@verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + This driver implements a high level communication layer for read and write from/to + this memory. The needed STM32 hardware resources (SDIO and GPIO) are performed by + the user in HAL_SD_MspInit() function (MSP layer). + Basically, the MSP layer configuration should be the same as we provide in the + examples. + You can easily tailor this configuration according to hardware resources. + + [..] + This driver is a generic layered driver for SDIO memories which uses the HAL + SDIO driver functions to interface with SD and uSD cards devices. + It is used as follows: + + (#)Initialize the SDIO low level resources by implement the HAL_SD_MspInit() API: + (##) Enable the SDIO interface clock using __HAL_RCC_SDIO_CLK_ENABLE(); + (##) SDIO pins configuration for SD card + (+++) Enable the clock for the SDIO GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE(); + (+++) Configure these SDIO pins as alternate function pull-up using HAL_GPIO_Init() + and according to your pin assignment; + (##) DMA Configuration if you need to use DMA process (HAL_SD_ReadBlocks_DMA() + and HAL_SD_WriteBlocks_DMA() APIs). + (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE(); + (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled. + (##) NVIC configuration if you need to use interrupt process when using DMA transfer. + (+++) Configure the SDIO and DMA interrupt priorities using functions + HAL_NVIC_SetPriority(); DMA priority is superior to SDIO's priority + (+++) Enable the NVIC DMA and SDIO IRQs using function HAL_NVIC_EnableIRQ() + (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT() + and __HAL_SD_DISABLE_IT() inside the communication process. + (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_GET_IT() + and __HAL_SD_CLEAR_IT() + (##) NVIC configuration if you need to use interrupt process (HAL_SD_ReadBlocks_IT() + and HAL_SD_WriteBlocks_IT() APIs). + (+++) Configure the SDIO interrupt priorities using function + HAL_NVIC_SetPriority(); + (+++) Enable the NVIC SDIO IRQs using function HAL_NVIC_EnableIRQ() + (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT() + and __HAL_SD_DISABLE_IT() inside the communication process. + (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_GET_IT() + and __HAL_SD_CLEAR_IT() + (#) At this stage, you can perform SD read/write/erase operations after SD card initialization + + + *** SD Card Initialization and configuration *** + ================================================ + [..] + To initialize the SD Card, use the HAL_SD_Init() function. It Initializes + SDIO IP(STM32 side) and the SD Card, and put it into StandBy State (Ready for data transfer). + This function provide the following operations: + + (#) Initialize the SDIO peripheral interface with defaullt configuration. + The initialization process is done at 400KHz. You can change or adapt + this frequency by adjusting the "ClockDiv" field. + The SD Card frequency (SDIO_CK) is computed as follows: + + SDIO_CK = SDIOCLK / (ClockDiv + 2) + + In initialization mode and according to the SD Card standard, + make sure that the SDIO_CK frequency doesn't exceed 400KHz. + + This phase of initialization is done through SDIO_Init() and + SDIO_PowerState_ON() SDIO low level APIs. + + (#) Initialize the SD card. The API used is HAL_SD_InitCard(). + This phase allows the card initialization and identification + and check the SD Card type (Standard Capacity or High Capacity) + The initialization flow is compatible with SD standard. + + This API (HAL_SD_InitCard()) could be used also to reinitialize the card in case + of plug-off plug-in. + + (#) Configure the SD Card Data transfer frequency. By Default, the card transfer + frequency is set to 24MHz. You can change or adapt this frequency by adjusting + the "ClockDiv" field. + In transfer mode and according to the SD Card standard, make sure that the + SDIO_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch. + To be able to use a frequency higher than 24MHz, you should use the SDIO + peripheral in bypass mode. Refer to the corresponding reference manual + for more details. + + (#) Select the corresponding SD Card according to the address read with the step 2. + + (#) Configure the SD Card in wide bus mode: 4-bits data. + + *** SD Card Read operation *** + ============================== + [..] + (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks(). + This function allows the read of 512 bytes blocks. + You can choose either one block read operation or multiple block read operation + by adjusting the "NumberOfBlocks" parameter. + After this, you have to ensure that the transfer is done correctly.
