SD卡读写程序 1. sdconfig.h: 该文件为SD卡读写模块配置头文件，用户可根据实际硬件条件进行修改. 2. SD目录: SD卡读写模块的全部文件,一般不用修改. 3. 建议sdconfig.h文件不要放于SD目录中，因为SD目录中的文件一般无须修改, 而sdconfig.h通常会有改动.-1. Sdconfig.h: The document for the SD card reader module configuration header files, the user hardware according to actual conditions can be modified. 2. SD directory: SD card reader module of all the documents, the general need not be amended. 3. Proposed sdconfig. h files directory should not be put in SD because SD files in the directory are not normally required to be amended and the changes are usually sdconfig.h.
