phungductung | 0:8ede47d38d10 | 18 | ##### SDMMC peripheral features ##### |
phungductung | 0:8ede47d38d10 | 19 | ============================================================================== |
phungductung | 0:8ede47d38d10 | 20 | [..] The SD/SDMMC MMC card host interface (SDMMC) provides an interface between the APB2 |
phungductung | 0:8ede47d38d10 | 21 | peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDMMC cards and CE-ATA |
phungductung | 0:8ede47d38d10 | 22 | devices. |
phungductung | 0:8ede47d38d10 | 23 | |
phungductung | 0:8ede47d38d10 | 24 | [..] The SDMMC features include the following: |
phungductung | 0:8ede47d38d10 | 25 | (+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support |
phungductung | 0:8ede47d38d10 | 26 | for three different databus modes: 1-bit (default), 4-bit and 8-bit |
phungductung | 0:8ede47d38d10 | 27 | (+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility) |
phungductung | 0:8ede47d38d10 | 28 | (+) Full compliance with SD Memory Card Specifications Version 2.0 |
phungductung | 0:8ede47d38d10 | 29 | (+) Full compliance with SD I/O Card Specification Version 2.0: card support for two |
phungductung | 0:8ede47d38d10 | 30 | different data bus modes: 1-bit (default) and 4-bit |
phungductung | 0:8ede47d38d10 | 31 | (+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol |
phungductung | 0:8ede47d38d10 | 32 | Rev1.1) |
phungductung | 0:8ede47d38d10 | 33 | (+) Data transfer up to 48 MHz for the 8 bit mode |
phungductung | 0:8ede47d38d10 | 34 | (+) Data and command output enable signals to control external bidirectional drivers. |
phungductung | 0:8ede47d38d10 | 35 | |
phungductung | 0:8ede47d38d10 | 36 | |
phungductung | 0:8ede47d38d10 | 37 | ##### How to use this driver ##### |
phungductung | 0:8ede47d38d10 | 38 | ============================================================================== |
phungductung | 0:8ede47d38d10 | 39 | [..] |
phungductung | 0:8ede47d38d10 | 40 | This driver is a considered as a driver of service for external devices drivers |
phungductung | 0:8ede47d38d10 | 41 | that interfaces with the SDMMC peripheral. |
phungductung | 0:8ede47d38d10 | 42 | According to the device used (SD card/ MMC card / SDMMC card ...), a set of APIs |
phungductung | 0:8ede47d38d10 | 43 | is used in the device's driver to perform SDMMC operations and functionalities. |
phungductung | 0:8ede47d38d10 | 44 | |
phungductung | 0:8ede47d38d10 | 45 | This driver is almost transparent for the final user, it is only used to implement other |
phungductung | 0:8ede47d38d10 | 46 | functionalities of the external device. |
phungductung | 0:8ede47d38d10 | 47 | |
phungductung | 0:8ede47d38d10 | 48 | [..] |
phungductung | 0:8ede47d38d10 | 49 | (+) The SDMMC clock (SDMMCCLK = 48 MHz) is coming from a specific output of PLL |
phungductung | 0:8ede47d38d10 | 50 | (PLL48CLK). Before start working with SDMMC peripheral make sure that the |
phungductung | 0:8ede47d38d10 | 51 | PLL is well configured. |
phungductung | 0:8ede47d38d10 | 52 | The SDMMC peripheral uses two clock signals: |
phungductung | 0:8ede47d38d10 | 53 | (++) SDMMC adapter clock (SDMMCCLK = 48 MHz) |
phungductung | 0:8ede47d38d10 | 54 | (++) APB2 bus clock (PCLK2) |
phungductung | 0:8ede47d38d10 | 55 | |
phungductung | 0:8ede47d38d10 | 56 | -@@- PCLK2 and SDMMC_CK clock frequencies must respect the following condition: |
phungductung | 0:8ede47d38d10 | 57 | Frequency(PCLK2) >= (3 / 8 x Frequency(SDMMC_CK)) |
phungductung | 0:8ede47d38d10 | 58 | |
phungductung | 0:8ede47d38d10 | 59 | (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC |
phungductung | 0:8ede47d38d10 | 60 | peripheral. |
phungductung | 0:8ede47d38d10 | 61 | |
phungductung | 0:8ede47d38d10 | 62 | (+) Enable the Power ON State using the SDMMC_PowerState_ON(SDMMCx) |
phungductung | 0:8ede47d38d10 | 63 | function and disable it using the function SDMMC_PowerState_OFF(SDMMCx). |
phungductung | 0:8ede47d38d10 | 64 | |
phungductung | 0:8ede47d38d10 | 65 | (+) Enable/Disable the clock using the __SDMMC_ENABLE()/__SDMMC_DISABLE() macros. |
phungductung | 0:8ede47d38d10 | 66 | |
phungductung | 0:8ede47d38d10 | 67 | (+) Enable/Disable the peripheral interrupts using the macros __SDMMC_ENABLE_IT(hSDMMC, IT) |
phungductung | 0:8ede47d38d10 | 68 | and __SDMMC_DISABLE_IT(hSDMMC, IT) if you need to use interrupt mode. |
phungductung | 0:8ede47d38d10 | 69 | |
phungductung | 0:8ede47d38d10 | 70 | (+) When using the DMA mode |
phungductung | 0:8ede47d38d10 | 71 | (++) Configure the DMA in the MSP layer of the external device |
phungductung | 0:8ede47d38d10 | 72 | (++) Active the needed channel Request |
phungductung | 0:8ede47d38d10 | 73 | (++) Enable the DMA using __SDMMC_DMA_ENABLE() macro or Disable it using the macro |
phungductung | 0:8ede47d38d10 | 74 | __SDMMC_DMA_DISABLE(). |
phungductung | 0:8ede47d38d10 | 75 | |
phungductung | 0:8ede47d38d10 | 76 | (+) To control the CPSM (Command Path State Machine) and send |
phungductung | 0:8ede47d38d10 | 77 | commands to the card use the SDMMC_SendCommand(SDMMCx), |
phungductung | 0:8ede47d38d10 | 78 | SDMMC_GetCommandResponse() and SDMMC_GetResponse() functions. First, user has |
phungductung | 0:8ede47d38d10 | 79 | to fill the command structure (pointer to SDMMC_CmdInitTypeDef) according |
phungductung | 0:8ede47d38d10 | 80 | to the selected command to be sent. |
phungductung | 0:8ede47d38d10 | 81 | The parameters that should be filled are: |
phungductung | 0:8ede47d38d10 | 82 | (++) Command Argument |
phungductung | 0:8ede47d38d10 | 83 | (++) Command Index |
phungductung | 0:8ede47d38d10 | 84 | (++) Command Response type |
phungductung | 0:8ede47d38d10 | 85 | (++) Command Wait |
phungductung | 0:8ede47d38d10 | 86 | (++) CPSM Status (Enable or Disable). |
phungductung | 0:8ede47d38d10 | 87 | |
phungductung | 0:8ede47d38d10 | 88 | -@@- To check if the command is well received, read the SDMMC_CMDRESP |
phungductung | 0:8ede47d38d10 | 89 | register using the SDMMC_GetCommandResponse(). |
phungductung | 0:8ede47d38d10 | 90 | The SDMMC responses registers (SDMMC_RESP1 to SDMMC_RESP2), use the |
phungductung | 0:8ede47d38d10 | 91 | SDMMC_GetResponse() function. |
phungductung | 0:8ede47d38d10 | 92 | |
phungductung | 0:8ede47d38d10 | 93 | (+) To control the DPSM (Data Path State Machine) and send/receive |
phungductung | 0:8ede47d38d10 | 94 | data to/from the card use the SDMMC_DataConfig(), SDMMC_GetDataCounter(), |
phungductung | 0:8ede47d38d10 | 95 | SDMMC_ReadFIFO(), DIO_WriteFIFO() and SDMMC_GetFIFOCount() functions. |
