| mbed_official | 235:685d5f11838f | 38 | ============================================================================== |
| mbed_official | 235:685d5f11838f | 39 | [..] |
| mbed_official | 235:685d5f11838f | 40 | This driver is a considered as a driver of service for external devices drivers |
| mbed_official | 235:685d5f11838f | 41 | that interfaces with the SDIO peripheral. |
| mbed_official | 235:685d5f11838f | 42 | According to the device used (SD card/ MMC card / SDIO card ...), a set of APIs |
| mbed_official | 235:685d5f11838f | 43 | is used in the device's driver to perform SDIO operations and functionalities. |
| mbed_official | 235:685d5f11838f | 44 | |
| mbed_official | 235:685d5f11838f | 45 | This driver is almost transparent for the final user, it is only used to implement other |
| mbed_official | 235:685d5f11838f | 46 | functionalities of the external device. |
| mbed_official | 235:685d5f11838f | 47 | |
| mbed_official | 235:685d5f11838f | 48 | [..] |
| mbed_official | 235:685d5f11838f | 49 | (+) The SDIO clock (SDIOCLK = 48 MHz) is coming from a specific output of PLL |
| mbed_official | 235:685d5f11838f | 50 | (PLL48CLK). Before start working with SDIO peripheral make sure that the |
| mbed_official | 235:685d5f11838f | 51 | PLL is well configured. |
| mbed_official | 235:685d5f11838f | 52 | The SDIO peripheral uses two clock signals: |
| mbed_official | 235:685d5f11838f | 53 | (++) SDIO adapter clock (SDIOCLK = 48 MHz) |
| mbed_official | 235:685d5f11838f | 54 | (++) APB2 bus clock (PCLK2) |
| mbed_official | 235:685d5f11838f | 55 | |
| mbed_official | 235:685d5f11838f | 56 | -@@- PCLK2 and SDIO_CK clock frequencies must respect the following condition: |
| mbed_official | 235:685d5f11838f | 57 | Frequency(PCLK2) >= (3 / 8 x Frequency(SDIO_CK)) |
| mbed_official | 235:685d5f11838f | 58 | |
| mbed_official | 235:685d5f11838f | 59 | (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDIO |
| mbed_official | 235:685d5f11838f | 60 | peripheral. |
| mbed_official | 235:685d5f11838f | 61 | |
| mbed_official | 235:685d5f11838f | 62 | (+) Enable the Power ON State using the SDIO_PowerState_ON(SDIOx) |
| mbed_official | 532:fe11edbda85c | 63 | function and disable it using the function SDIO_PowerState_OFF(SDIOx). |
| mbed_official | 235:685d5f11838f | 64 | |
| mbed_official | 235:685d5f11838f | 65 | (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros. |
| mbed_official | 235:685d5f11838f | 66 | |
| mbed_official | 235:685d5f11838f | 67 | (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT(hsdio, IT) |
| mbed_official | 235:685d5f11838f | 68 | and __SDIO_DISABLE_IT(hsdio, IT) if you need to use interrupt mode. |
| mbed_official | 235:685d5f11838f | 69 | |
| mbed_official | 235:685d5f11838f | 70 | (+) When using the DMA mode |
| mbed_official | 235:685d5f11838f | 71 | (++) Configure the DMA in the MSP layer of the external device |
| mbed_official | 235:685d5f11838f | 72 | (++) Active the needed channel Request |
| mbed_official | 235:685d5f11838f | 73 | (++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro |
| mbed_official | 235:685d5f11838f | 74 | __SDIO_DMA_DISABLE(). |
| mbed_official | 235:685d5f11838f | 75 | |
| mbed_official | 235:685d5f11838f | 76 | (+) To control the CPSM (Command Path State Machine) and send |
| mbed_official | 235:685d5f11838f | 77 | commands to the card use the SDIO_SendCommand(SDIOx), |
| mbed_official | 235:685d5f11838f | 78 | SDIO_GetCommandResponse() and SDIO_GetResponse() functions. First, user has |
| mbed_official | 235:685d5f11838f | 79 | to fill the command structure (pointer to SDIO_CmdInitTypeDef) according |
| mbed_official | 235:685d5f11838f | 80 | to the selected command to be sent. |
| mbed_official | 235:685d5f11838f | 81 | The parameters that should be filled are: |
| mbed_official | 235:685d5f11838f | 82 | (++) Command Argument |
| mbed_official | 235:685d5f11838f | 83 | (++) Command Index |

| mbed_official | 235:685d5f11838f | 87 | |
| mbed_official | 235:685d5f11838f | 88 | -@@- To check if the command is well received, read the SDIO_CMDRESP |
| mbed_official | 235:685d5f11838f | 89 | register using the SDIO_GetCommandResponse(). |
| mbed_official | 235:685d5f11838f | 90 | The SDIO responses registers (SDIO_RESP1 to SDIO_RESP2), use the |
| mbed_official | 235:685d5f11838f | 91 | SDIO_GetResponse() function. |
| mbed_official | 235:685d5f11838f | 92 | |
| mbed_official | 235:685d5f11838f | 93 | (+) To control the DPSM (Data Path State Machine) and send/receive |
| mbed_official | 235:685d5f11838f | 94 | data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(), |
| mbed_official | 235:685d5f11838f | 95 | SDIO_ReadFIFO(), DIO_WriteFIFO() and SDIO_GetFIFOCount() functions. |
