- @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 __SDIO_CLK_ENABLE();
- (##) SDIO pins configuration for SD card
- (+++) Enable the clock for the SDIO GPIOs using the functions __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 __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_SDIO_ENABLE_IT()
- and __HAL_SD_SDIO_DISABLE_IT() inside the communication process.
- (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_SDIO_GET_IT()
- and __HAL_SD_SDIO_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
- the SD Card and put it into StandBy State (Ready for data transfer).
- This function provide the following operations:
-
- (#) Apply the SD Card initialization process at 400KHz and check the SD Card
- type (Standard Capacity or High Capacity). 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.
-
- (#) Get the SD CID and CSD data. All these information are managed by the SDCardInfo
- structure. This structure provide also ready computed SD Card capacity
- and Block size.
-
- -@- These information are stored in SD handle structure in case of future use.
-
- (#) Configure the SD Card Data transfer frequency. By Default, the card transfer
- frequency is set to 48MHz / (SDIO_TRANSFER_CLK_DIV + 2) = 8MHz. 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 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 support only 512-byte block length (the block size should be
- chosen as 512 byte).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
-
- (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
- This function support only 512-byte block length (the block size should be
- chosen as 512 byte).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to call the function HAL_SD_CheckReadOperation(), to insure
- that the read transfer is done correctly in both DMA and SD sides.
-
- *** SD Card Write operation ***
- ===============================
- [..]
- (+) You can write to SD card in polling mode by using function HAL_SD_WriteBlocks().
- This function support only 512-byte block length (the block size should be
- chosen as 512 byte).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
-
- (+) You can write to SD card in DMA mode by using function HAL_SD_WriteBlocks_DMA().
- This function support only 512-byte block length (the block size should be
- chosen as 512 byte).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to call the function HAL_SD_CheckWriteOperation(), to insure
- that the write transfer is done correctly in both DMA and SD sides.
-
- *** SD card status ***
- ======================
- [..]
- (+) At any time, you can check the SD Card status and get the SD card state
- by using the HAL_SD_GetStatus() function. This function checks first if the
- SD card is still connected and then get the internal SD Card transfer state.
- (+) You can also get the SD card SD Status register by using the HAL_SD_SendSDStatus()
- function.
-
- *** SD HAL driver macros list ***
- ==================================
- [..]
- Below the list of most used macros in SD HAL driver.
-
- (+) __HAL_SD_SDIO_ENABLE : Enable the SD device
- (+) __HAL_SD_SDIO_DISABLE : Disable the SD device
- (+) __HAL_SD_SDIO_DMA_ENABLE: Enable the SDIO DMA transfer
- (+) __HAL_SD_SDIO_DMA_DISABLE: Disable the SDIO DMA transfer
- (+) __HAL_SD_SDIO_ENABLE_IT: Enable the SD device interrupt
- (+) __HAL_SD_SDIO_DISABLE_IT: Disable the SD device interrupt
- (+) __HAL_SD_SDIO_GET_FLAG:Check whether the specified SD flag is set or not
- (+) __HAL_SD_SDIO_CLEAR_FLAG: Clear the SD's pending flags
-
- (@) You can refer to the SD HAL driver header file for more useful macros
