27 | ##### SDMMC peripheral features ##### |
||
28 | ============================================================================== |
||
29 | [..] The SD/SDMMC MMC card host interface (SDMMC) provides an interface between the AHB |
||
30 | peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDMMC cards and CE-ATA |
||
31 | devices. |
||
32 | |||
33 | [..] The SDMMC features include the following: |
||
34 | (+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support |
||
35 | for three different databus modes: 1-bit (default), 4-bit and 8-bit |
||
36 | (+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility) |
||
37 | (+) Full compliance with SD Memory Card Specifications Version 2.0 |
||
38 | (+) Full compliance with SD I/O Card Specification Version 2.0: card support for two |
||
39 | different data bus modes: 1-bit (default) and 4-bit |
||
40 | (+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol |
||
41 | Rev1.1) |
||
42 | (+) Data transfer up to 48 MHz for the 8 bit mode |
||
43 | (+) Data and command output enable signals to control external bidirectional drivers |
||
44 | |||
45 | ##### How to use this driver ##### |
||
46 | ============================================================================== |
||
47 | [..] |
||
48 | This driver is a considered as a driver of service for external devices drivers |
||
49 | that interfaces with the SDMMC peripheral. |
||
50 | According to the device used (SD card/ MMC card / SDMMC card ...), a set of APIs |
||
51 | is used in the device's driver to perform SDMMC operations and functionalities. |
||
52 | |||
53 | This driver is almost transparent for the final user, it is only used to implement other |
||
54 | functionalities of the external device. |
||
55 | |||
56 | [..] |
||
57 | (+) The SDMMC clock (SDMMCCLK = 48 MHz) is coming from a specific output (MSI, PLLUSB1CLK, |
||
58 | PLLUSB2CLK). Before start working with SDMMC peripheral make sure that the |
||
59 | PLL is well configured. |
||
60 | The SDMMC peripheral uses two clock signals: |
||
61 | (++) SDMMC adapter clock (SDMMCCLK = 48 MHz) |
||
62 | (++) APB2 bus clock (PCLK2) |
||
63 | |||
64 | -@@- PCLK2 and SDMMC_CK clock frequencies must respect the following condition: |
||
65 | Frequency(PCLK2) >= (3 / 8 x Frequency(SDMMC_CK)) |
||
66 | |||
67 | (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC |
||
68 | peripheral. |
||
69 | |||
70 | (+) Enable the Power ON State using the SDIO_PowerState_ON() |
||
71 | function and disable it using the function SDIO_PowerState_OFF(). |
||
72 | |||
73 | (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros. |
||
74 | |||
75 | (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT() |
||
76 | and __SDIO_DISABLE_IT() if you need to use interrupt mode. |
||
77 | |||
78 | (+) When using the DMA mode |
||
79 | (++) Configure the DMA in the MSP layer of the external device |
||
80 | (++) Active the needed channel Request |
||
81 | (++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro |
||
82 | __SDIO_DMA_DISABLE(). |
||
83 | |||
84 | (+) To control the CPSM (Command Path State Machine) and send |
||
85 | commands to the card use the SDIO_SendCommand(), |
||
86 | SDIO_GetCommandResponse() and SDIO_GetResponse() functions. First, user has |
||
87 | to fill the command structure (pointer to SDIO_CmdInitTypeDef) according |
||
88 | to the selected command to be sent. |
||
89 | The parameters that should be filled are: |
||
90 | (++) Command Argument |
||
91 | (++) Command Index |
||
92 | (++) Command Response type |
||
93 | (++) Command Wait |
||
94 | (++) CPSM Status (Enable or Disable). |
||
95 | |||
96 | -@@- To check if the command is well received, read the SDIO_CMDRESP |
||
97 | register using the SDIO_GetCommandResponse(). |
||
98 | The SDMMC responses registers (SDIO_RESP1 to SDIO_RESP2), use the |
||
99 | SDIO_GetResponse() function. |
||
100 | |||
101 | (+) To control the DPSM (Data Path State Machine) and send/receive |
||
102 | data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(), |
||
103 | SDIO_ReadFIFO(), SDIO_WriteFIFO() and SDIO_GetFIFOCount() functions. |
||
104 | |||
105 | *** Read Operations *** |
||
106 | ======================= |
||
107 | [..] |
||
108 | (#) First, user has to fill the data structure (pointer to |
||
109 | SDIO_DataInitTypeDef) according to the selected data type to be received. |
||
110 | The parameters that should be filled are: |
||
111 | (++) Data TimeOut |
||
112 | (++) Data Length |
||
113 | (++) Data Block size |
||
114 | (++) Data Transfer direction: should be from card (To SDMMC) |
||
115 | (++) Data Transfer mode |
||
116 | (++) DPSM Status (Enable or Disable) |
||
117 | |||
118 | (#) Configure the SDMMC resources to receive the data from the card |
||
119 | according to selected transfer mode (Refer to Step 8, 9 and 10). |
||
120 | |||
121 | (#) Send the selected Read command (refer to step 11). |
||
122 | |||
123 | (#) Use the SDIO flags/interrupts to check the transfer status. |
||
124 | |||
125 | *** Write Operations *** |
||
126 | ======================== |
||
127 | [..] |
||
128 | (#) First, user has to fill the data structure (pointer to |
||
129 | SDIO_DataInitTypeDef) according to the selected data type to be received. |
||
130 | The parameters that should be filled are: |
||
131 | (++) Data TimeOut |
||
132 | (++) Data Length |
||
133 | (++) Data Block size |
||
134 | (++) Data Transfer direction: should be to card (To CARD) |
||
135 | (++) Data Transfer mode |
||
136 | (++) DPSM Status (Enable or Disable) |
||
137 | |||
138 | (#) Configure the SDMMC resources to send the data to the card according to |
||
139 | selected transfer mode. |
||
140 | |||
141 | (#) Send the selected Write command. |
||
142 | |||
143 | (#) Use the SDIO flags/interrupts to check the transfer status. |
||
144 | |||
145 | *** Command management operations *** |
||
146 | ===================================== |
||
147 | [..] |
||
148 | (#) The commands used for Read/Write/Erase operations are managed in |
||
149 | separate functions. |
||
150 | Each function allows to send the needed command with the related argument, |
||
151 | then check the response. |
||
152 | By the same approach, you could implement a command and check the response. |
