mbed_official | 87:085cde657901 | 18 | ##### SDMMC peripheral features ##### |
mbed_official | 87:085cde657901 | 19 | ============================================================================== |
mbed_official | 87:085cde657901 | 20 | [..] The SD/SDIO MMC card host interface (SDIO) provides an interface between the APB2 |
mbed_official | 87:085cde657901 | 21 | peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDIO cards and CE-ATA |
mbed_official | 87:085cde657901 | 22 | devices. |
mbed_official | 87:085cde657901 | 23 | |
mbed_official | 87:085cde657901 | 24 | [..] The MultiMedia Card system specifications are available through the MultiMedia Card |
mbed_official | 87:085cde657901 | 25 | Association website at www.mmca.org, published by the MMCA technical committee. |
mbed_official | 87:085cde657901 | 26 | SD memory card and SD I/O card system specifications are available through the SD card |

mbed_official | 87:085cde657901 | 41 | (+) Data and command output enable signals to control external bidirectional drivers. |
mbed_official | 87:085cde657901 | 42 | |
mbed_official | 87:085cde657901 | 43 | |
mbed_official | 87:085cde657901 | 44 | ##### How to use this driver ##### |
mbed_official | 87:085cde657901 | 45 | ============================================================================== |
mbed_official | 87:085cde657901 | 46 | [..] |
mbed_official | 87:085cde657901 | 47 | This driver is a considered as a driver of service for external devices drivers |
mbed_official | 87:085cde657901 | 48 | that interfaces with the SDIO peripheral. |
mbed_official | 87:085cde657901 | 49 | According to the device used (SD card/ MMC card / SDIO card ...), a set of APIs |
mbed_official | 87:085cde657901 | 50 | is used in the device's driver to perform SDIO operations and functionalities. |
mbed_official | 87:085cde657901 | 51 | |
mbed_official | 87:085cde657901 | 52 | This driver is almost transparent for the final user, it is only used to implement other |
mbed_official | 87:085cde657901 | 53 | functionalities of the external device. |
mbed_official | 87:085cde657901 | 54 | |
mbed_official | 87:085cde657901 | 55 | [..] |
mbed_official | 87:085cde657901 | 56 | (+) The SDIO clock (SDIOCLK = 48 MHz) is coming from a specific output of PLL |
mbed_official | 87:085cde657901 | 57 | (PLL48CLK). Before start working with SDIO peripheral make sure that the |
mbed_official | 87:085cde657901 | 58 | PLL is well configured. |
mbed_official | 87:085cde657901 | 59 | The SDIO peripheral uses two clock signals: |
mbed_official | 87:085cde657901 | 60 | (++) SDIO adapter clock (SDIOCLK = 48 MHz) |
mbed_official | 87:085cde657901 | 61 | (++) APB2 bus clock (PCLK2) |
mbed_official | 87:085cde657901 | 62 | |
mbed_official | 87:085cde657901 | 63 | -@@- PCLK2 and SDIO_CK clock frequencies must respect the following condition: |
mbed_official | 87:085cde657901 | 64 | Frequency(PCLK2) >= (3 / 8 x Frequency(SDIO_CK)) |
mbed_official | 87:085cde657901 | 65 | |
mbed_official | 87:085cde657901 | 66 | (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDIO |
mbed_official | 87:085cde657901 | 67 | peripheral. |
mbed_official | 87:085cde657901 | 68 | |
mbed_official | 87:085cde657901 | 69 | (+) Enable the Power ON State using the HAL_SDIO_PowerState_ON(hsdio) |
mbed_official | 87:085cde657901 | 70 | function and disable it using the function HAL_SDIO_PowerState_OFF(hsdio). |
mbed_official | 87:085cde657901 | 71 | |
mbed_official | 87:085cde657901 | 72 | (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros. |
mbed_official | 87:085cde657901 | 73 | |
mbed_official | 87:085cde657901 | 74 | (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT(hsdio, IT) |
mbed_official | 87:085cde657901 | 75 | and __SDIO_DISABLE_IT(hsdio, IT) if you need to use interrupt mode. |
mbed_official | 87:085cde657901 | 76 | |
mbed_official | 87:085cde657901 | 77 | (+) When using the DMA mode |
mbed_official | 87:085cde657901 | 78 | (++) Configure the DMA in the MSP layer of the external device |
mbed_official | 87:085cde657901 | 79 | (++) Active the needed channel Request |
mbed_official | 87:085cde657901 | 80 | (++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro |
mbed_official | 87:085cde657901 | 81 | __SDIO_DMA_DISABLE(). |
mbed_official | 87:085cde657901 | 82 | |
mbed_official | 87:085cde657901 | 83 | (+) To control the CPSM (Command Path State Machine) and send |
mbed_official | 87:085cde657901 | 84 | commands to the card use the HAL_SDIO_SendCommand(), |
mbed_official | 87:085cde657901 | 85 | HAL_SDIO_GetCommandResponse() and HAL_SDIO_GetResponse() functions. First, user has |
mbed_official | 87:085cde657901 | 86 | to fill the command structure (pointer to SDIO_CmdInitTypeDef) according |
mbed_official | 87:085cde657901 | 87 | to the selected command to be sent. |
mbed_official | 87:085cde657901 | 88 | The parameters that should be filled are: |
mbed_official | 87:085cde657901 | 89 | (++) Command Argument |
mbed_official | 87:085cde657901 | 90 | (++) Command Index |
mbed_official | 87:085cde657901 | 91 | (++) Command Response type |
mbed_official | 87:085cde657901 | 92 | (++) Command Wait |
mbed_official | 87:085cde657901 | 93 | (++) CPSM Status (Enable or Disable). |
mbed_official | 87:085cde657901 | 94 | |
mbed_official | 87:085cde657901 | 95 | -@@- To check if the command is well received, read the SDIO_CMDRESP |
mbed_official | 87:085cde657901 | 96 | register using the HAL_SDIO_GetCommandResponse(). |
mbed_official | 87:085cde657901 | 97 | The SDIO responses registers (SDIO_RESP1 to SDIO_RESP2), use the |
mbed_official | 87:085cde657901 | 98 | HAL_SDIO_GetResponse() function. |
mbed_official | 87:085cde657901 | 99 | |
mbed_official | 87:085cde657901 | 100 | (+) To control the DPSM (Data Path State Machine) and send/receive |
mbed_official | 87:085cde657901 | 101 | data to/from the card use the HAL_SDIO_DataConfig(), HAL_SDIO_GetDataCounter(), |
mbed_official | 87:085cde657901 | 102 | HAL_SDIO_ReadFIFO(), HAL_SDIO_WriteFIFO() and HAL_SDIO_GetFIFOCount() functions. |
