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.
