- ******************************************************************************
- * @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.
