17 ##### How to use this driver #####
18 ==============================================================================
19 [..]
20 This driver implements a high level communication layer for read and write from/to
21 this memory. The needed STM32 hardware resources (SDMMC and GPIO) are performed by
22 the user in HAL_SD_MspInit() function (MSP layer).
23 Basically, the MSP layer configuration should be the same as we provide in the
24 examples.
25 You can easily tailor this configuration according to hardware resources.
26
27 [..]
28 This driver is a generic layered driver for SDMMC memories which uses the HAL
29 SDMMC driver functions to interface with SD and uSD cards devices.
30 It is used as follows:
31
32 (#)Initialize the SDMMC low level resources by implement the HAL_SD_MspInit() API:
33 (##) Enable the SDMMC interface clock using __HAL_RCC_SDMMC_CLK_ENABLE();
34 (##) SDMMC pins configuration for SD card
35 (+++) Enable the clock for the SDMMC GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
36 (+++) Configure these SDMMC pins as alternate function pull-up using HAL_GPIO_Init()
37 and according to your pin assignment;
38 (##) DMA Configuration if you need to use DMA process (HAL_SD_ReadBlocks_DMA()
39 and HAL_SD_WriteBlocks_DMA() APIs).
40 (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE();
41 (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled.
42 (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
43 (+++) Configure the SDMMC and DMA interrupt priorities using functions
44 HAL_NVIC_SetPriority(); DMA priority is superior to SDMMC's priority
45 (+++) Enable the NVIC DMA and SDMMC IRQs using function HAL_NVIC_EnableIRQ()
46 (+++) SDMMC interrupts are managed using the macros __HAL_SD_ENABLE_IT()
47 and __HAL_SD_DISABLE_IT() inside the communication process.
48 (+++) SDMMC interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
49 and __HAL_SD_CLEAR_IT()
50 (##) NVIC configuration if you need to use interrupt process (HAL_SD_ReadBlocks_IT()
51 and HAL_SD_WriteBlocks_IT() APIs).
52 (+++) Configure the SDMMC interrupt priorities using function
53 HAL_NVIC_SetPriority();
54 (+++) Enable the NVIC SDMMC IRQs using function HAL_NVIC_EnableIRQ()
55 (+++) SDMMC interrupts are managed using the macros __HAL_SD_ENABLE_IT()
56 and __HAL_SD_DISABLE_IT() inside the communication process.
57 (+++) SDMMC interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
58 and __HAL_SD_CLEAR_IT()
59 (#) At this stage, you can perform SD read/write/erase operations after SD card initialization
60
61
62 *** SD Card Initialization and configuration ***
63 ================================================
64 [..]
65 To initialize the SD Card, use the HAL_SD_Init() function. It Initializes
66 SDMMC IP (STM32 side) and the SD Card, and put it into StandBy State (Ready for data transfer).
67 This function provide the following operations:
68
69 (#) Initialize the SDMMC peripheral interface with defaullt configuration.
70 The initialization process is done at 400KHz. You can change or adapt
71 this frequency by adjusting the "ClockDiv" field.
72 The SD Card frequency (SDMMC_CK) is computed as follows:
73
74 SDMMC_CK = SDMMCCLK / (ClockDiv + 2)
75
76 In initialization mode and according to the SD Card standard,
77 make sure that the SDMMC_CK frequency doesn't exceed 400KHz.
78
79 This phase of initialization is done through SDMMC_Init() and
80 SDMMC_PowerState_ON() SDMMC low level APIs.
81
82 (#) Initialize the SD card. The API used is HAL_SD_InitCard().
83 This phase allows the card initialization and identification
84 and check the SD Card type (Standard Capacity or High Capacity)
85 The initialization flow is compatible with SD standard.
86
87 This API (HAL_SD_InitCard()) could be used also to reinitialize the card in case
88 of plug-off plug-in.
89
90 (#) Configure the SD Card Data transfer frequency. By Default, the card transfer
91 frequency is set to 24MHz. You can change or adapt this frequency by adjusting
92 the "ClockDiv" field.
93 In transfer mode and according to the SD Card standard, make sure that the
94 SDMMC_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
95 To be able to use a frequency higher than 24MHz, you should use the SDMMC
96 peripheral in bypass mode. Refer to the corresponding reference manual
97 for more details.
98
99 (#) Select the corresponding SD Card according to the address read with the step 2.
100
101 (#) Configure the SD Card in wide bus mode: 4-bits data.
102
103 *** SD Card Read operation ***
104 ==============================
105 [..]
106 (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks().
107 This function allows the read of 512 bytes blocks.
108 You can choose either one block read operation or multiple block read operation
109 by adjusting the "NumberOfBlocks" parameter.
110 After this, you have to ensure that the transfer is done correctly. The check is done
111 through HAL_SD_GetCardState() function for SD card state.
112
113 (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
114 This function allows the read of 512 bytes blocks.
115 You can choose either one block read operation or multiple block read operation
116 by adjusting the "NumberOfBlocks" parameter.
117 After this, you have to ensure that the transfer is done correctly. The check is done
118 through HAL_SD_GetCardState() function for SD card state.
119 You could also check the DMA transfer process through the SD Rx interrupt event.
120
121 (+) You can read from SD card in Interrupt mode by using function HAL_SD_ReadBlocks_IT().
122 This function allows the read of 512 bytes blocks.
123 You can choose either one block read operation or multiple block read operation
124 by adjusting the "NumberOfBlocks" parameter.
125 After this, you have to ensure that the transfer is done correctly. The check is done
126 through HAL_SD_GetCardState() function for SD card state.
127 You could also check the IT transfer process through the SD Rx interrupt event.
128

135 by adjusting the "NumberOfBlocks" parameter.
136 After this, you have to ensure that the transfer is done correctly. The check is done
137 through HAL_SD_GetCardState() function for SD card state.
138

140 This function allows the read of 512 bytes blocks.
141 You can choose either one block read operation or multiple block read operation
142 by adjusting the "NumberOfBlocks" parameter.
143 After this, you have to ensure that the transfer is done correctly. The check is done
144 through HAL_SD_GetCardState() function for SD card state.
145 You could also check the DMA transfer process through the SD Tx interrupt event.
146
147 (+) You can write to SD card in Interrupt mode by using function HAL_SD_WriteBlocks_IT().
148 This function allows the read of 512 bytes blocks.
149 You can choose either one block read operation or multiple block read operation

152 through HAL_SD_GetCardState() function for SD card state.
153 You could also check the IT transfer process through the SD Tx interrupt event.
154
155 *** SD card status ***
156 ======================
157 [..]
158 (+) The SD Status contains status bits that are related to the SD Memory
159 Card proprietary features. To get SD card status use the HAL_SD_GetCardStatus().
160
161 *** SD card information ***
162 ===========================
163 [..]
164 (+) To get SD card information, you can use the function HAL_SD_GetCardInfo().
