| 38domo | 14:ed51426706bd | 5 | * @version V1.0.0 |
| 38domo | 14:ed51426706bd | 6 | * @date 25-June-2015 |
| 38domo | 14:ed51426706bd | 7 | * @brief This file includes the uSD card driver mounted on STM32746G-Discovery |
| 38domo | 14:ed51426706bd | 8 | * board. |
| 38domo | 14:ed51426706bd | 9 | @verbatim |
| 38domo | 14:ed51426706bd | 10 | 1. How To use this driver: |
| 38domo | 14:ed51426706bd | 11 | -------------------------- |
| 38domo | 14:ed51426706bd | 12 | - This driver is used to drive the micro SD external card mounted on STM32746G-Discovery |
| 38domo | 14:ed51426706bd | 13 | board. |
| 38domo | 14:ed51426706bd | 14 | - This driver does not need a specific component driver for the micro SD device |
| 38domo | 14:ed51426706bd | 15 | to be included with. |
| 38domo | 14:ed51426706bd | 16 | |
| 38domo | 14:ed51426706bd | 17 | 2. Driver description: |
| 38domo | 14:ed51426706bd | 18 | --------------------- |
| 38domo | 14:ed51426706bd | 19 | + Initialization steps: |
| 38domo | 14:ed51426706bd | 20 | o Initialize the micro SD card using the BSP_SD_Init() function. This |
| 38domo | 14:ed51426706bd | 21 | function includes the MSP layer hardware resources initialization and the |
| 38domo | 14:ed51426706bd | 22 | SDIO interface configuration to interface with the external micro SD. It |
| 38domo | 14:ed51426706bd | 23 | also includes the micro SD initialization sequence. |
| 38domo | 14:ed51426706bd | 24 | o To check the SD card presence you can use the function BSP_SD_IsDetected() which |
| 38domo | 14:ed51426706bd | 25 | returns the detection status |
| 38domo | 14:ed51426706bd | 26 | o If SD presence detection interrupt mode is desired, you must configure the |
| 38domo | 14:ed51426706bd | 27 | SD detection interrupt mode by calling the function BSP_SD_ITConfig(). The interrupt |
| 38domo | 14:ed51426706bd | 28 | is generated as an external interrupt whenever the micro SD card is |
| 38domo | 14:ed51426706bd | 29 | plugged/unplugged in/from the board. |
| 38domo | 14:ed51426706bd | 30 | o The function BSP_SD_GetCardInfo() is used to get the micro SD card information |
| 38domo | 14:ed51426706bd | 31 | which is stored in the structure "HAL_SD_CardInfoTypedef". |
| 38domo | 14:ed51426706bd | 32 | |
| 38domo | 14:ed51426706bd | 33 | + Micro SD card operations |
| 38domo | 14:ed51426706bd | 34 | o The micro SD card can be accessed with read/write block(s) operations once |
| 38domo | 14:ed51426706bd | 35 | it is ready for access. The access can be performed whether using the polling |
| 38domo | 14:ed51426706bd | 36 | mode by calling the functions BSP_SD_ReadBlocks()/BSP_SD_WriteBlocks(), or by DMA |
| 38domo | 14:ed51426706bd | 37 | transfer using the functions BSP_SD_ReadBlocks_DMA()/BSP_SD_WriteBlocks_DMA() |
| 38domo | 14:ed51426706bd | 38 | o The DMA transfer complete is used with interrupt mode. Once the SD transfer |
| 38domo | 14:ed51426706bd | 39 | is complete, the SD interrupt is handled using the function BSP_SD_IRQHandler(), |
| 38domo | 14:ed51426706bd | 40 | the DMA Tx/Rx transfer complete are handled using the functions |
| 38domo | 14:ed51426706bd | 41 | BSP_SD_DMA_Tx_IRQHandler()/BSP_SD_DMA_Rx_IRQHandler(). The corresponding user callbacks |
| 38domo | 14:ed51426706bd | 42 | are implemented by the user at application level. |
| 38domo | 14:ed51426706bd | 43 | o The SD erase block(s) is performed using the function BSP_SD_Erase() with specifying |
| 38domo | 14:ed51426706bd | 44 | the number of blocks to erase. |
| 38domo | 14:ed51426706bd | 45 | o The SD runtime status is returned when calling the function BSP_SD_GetStatus(). |
