlocks_DMA().
- This function support only 512-bytes 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 ensure that the transfer is done correctly. The check is done
- through HAL_MMC_GetCardState() function for MMC card state.
- You could also check the DMA transfer process through the MMC Tx interrupt event.
- (+) You can write to MMC card in Interrupt mode by using function HAL_MMC_WriteBlocks_IT().

- through HAL_MMC_GetCardState() function for MMC card state.
- You could also check the IT transfer process through the MMC Tx interrupt event.
- *** MMC card information ***
- ===========================
- [..]
- (+) To get MMC card information, you can use the function HAL_MMC_GetCardInfo().
- It returns useful information about the MMC card such as block size, card type,
- block number ...
- *** MMC card CSD register ***
- ============================
- [..]
- (+) The HAL_MMC_GetCardCSD() API allows to get the parameters of the CSD register.
- Some of the CSD parameters are useful for card initialization and identification.
- *** MMC card CID register ***
- ============================
- [..]
- (+) The HAL_MMC_GetCardCID() API allows to get the parameters of the CID register.
- Some of the CID parameters are useful for card initialization and identification.
- *** MMC HAL driver macros list ***
- ==================================
- [..]
- Below the list of most used macros in MMC HAL driver.
- (+) __HAL_MMC_ENABLE : Enable the MMC device

- [..]
- (@) You can refer to the MMC HAL driver header file for more useful macros
- *** Callback registration ***
- =============================================
- [..]
- The compilation define USE_HAL_MMC_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
- Use Functions HAL_MMC_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 : MMC MspInit.
- (+) MspDeInitCallback : MMC MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
- Use function HAL_MMC_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 : MMC MspInit.
- (+) MspDeInitCallback : MMC MspDeInit.
- This function) takes as parameters the HAL peripheral handle and the Callback ID.
- By default, after the HAL_MMC_Init and if the state is HAL_MMC_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_MMC_Init
- and HAL_MMC_DeInit only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the HAL_MMC_Init and HAL_MMC_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_MMC_RegisterCallback before calling HAL_MMC_DeInit
- or HAL_MMC_Init function.
- When The compilation define USE_HAL_MMC_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.
