26 ##### How to use this driver #####
27 ==============================================================================
28 [..]
29 This driver implements a high level communication layer for read and write from/to
30 this memory. The needed STM32 hardware resources (SDMMC and GPIO) are performed by
31 the user in HAL_SD_MspInit() function (MSP layer).
32 Basically, the MSP layer configuration should be the same as we provide in the
33 examples.
34 You can easily tailor this configuration according to hardware resources.
35
36 [..]
37 This driver is a generic layered driver for SDMMC memories which uses the HAL
38 SDMMC driver functions to interface with SD and uSD cards devices.
39 It is used as follows:
40
41 (#)Initialize the SDMMC low level resources by implementing the HAL_SD_MspInit() API:
42 (##) Enable the SDMMC interface clock using __HAL_RCC_SDMMC_CLK_ENABLE();
43 (##) SDMMC pins configuration for SD card
44 (+++) Enable the clock for the SDMMC GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
45 (+++) Configure these SDMMC pins as alternate function pull-up using HAL_GPIO_Init()
46 and according to your pin assignment;
47 (##) NVIC configuration if you need to use interrupt process (HAL_SD_ReadBlocks_IT()
48 and HAL_SD_WriteBlocks_IT() APIs).
49 (+++) Configure the SDMMC interrupt priorities using function HAL_NVIC_SetPriority();
50 (+++) Enable the NVIC SDMMC IRQs using function HAL_NVIC_EnableIRQ()
51 (+++) SDMMC interrupts are managed using the macros __HAL_SD_ENABLE_IT()
52 and __HAL_SD_DISABLE_IT() inside the communication process.
53 (+++) SDMMC interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
54 and __HAL_SD_CLEAR_IT()
55 (##) No general propose DMA Configuration is needed, an Internal DMA for SDMMC Peripheral are used.
56
57 (#) At this stage, you can perform SD read/write/erase operations after SD card initialization
58
59
60 *** SD Card Initialization and configuration ***
61 ================================================
62 [..]
63 To initialize the SD Card, use the HAL_SD_Init() function. It Initializes
64 SDMMC Peripheral(STM32 side) and the SD Card, and put it into StandBy State (Ready for data transfer).
65 This function provide the following operations:
66
67 (#) Apply the SD Card initialization process at 400KHz and check the SD Card
68 type (Standard Capacity or High Capacity). You can change or adapt this
69 frequency by adjusting the "ClockDiv" field.
70 The SD Card frequency (SDMMC_CK) is computed as follows:
71
72 SDMMC_CK = SDMMCCLK / (2 * ClockDiv)
73
74 In initialization mode and according to the SD Card standard,
75 make sure that the SDMMC_CK frequency doesn't exceed 400KHz.
76
77 This phase of initialization is done through SDMMC_Init() and
78 SDMMC_PowerState_ON() SDMMC low level APIs.
79
80 (#) Initialize the SD card. The API used is HAL_SD_InitCard().
81 This phase allows the card initialization and identification
82 and check the SD Card type (Standard Capacity or High Capacity)
83 The initialization flow is compatible with SD standard.
84
85 This API (HAL_SD_InitCard()) could be used also to reinitialize the card in case
86 of plug-off plug-in.
87
88 (#) Configure the SD Card Data transfer frequency. You can change or adapt this
89 frequency by adjusting the "ClockDiv" field.
90 In transfer mode and according to the SD Card standard, make sure that the
91 SDMMC_CK frequency doesn't exceed 25MHz and 100MHz in High-speed mode switch.
92
93 (#) Select the corresponding SD Card according to the address read with the step 2.
94
95 (#) Configure the SD Card in wide bus mode: 4-bits data.
96
97 *** SD Card Read operation ***
98 ==============================
99 [..]
100 (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks().
101 This function support only 512-bytes block length (the block size should be
102 chosen as 512 bytes).
103 You can choose either one block read operation or multiple block read operation
104 by adjusting the "NumberOfBlocks" parameter.
105 After this, you have to ensure that the transfer is done correctly. The check is done
106 through HAL_SD_GetCardState() function for SD card state.
107
108 (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
109 This function support only 512-bytes block length (the block size should be
110 chosen as 512 bytes).
111 You can choose either one block read operation or multiple block read operation
112 by adjusting the "NumberOfBlocks" parameter.
113 After this, you have to ensure that the transfer is done correctly. The check is done
114 through HAL_SD_GetCardState() function for SD card state.
115 You could also check the DMA transfer process through the SD Rx interrupt event.
116
117 (+) You can read from SD card in Interrupt mode by using function HAL_SD_ReadBlocks_IT().
118 This function support only 512-bytes block length (the block size should be
119 chosen as 512 bytes).
120 You can choose either one block read operation or multiple block read operation
121 by adjusting the "NumberOfBlocks" parameter.
122 After this, you have to ensure that the transfer is done correctly. The check is done
123 through HAL_SD_GetCardState() function for SD card state.
124 You could also check the IT transfer process through the SD Rx interrupt event.
125

131 chosen as 512 bytes).
132 You can choose either one block read operation or multiple block read operation
133 by adjusting the "NumberOfBlocks" parameter.
134 After this, you have to ensure that the transfer is done correctly. The check is done
135 through HAL_SD_GetCardState() function for SD card state.

141 by adjusting the "NumberOfBlocks" parameter.
142 After this, you have to ensure that the transfer is done correctly. The check is done
143 through HAL_SD_GetCardState() function for SD card state.
144 You could also check the DMA transfer process through the SD Tx interrupt event.
145
146 (+) You can write to SD card in Interrupt mode by using function HAL_SD_WriteBlocks_IT().

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().

179 ==================================
180 [..]
181 Below the list of most used macros in SD HAL driver.
182
183 (+) __HAL_SD_ENABLE_IT: Enable the SD device interrupt
184 (+) __HAL_SD_DISABLE_IT: Disable the SD device interrupt
185 (+) __HAL_SD_GET_FLAG:Check whether the specified SD flag is set or not
186 (+) __HAL_SD_CLEAR_FLAG: Clear the SD's pending flags
187
188 (@) You can refer to the SD HAL driver header file for more useful macros
189
190 *** Callback registration ***
191 =============================================
192 [..]
193 The compilation define USE_HAL_SD_REGISTER_CALLBACKS when set to 1
194 allows the user to configure dynamically the driver callbacks.
195
196 Use Functions HAL_SD_RegisterCallback() to register a user callback,
197 it allows to register following callbacks:
198 (+) TxCpltCallback : callback when a transmission transfer is completed.
199 (+) RxCpltCallback : callback when a reception transfer is completed.
200 (+) ErrorCallback : callback when error occurs.
201 (+) AbortCpltCallback : callback when abort is completed.
202 (+) Read_DMADblBuf0CpltCallback : callback when the DMA reception of first buffer is completed.
203 (+) Read_DMADblBuf1CpltCallback : callback when the DMA reception of second buffer is completed.
204 (+) Write_DMADblBuf0CpltCallback : callback when the DMA transmission of first buffer is completed.
205 (+) Write_DMADblBuf1CpltCallback : callback when the DMA transmission of second buffer is completed.
206 (+) MspInitCallback : SD MspInit.
207 (+) MspDeInitCallback : SD MspDeInit.
208 This function takes as parameters the HAL peripheral handle, the Callback ID
209 and a pointer to the user callback function.
210 For specific callbacks TransceiverCallback use dedicated register callbacks:
211 respectively HAL_SD_RegisterTransceiverCallback().
212
213 Use function HAL_SD_UnRegisterCallback() to reset a callback to the default
214 weak (surcharged) function. It allows to reset following callbacks:
215 (+) TxCpltCallback : callback when a transmission transfer is completed.
216 (+) RxCpltCallback : callback when a reception transfer is completed.
217 (+) ErrorCallback : callback when error occurs.
218 (+) AbortCpltCallback : callback when abort is completed.
219 (+) Read_DMADblBuf0CpltCallback : callback when the DMA reception of first buffer is completed.
220 (+) Read_DMADblBuf1CpltCallback : callback when the DMA reception of second buffer is completed.
221 (+) Write_DMADblBuf0CpltCallback : callback when the DMA transmission of first buffer is completed.
222 (+) Write_DMADblBuf1CpltCallback : callback when the DMA transmission of second buffer is completed.
223 (+) MspInitCallback : SD MspInit.
224 (+) MspDeInitCallback : SD MspDeInit.
225 This function) takes as parameters the HAL peripheral handle and the Callback ID.
226 For specific callbacks TransceiverCallback use dedicated unregister callbacks:
227 respectively HAL_SD_UnRegisterTransceiverCallback().
228
229 By default, after the HAL_SD_Init and if the state is HAL_SD_STATE_RESET
230 all callbacks are reset to the corresponding legacy weak (surcharged) functions.
231 Exception done for MspInit and MspDeInit callbacks that are respectively
232 reset to the legacy weak (surcharged) functions in the HAL_SD_Init
233 and HAL_SD_DeInit only when these callbacks are null (not registered beforehand).
234 If not, MspInit or MspDeInit are not null, the HAL_SD_Init and HAL_SD_DeInit
235 keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
236
237 Callbacks can be registered/unregistered in READY state only.
238 Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
239 in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
240 during the Init/DeInit.
241 In that case first register the MspInit/MspDeInit user callbacks
242 using HAL_SD_RegisterCallback before calling HAL_SD_DeInit
243 or HAL_SD_Init function.
244
245 When The compilation define USE_HAL_SD_REGISTER_CALLBACKS is set to 0 or
246 not defined, the callback registering feature is not available
247 and weak (surcharged) callbacks are used.
