|
|
+ * @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).
|
|
|
+ *

|

|
|
|

|
|
|
+ * ===================================================================
|
|
|
+ * 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);
