+  ******************************************************************************
+  * @file    stm32_eval_i2c_tsensor.c
+  * @author  MCD Application Team
+  * @version V4.5.0
+  * @date    07-March-2011
+  * @brief   This file provides a set of functions needed to manage the I2C LM75 
+  *          temperature sensor mounted on STM32xx-EVAL board (refer to stm32_eval.h
+  *          to know about the boards supporting this sensor). 
+  *          It implements a high level communication layer for read and write 
+  *          from/to this sensor. The needed STM32 hardware resources (I2C and 
+  *          GPIO) are defined in stm32xx_eval.h file, and the initialization is 
+  *          performed in LM75_LowLevel_Init() function declared in stm32xx_eval.c 
+  *          file.
+  *            
+  *          Note:
+  *          -----    
+  *          This driver uses the DMA method to send and receive data on I2C bus,
+  *          which allows higher efficiency and reliability  of the communication.
+  *                 
+  *          You can easily tailor this driver to any other development board, 
+  *          by just adapting the defines for hardware resources and 
+  *          LM75_LowLevel_Init() function.

+  * @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_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_ReadMultiBlocks(buffer, address, 512, NUMBEROFBLOCKS);
+  *             Status = SD_WaitReadOperation();
+  *             while(SD_GetStatus() != SD_TRANSFER_OK);            
+  *

+  *          to know about the boards supporting this memory). 
+  *          It implements a high level communication layer for read and write 
+  *          from/to this memory. The needed STM32 hardware resources (SPI and 
+  *          GPIO) are defined in stm32xx_eval.h file, and the initialization is 
+  *          performed in sFLASH_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 
+  *          sFLASH_LowLevel_Init() function.

+  * @file    stm32_eval_spi_sd.c
+  * @author  MCD Application Team
+  * @version V4.5.0
+  * @date    07-March-2011
+  * @brief   This file provides a set of functions needed to manage the SPI SD 
+  *          Card memory mounted on STM32xx-EVAL board (refer to stm32_eval.h
+  *          to know about the boards supporting this memory). 
+  *          It implements a high level communication layer for read and write 
+  *          from/to this memory. The needed STM32 hardware resources (SPI 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.
