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 __HAL_RCC_SDIO_CLK_ENABLE();
|
---|
34 | (##) SDIO pins configuration for SD card
|
---|
35 | (+++) Enable the clock for the SDIO GPIOs using the functions __HAL_RCC_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 __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 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 24MHz. You can change or adapt this frequency by adjusting
|
---|
78 | the "ClockDiv" field.
|
---|
79 | In transfer mode and according to the SD Card standard, make sure that the
|
---|
80 | SDIO_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
|
---|
81 | To be able to use a frequency higher than 24MHz, you should use the SDIO
|
---|
82 | peripheral in bypass mode. Refer to the corresponding reference manual
|
---|
83 | for more details.
|
---|
84 |
|
---|
85 | (#) Select the corresponding SD Card according to the address read with the step 2.
|
---|
86 |
|
---|
87 | (#) Configure the SD Card in wide bus mode: 4-bits data.
|
---|
88 |
|
---|
89 | *** SD Card Read operation ***
|
---|
90 | ==============================
|
---|
91 | [..]
|
---|
92 | (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks().
|
---|
93 | This function support only 512-bytes block length (the block size should be
|
---|
94 | chosen as 512 bytes).
|
---|
95 | You can choose either one block read operation or multiple block read operation
|
---|
96 | by adjusting the "NumberOfBlocks" parameter.
|
---|
97 |
|
---|
98 | (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
|
---|
99 | This function support only 512-bytes block length (the block size should be
|
---|
100 | chosen as 512 bytes).
|
---|
101 | You can choose either one block read operation or multiple block read operation
|
---|
102 | by adjusting the "NumberOfBlocks" parameter.
|
---|
103 | After this, you have to call the function HAL_SD_CheckReadOperation(), to insure
|
---|
104 | that the read transfer is done correctly in both DMA and SD sides.
|
---|
105 |
|
---|
106 | *** SD Card Write operation ***
|
---|
107 | ===============================
|
---|
108 | [..]
|
---|
109 | (+) You can write to SD card in polling mode by using function HAL_SD_WriteBlocks().
|
---|
110 | This function support only 512-bytes block length (the block size should be
|
---|
111 | chosen as 512 bytes).
|
---|
112 | You can choose either one block read operation or multiple block read operation
|
---|
113 | by adjusting the "NumberOfBlocks" parameter.
|
---|
114 |
|
---|
115 | (+) You can write to SD card in DMA mode by using function HAL_SD_WriteBlocks_DMA().
|
---|
116 | This function support only 512-bytes block length (the block size should be
|
---|
117 | chosen as 512 byte).
|
---|
118 | You can choose either one block read operation or multiple block read operation
|
---|
119 | by adjusting the "NumberOfBlocks" parameter.
|
---|
120 | After this, you have to call the function HAL_SD_CheckWriteOperation(), to insure
|
---|
121 | that the write transfer is done correctly in both DMA and SD sides.
|
---|
122 |
|
---|
123 | *** SD card status ***
|
---|
124 | ======================
|
---|
125 | [..]
|
---|
126 | (+) At any time, you can check the SD Card status and get the SD card state
|
---|
127 | by using the HAL_SD_GetStatus() function. This function checks first if the
|
---|
128 | SD card is still connected and then get the internal SD Card transfer state.
|
---|
129 | (+) You can also get the SD card SD Status register by using the HAL_SD_SendSDStatus()
|
---|
130 | function.
|
---|
131 |
|
---|
132 | *** SD HAL driver macros list ***
|
---|
