- * @file stm32_eval_sdio_sd.c
- * @author MCD Application Team
- * @version V4.6.1
- * @date 18-April-2011
- * @brief This file provides a set of functions needed to manage the SDIO SD
- * Card memory mounted on STM32xx-EVAL board (refer to stm32_eval.h
- * to know about the boards supporting this memory).
- *
- *
- * @verbatim
- *
- * ===================================================================
- * How to use this driver
- * ===================================================================
- * It implements a high level communication layer for read and write
- * from/to this memory. 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)|
