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 (SDIO 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 SDIO memories which uses the HAL
29 SDIO driver functions to interface with SD and uSD cards devices.
30 It is used as follows:
31
32 (#)Initialize the SDIO low level resources by implement the HAL_SD_MspInit() API:
33 (##) Enable the SDIO interface clock using __SDIO_CLK_ENABLE();
34 (##) SDIO pins configuration for SD card
35 (+++) Enable the clock for the SDIO GPIOs using the functions __GPIOx_CLK_ENABLE();
36 (+++) Configure these SDIO 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 __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 SDIO and DMA interrupt priorities using functions
44 HAL_NVIC_SetPriority(); DMA priority is superior to SDIO's priority
45 (+++) Enable the NVIC DMA and SDIO IRQs using function HAL_NVIC_EnableIRQ()
46 (+++) SDIO interrupts are managed using the macros __HAL_SD_SDIO_ENABLE_IT()
47 and __HAL_SD_SDIO_DISABLE_IT() inside the communication process.
48 (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_SDIO_GET_IT()
49 and __HAL_SD_SDIO_CLEAR_IT()
50 (#) At this stage, you can perform SD read/write/erase operations after SD card initialization
51
52
53 *** SD Card Initialization and configuration ***
54 ================================================
55 [..]
56 To initialize the SD Card, use the HAL_SD_Init() function. It Initializes
57 the SD Card and put it into StandBy State (Ready for data transfer).
58 This function provide the following operations:
59
60 (#) Apply the SD Card initialization process at 400KHz and check the SD Card
61 type (Standard Capacity or High Capacity). You can change or adapt this
62 frequency by adjusting the "ClockDiv" field.
63 The SD Card frequency (SDIO_CK) is computed as follows:
64
65 SDIO_CK = SDIOCLK / (ClockDiv + 2)
66
67 In initialization mode and according to the SD Card standard,
68 make sure that the SDIO_CK frequency doesn't exceed 400KHz.
69
70 (#) Get the SD CID and CSD data. All these information are managed by the SDCardInfo
71 structure. This structure provide also ready computed SD Card capacity
72 and Block size.
73
74 -@- These information are stored in SD handle structure in case of future use.
75
76 (#) Configure the SD Card Data transfer frequency. By Default, the card transfer
77 frequency is set to 48MHz / (SDIO_TRANSFER_CLK_DIV + 2) = 8MHz. You can change or adapt this frequency by adjusting
78 the "ClockDiv" field.
79 The SD Card frequency (SDIO_CK) is computed as follows:
80
81 SDIO_CK = SDIOCLK / (ClockDiv + 2)
82
83 In transfer mode and according to the SD Card standard, make sure that the
84 SDIO_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
85 To be able to use a frequency higher than 24MHz, you should use the SDIO
86 peripheral in bypass mode. Refer to the corresponding reference manual
87 for more details.
88
89 (#) Select the corresponding SD Card according to the address read with the step 2.
90
91 (#) Configure the SD Card in wide bus mode: 4-bits data.
92
93 *** SD Card Read operation ***
94 ==============================
95 [..]
96 (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks().
97 This function support only 512-byte block length (the block size should be
98 chosen as 512 byte).
99 You can choose either one block read operation or multiple block read operation
100 by adjusting the "NumberOfBlocks" parameter.
101
102 (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
103 This function support only 512-byte block length (the block size should be
104 chosen as 512 byte).
105 You can choose either one block read operation or multiple block read operation
106 by adjusting the "NumberOfBlocks" parameter.
107 After this, you have to call the function HAL_SD_CheckReadOperation(), to insure
108 that the read transfer is done correctly in both DMA and SD sides.
109
110 *** SD Card Write operation ***
111 ===============================
112 [..]
113 (+) You can write to SD card in polling mode by using function HAL_SD_WriteBlocks().
114 This function support only 512-byte block length (the block size should be
115 chosen as 512 byte).
116 You can choose either one block read operation or multiple block read operation
117 by adjusting the "NumberOfBlocks" parameter.
118
119 (+) You can write to SD card in DMA mode by using function HAL_SD_WriteBlocks_DMA().
120 This function support only 512-byte block length (the block size should be
121 chosen as 512 byte).
122 You can choose either one block read operation or multiple block read operation
123 by adjusting the "NumberOfBlocks" parameter.
124 After this, you have to call the function HAL_SD_CheckWriteOperation(), to insure
125 that the write transfer is done correctly in both DMA and SD sides.
126
127 *** SD card status ***
128 ======================
129 [..]
130 (+) At any time, you can check the SD Card status and get the SD card state
131 by using the HAL_SD_GetStatus() function. This function checks first if the
132 SD card is still connected and then get the internal SD Card transfer state.
133 (+) You can also get the SD card SD Status register by using the HAL_SD_SendSDStatus()
134 function.
135
136 *** SD HAL driver macros list ***
137 ==================================
138 [..]
139 Below the list of most used macros in SD HAL driver.
140
141 (+) __HAL_SD_SDIO_ENABLE : Enable the SD device
142 (+) __HAL_SD_SDIO_DISABLE : Disable the SD device
143 (+) __HAL_SD_SDIO_DMA_ENABLE: Enable the SDIO DMA transfer
144 (+) __HAL_SD_SDIO_DMA_DISABLE: Disable the SDIO DMA transfer
145 (+) __HAL_SD_SDIO_ENABLE_IT: Enable the SD device interrupt
146 (+) __HAL_SD_SDIO_DISABLE_IT: Disable the SD device interrupt
147 (+) __HAL_SD_SDIO_GET_FLAG:Check whether the specified SD flag is set or not
148 (+) __HAL_SD_SDIO_CLEAR_FLAG: Clear the SD's pending flags
149
150 (@) You can refer to the SD HAL driver header file for more useful macros
