The needed STM32 hardware resources (SDIO and - * GPIO) are defined in stm32xx_eval.h file, and the initialization is - * performed in SD_LowLevel_Init() function declared in stm32xx_eval.c - * file. - * You can easily tailor this driver to any other development board, - * by just adapting the defines for hardware resources and - * SD_LowLevel_Init() function. - * - * A - SD Card Initialization and configuration - * ============================================ - * - To initialize the SD Card, use the SD_Init() function. It - * Initializes the SD Card and put it into StandBy State (Ready - * for data transfer). This function provide the following operations: - * - * 1 - 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 - * "SDIO_INIT_CLK_DIV" define inside the stm32xx_eval.h file. - * The SD Card frequency (SDIO_CK) is computed as follows: - * - * +---------------------------------------------+ - * | SDIO_CK = SDIOCLK / (SDIO_INIT_CLK_DIV + 2) | - * +---------------------------------------------+ - * - * In initialization mode and according to the SD Card standard, - * make sure that the SDIO_CK frequency don't exceed 400KHz. - * - * 2 - 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. - * - * 3 - 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 "SDIO_TRANSFER_CLK_DIV" - * define inside the stm32xx_eval.h file. - * The SD Card frequency (SDIO_CK) is computed as follows: - * - * +---------------------------------------------+ - * | SDIO_CK = SDIOCLK / (SDIO_INIT_CLK_DIV + 2) | - * +---------------------------------------------+ - * - * In transfer mode and according to the SD Card standard, - * make sure that the SDIO_CK frequency don'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. - * - * 4 - Select the corresponding SD Card according to the address - * read with the step 2. - * - * 5 - Configure the SD Card in wide bus mode: 4-bits data. - * - * B - SD Card Read operation - * ========================== - * - You can read SD card by using two function: SD_ReadBlock() and - * SD_ReadMultiBlocks() functions. These functions support only - * 512-byte block length. - * - The SD_ReadBlock() function read only one block (512-byte). This - * function can transfer the data using DMA controller or using - * polling mode. To select between DMA or polling mode refer to - * "SD_DMA_MODE" or "SD_POLLING_MODE" inside the stm32_eval_sdio_sd.h - * file and uncomment the corresponding line. By default the SD DMA - * mode is selected - * - The SD_ReadMultiBlocks() function read only mutli blocks (multiple - * of 512-byte). - * - Any read operation should be followed by two functions to check - * if the DMA Controller and SD Card status. - * - SD_ReadWaitOperation(): this function insure that the DMA - * controller has finished all data transfer. - * - SD_GetStatus(): to check that the SD Card has finished the - * data transfer and it is ready for data. - * - * - The DMA transfer is finished by the SDIO Data End interrupt. User - * has to call the SD_ProcessIRQ() function inside the SDIO_IRQHandler(). - * Don't forget to enable the SDIO_IRQn interrupt using the NVIC controller. - * - * C - SD Card Write operation - * =========================== - * - You can write SD card by using two function: SD_WriteBlock() and - * SD_WriteMultiBlocks() functions. These functions support only - * 512-byte block length. - * - The SD_WriteBlock() function write only one block (512-byte). This - * function can transfer the data using DMA controller or using - * polling mode. To select between DMA or polling mode refer to - * "SD_DMA_MODE" or "SD_POLLING_MODE" inside the stm32_eval_sdio_sd.h - * file and uncomment the corresponding line. By default the SD DMA - * mode is selected - * - The SD_WriteMultiBlocks() function write only mutli blocks (multiple - * of 512-byte). - * - Any write operation should be followed by two functions to check - * if the DMA Controller and SD Card status. - * - SD_ReadWaitOperation(): this function insure that the DMA - * controller has finished all data transfer. - * - SD_GetStatus(): to check that the SD Card has finished the - * data transfer and it is ready for data. - * - * - The DMA transfer is finished by the SDIO Data End interrupt. User - * has to call the SD_ProcessIRQ() function inside the SDIO_IRQHandler(). - * Don't forget to enable the SDIO_IRQn interrupt using the NVIC controller. - - * - * D - SD card status - * ================== - * - At any time, you can check the SD Card status and get the SD card - * state by using the 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 - * SD_SendSDStatus() function. - * - * E - Programming Model - * ===================== - * Status = SD_Init(); // Initialization Step as described in section A - * - * // SDIO Interrupt ENABLE - * NVIC_InitStructure.NVIC_IRQChannel = SDIO_IRQn; - * NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0; - * NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0; - * NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; - * NVIC_Init(&NVIC_InitStructure); - * - * // Write operation as described in Section C - * Status = SD_WriteBlock(buffer, address, 512); - * Status = SD_WaitWriteOperation(); - * while(SD_GetStatus() != SD_TRANSFER_OK); - * - * Status = SD_WriteMultiBlocks(buffer, address, 512, NUMBEROFBLOCKS); - * Status = SD_WaitWriteOperation(); - * while(SD_GetStatus() != SD_TRANSFER_OK); - * - * // Read operation as described in Section B - * Status = SD_ReadBlock(buffer, address, 512); - * Status = SD_WaitReadOperation(); - * while(SD_GetStatus() != SD_TRANSFER_OK); - * - * Status = SD_ReadMultiBlocks(buffer, address, 512, NUMBEROFBLOCKS); - * Status = SD_WaitReadOperation(); - * while(SD_GetStatus() != SD_TRANSFER_OK); - * - * - * STM32 SDIO Pin assignment - * ========================= - * +-----------------------------------------------------------+ - * | Pin assignment | - * +-----------------------------+---------------+-------------+ - * | STM32 SDIO Pins | SD | Pin | - * +-----------------------------+---------------+-------------+ - * | SDIO D2 | D2 | 1 | - * | SDIO D3 | D3 | 2 | - * | SDIO CMD | CMD | 3 | - * | | VCC | 4 (3.3 V)| - * | SDIO CLK | CLK | 5 | - * | | GND | 6 (0 V) | - * | SDIO D0 | D0 | 7 | - * | SDIO D1 | D1 | 8 | - * +-----------------------------+---------------+-------------+ - * - * @endverbatim - * - ****************************************************************************** - * @attention - * - * THE PRESENT FIRMWARE WHICH IS FOR GUIDANCE ONLY AIMS AT PROVIDING CUSTOMERS - * WITH CODING INFORMATION REGARDING THEIR PRODUCTS IN ORDER FOR THEM TO SAVE - * TIME.
