elmot 1:d0dfbce63a89 16 ==============================================================================
elmot 1:d0dfbce63a89 17 ##### How to use this driver #####
elmot 1:d0dfbce63a89 18 ==============================================================================
elmot 1:d0dfbce63a89 19 [..]
elmot 1:d0dfbce63a89 20 This driver implements a high level communication layer for read and write from/to
elmot 1:d0dfbce63a89 21 this memory. The needed STM32 hardware resources (SDMMC1 and GPIO) are performed by
elmot 1:d0dfbce63a89 22 the user in HAL_SD_MspInit() function (MSP layer).
elmot 1:d0dfbce63a89 23 Basically, the MSP layer configuration should be the same as we provide in the
elmot 1:d0dfbce63a89 24 examples.
elmot 1:d0dfbce63a89 25 You can easily tailor this configuration according to hardware resources.
elmot 1:d0dfbce63a89 26
elmot 1:d0dfbce63a89 27 [..]
elmot 1:d0dfbce63a89 28 This driver is a generic layered driver for SDMMC memories which uses the HAL
elmot 1:d0dfbce63a89 29 SDMMC driver functions to interface with SD and uSD cards devices.
elmot 1:d0dfbce63a89 30 It is used as follows:
elmot 1:d0dfbce63a89 31
elmot 1:d0dfbce63a89 32 (#)Initialize the SDMMC1 low level resources by implementing the HAL_SD_MspInit() API:
elmot 1:d0dfbce63a89 33 (##) Call the function HAL_RCCEx_PeriphCLKConfig with RCC_PERIPHCLK_SDMMC1 for
elmot 1:d0dfbce63a89 34 PeriphClockSelection and select SDMMC1 clock source (MSI, main PLL or PLLSAI1)
elmot 1:d0dfbce63a89 35 (##) Enable the SDMMC1 interface clock using __HAL_RCC_SDMMC1_CLK_ENABLE();
elmot 1:d0dfbce63a89 36 (##) SDMMC pins configuration for SD card
elmot 1:d0dfbce63a89 37 (+++) Enable the clock for the SDMMC GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
elmot 1:d0dfbce63a89 38 (+++) Configure these SDMMC pins as alternate function pull-up using HAL_GPIO_Init()
elmot 1:d0dfbce63a89 39 and according to your pin assignment;
elmot 1:d0dfbce63a89 40 (##) DMA Configuration if you need to use DMA process (HAL_SD_ReadBlocks_DMA()
elmot 1:d0dfbce63a89 41 and HAL_SD_WriteBlocks_DMA() APIs).
elmot 1:d0dfbce63a89 42 (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE();
elmot 1:d0dfbce63a89 43 (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled.
elmot 1:d0dfbce63a89 44 (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
elmot 1:d0dfbce63a89 45 (+++) Configure the SDMMC and DMA interrupt priorities using functions
elmot 1:d0dfbce63a89 46 HAL_NVIC_SetPriority(); DMA priority is superior to SDMMC's priority
elmot 1:d0dfbce63a89 47 (+++) Enable the NVIC DMA and SDMMC IRQs using function HAL_NVIC_EnableIRQ()
elmot 1:d0dfbce63a89 48 (+++) SDMMC interrupts are managed using the macros __HAL_SD_SDMMC_ENABLE_IT()
elmot 1:d0dfbce63a89 49 and __HAL_SD_SDMMC_DISABLE_IT() inside the communication process.
elmot 1:d0dfbce63a89 50 (+++) SDMMC interrupts pending bits are managed using the macros __HAL_SD_SDMMC_GET_IT()
elmot 1:d0dfbce63a89 51 and __HAL_SD_SDMMC_CLEAR_IT()
elmot 1:d0dfbce63a89 52 (#) At this stage, you can perform SD read/write/erase operations after SD card initialization
elmot 1:d0dfbce63a89 53
elmot 1:d0dfbce63a89 54
elmot 1:d0dfbce63a89 55 *** SD Card Initialization and configuration ***
elmot 1:d0dfbce63a89 56 ================================================
elmot 1:d0dfbce63a89 57 [..]
elmot 1:d0dfbce63a89 58 To initialize the SD Card, use the HAL_SD_Init() function. It Initializes
elmot 1:d0dfbce63a89 59 the SD Card and put it into StandBy State (Ready for data transfer).
elmot 1:d0dfbce63a89 60 This function provide the following operations:
elmot 1:d0dfbce63a89 61
elmot 1:d0dfbce63a89 62 (#) Apply the SD Card initialization process at 400KHz and check the SD Card
elmot 1:d0dfbce63a89 63 type (Standard Capacity or High Capacity). You can change or adapt this
elmot 1:d0dfbce63a89 64 frequency by adjusting the "ClockDiv" field.
elmot 1:d0dfbce63a89 65 The SD Card frequency (SDMMC_CK) is computed as follows:
elmot 1:d0dfbce63a89 66 (++)
elmot 1:d0dfbce63a89 67
elmot 1:d0dfbce63a89 68 SDMMC_CK = SDMMCCLK / (ClockDiv + 2)
elmot 1:d0dfbce63a89 69
elmot 1:d0dfbce63a89 70 -@@- In initialization mode and according to the SD Card standard,
elmot 1:d0dfbce63a89 71 make sure that the SDMMC_CK frequency doesn't exceed 400KHz.
elmot 1:d0dfbce63a89 72
elmot 1:d0dfbce63a89 73 (#) Get the SD CID and CSD data. All these information are managed by the SDCardInfo
elmot 1:d0dfbce63a89 74 structure. This structure provide also ready computed SD Card capacity
elmot 1:d0dfbce63a89 75 and Block size.
elmot 1:d0dfbce63a89 76
elmot 1:d0dfbce63a89 77 -@- These information are stored in SD handle structure in case of future use.
elmot 1:d0dfbce63a89 78
elmot 1:d0dfbce63a89 79 (#) Configure the SD Card Data transfer frequency. By Default, the card transfer
elmot 1:d0dfbce63a89 80 frequency is set to 24MHz. You can change or adapt this frequency by adjusting
elmot 1:d0dfbce63a89 81 the "ClockDiv" field.
elmot 1:d0dfbce63a89 82 In transfer mode and according to the SD Card standard, make sure that the
elmot 1:d0dfbce63a89 83 SDMMC_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
elmot 1:d0dfbce63a89 84 To be able to use a frequency higher than 24MHz, you should use the SDMMC
elmot 1:d0dfbce63a89 85 peripheral in bypass mode. Refer to the corresponding reference manual
elmot 1:d0dfbce63a89 86 for more details.
elmot 1:d0dfbce63a89 87
elmot 1:d0dfbce63a89 88 (#) Select the corresponding SD Card according to the address read with the step 2.
elmot 1:d0dfbce63a89 89
elmot 1:d0dfbce63a89 90 (#) Configure the SD Card in wide bus mode: 4-bits data.
elmot 1:d0dfbce63a89 91
elmot 1:d0dfbce63a89 92 *** SD Card Read operation ***
elmot 1:d0dfbce63a89 93 ==============================
elmot 1:d0dfbce63a89 94 [..]
elmot 1:d0dfbce63a89 95 (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks().
elmot 1:d0dfbce63a89 96 This function support only 512-bytes block length (the block size should be
elmot 1:d0dfbce63a89 97 chosen as 512 bytes).
elmot 1:d0dfbce63a89 98 You can choose either one block read operation or multiple block read operation
elmot 1:d0dfbce63a89 99 by adjusting the "NumberOfBlocks" parameter.
elmot 1:d0dfbce63a89 100
elmot 1:d0dfbce63a89 101 (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
elmot 1:d0dfbce63a89 102 This function support only 512-bytes block length (the block size should be
elmot 1:d0dfbce63a89 103 chosen as 512 bytes).
elmot 1:d0dfbce63a89 104 You can choose either one block read operation or multiple block read operation
elmot 1:d0dfbce63a89 105 by adjusting the "NumberOfBlocks" parameter.
elmot 1:d0dfbce63a89 106 After this, you have to call the function HAL_SD_CheckReadOperation(), to insure
elmot 1:d0dfbce63a89 107 that the read transfer is done correctly in both DMA and SD sides.
elmot 1:d0dfbce63a89 108
elmot 1:d0dfbce63a89 109 *** SD Card Write operation ***
elmot 1:d0dfbce63a89 110 ===============================
elmot 1:d0dfbce63a89 111 [..]
elmot 1:d0dfbce63a89 112 (+) You can write to SD card in polling mode by using function HAL_SD_WriteBlocks().
elmot 1:d0dfbce63a89 113 This function support only 512-bytes block length (the block size should be
elmot 1:d0dfbce63a89 114 chosen as 512 bytes).
elmot 1:d0dfbce63a89 115 You can choose either one block read operation or multiple block read operation
elmot 1:d0dfbce63a89 116 by adjusting the "NumberOfBlocks" parameter.
elmot 1:d0dfbce63a89 117
elmot 1:d0dfbce63a89 118 (+) You can write to SD card in DMA mode by using function HAL_SD_WriteBlocks_DMA().
elmot 1:d0dfbce63a89 119 This function support only 512-bytes block length (the block size should be
elmot 1:d0dfbce63a89 120 chosen as 512 byte).
elmot 1:d0dfbce63a89 121 You can choose either one block read operation or multiple block read operation
elmot 1:d0dfbce63a89 122 by adjusting the "NumberOfBlocks" parameter.
elmot 1:d0dfbce63a89 123 After this, you have to call the function HAL_SD_CheckWriteOperation(), to insure
elmot 1:d0dfbce63a89 124 that the write transfer is done correctly in both DMA and SD sides.
elmot 1:d0dfbce63a89 125
elmot 1:d0dfbce63a89 126 *** SD card status ***
elmot 1:d0dfbce63a89 127 ======================
elmot 1:d0dfbce63a89 128 [..]
elmot 1:d0dfbce63a89 129 (+) At any time, you can check the SD Card status and get the SD card state
elmot 1:d0dfbce63a89 130 by using the HAL_SD_GetStatus() function. This function checks first if the
elmot 1:d0dfbce63a89 131 SD card is still connected and then get the internal SD Card transfer state.
elmot 1:d0dfbce63a89 132 (+) You can also get the SD card SD Status register by using the HAL_SD_SendSDStatus()
elmot 1:d0dfbce63a89 133 function.
elmot 1:d0dfbce63a89 134
elmot 1:d0dfbce63a89 135 *** SD HAL driver macros list ***
