ganlikun	0:13413ea9a877	18	==============================================================================
ganlikun	0:13413ea9a877	19	[..]
ganlikun	0:13413ea9a877	20	This driver implements a high level communication layer for read and write from/to
ganlikun	0:13413ea9a877	21	this memory. The needed STM32 hardware resources (SDMMC and GPIO) are performed by
ganlikun	0:13413ea9a877	22	the user in HAL_MMC_MspInit() function (MSP layer).
ganlikun	0:13413ea9a877	23	Basically, the MSP layer configuration should be the same as we provide in the
ganlikun	0:13413ea9a877	24	examples.
ganlikun	0:13413ea9a877	25	You can easily tailor this configuration according to hardware resources.
ganlikun	0:13413ea9a877	26
ganlikun	0:13413ea9a877	27	[..]
ganlikun	0:13413ea9a877	28	This driver is a generic layered driver for SDMMC memories which uses the HAL
ganlikun	0:13413ea9a877	29	SDMMC driver functions to interface with MMC and eMMC cards devices.
ganlikun	0:13413ea9a877	30	It is used as follows:
ganlikun	0:13413ea9a877	31
ganlikun	0:13413ea9a877	32	(#)Initialize the SDMMC low level resources by implement the HAL_MMC_MspInit() API:
ganlikun	0:13413ea9a877	33	(##) Enable the SDMMC interface clock using __HAL_RCC_SDMMC_CLK_ENABLE();
ganlikun	0:13413ea9a877	34	(##) SDMMC pins configuration for MMC card
ganlikun	0:13413ea9a877	35	(+++) Enable the clock for the SDMMC GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
ganlikun	0:13413ea9a877	36	(+++) Configure these SDMMC pins as alternate function pull-up using HAL_GPIO_Init()
ganlikun	0:13413ea9a877	37	and according to your pin assignment;
ganlikun	0:13413ea9a877	38	(##) DMA Configuration if you need to use DMA process (HAL_MMC_ReadBlocks_DMA()
ganlikun	0:13413ea9a877	39	and HAL_MMC_WriteBlocks_DMA() APIs).
ganlikun	0:13413ea9a877	40	(+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE();
ganlikun	0:13413ea9a877	41	(+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled.
ganlikun	0:13413ea9a877	42	(##) NVIC configuration if you need to use interrupt process when using DMA transfer.
ganlikun	0:13413ea9a877	43	(+++) Configure the SDMMC and DMA interrupt priorities using functions
ganlikun	0:13413ea9a877	44	HAL_NVIC_SetPriority(); DMA priority is superior to SDMMC's priority
ganlikun	0:13413ea9a877	45	(+++) Enable the NVIC DMA and SDMMC IRQs using function HAL_NVIC_EnableIRQ()
ganlikun	0:13413ea9a877	46	(+++) SDMMC interrupts are managed using the macros __HAL_MMC_ENABLE_IT()
ganlikun	0:13413ea9a877	47	and __HAL_MMC_DISABLE_IT() inside the communication process.
ganlikun	0:13413ea9a877	48	(+++) SDMMC interrupts pending bits are managed using the macros __HAL_MMC_GET_IT()

ganlikun	0:13413ea9a877	62	* MMC Card Initialization and configuration *
ganlikun	0:13413ea9a877	63	================================================
ganlikun	0:13413ea9a877	64	[..]
ganlikun	0:13413ea9a877	65	To initialize the MMC Card, use the HAL_MMC_Init() function. It Initializes
ganlikun	0:13413ea9a877	66	SDMMC IP (STM32 side) and the MMC Card, and put it into StandBy State (Ready for data transfer).
ganlikun	0:13413ea9a877	67	This function provide the following operations:
ganlikun	0:13413ea9a877	68
ganlikun	0:13413ea9a877	69	(#) Initialize the SDMMC peripheral interface with defaullt configuration.
ganlikun	0:13413ea9a877	70	The initialization process is done at 400KHz. You can change or adapt
ganlikun	0:13413ea9a877	71	this frequency by adjusting the "ClockDiv" field.
ganlikun	0:13413ea9a877	72	The MMC Card frequency (SDMMC_CK) is computed as follows:
ganlikun	0:13413ea9a877	73
ganlikun	0:13413ea9a877	74	SDMMC_CK = SDMMCCLK / (ClockDiv + 2)
ganlikun	0:13413ea9a877	75
ganlikun	0:13413ea9a877	76	In initialization mode and according to the MMC Card standard,
ganlikun	0:13413ea9a877	77	make sure that the SDMMC_CK frequency doesn't exceed 400KHz.
ganlikun	0:13413ea9a877	78
ganlikun	0:13413ea9a877	79	This phase of initialization is done through SDMMC_Init() and
ganlikun	0:13413ea9a877	80	SDMMC_PowerState_ON() SDMMC low level APIs.
ganlikun	0:13413ea9a877	81
ganlikun	0:13413ea9a877	82	(#) Initialize the MMC card. The API used is HAL_MMC_InitCard().
ganlikun	0:13413ea9a877	83	This phase allows the card initialization and identification
ganlikun	0:13413ea9a877	84	and check the MMC Card type (Standard Capacity or High Capacity)
ganlikun	0:13413ea9a877	85	The initialization flow is compatible with MMC standard.
ganlikun	0:13413ea9a877	86
ganlikun	0:13413ea9a877	87	This API (HAL_MMC_InitCard()) could be used also to reinitialize the card in case
ganlikun	0:13413ea9a877	88	of plug-off plug-in.
ganlikun	0:13413ea9a877	89
ganlikun	0:13413ea9a877	90	(#) Configure the MMC Card Data transfer frequency. By Default, the card transfer
ganlikun	0:13413ea9a877	91	frequency is set to 24MHz. You can change or adapt this frequency by adjusting
ganlikun	0:13413ea9a877	92	the "ClockDiv" field.
ganlikun	0:13413ea9a877	93	In transfer mode and according to the MMC Card standard, make sure that the
ganlikun	0:13413ea9a877	94	SDMMC_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
ganlikun	0:13413ea9a877	95	To be able to use a frequency higher than 24MHz, you should use the SDMMC
ganlikun	0:13413ea9a877	96	peripheral in bypass mode. Refer to the corresponding reference manual
ganlikun	0:13413ea9a877	97	for more details.
ganlikun	0:13413ea9a877	98
ganlikun	0:13413ea9a877	99	(#) Select the corresponding MMC Card according to the address read with the step 2.
ganlikun	0:13413ea9a877	100
