此程序首先将CH375程序库及CH375芯片进行初始化，随后开始检测U盘是否已经插入，U盘插入后，读取U盘的物理总容量，单位为扇区，即一共有多少个扇区。然后获取U盘的格式化容量、剩余容量及文件系统类型。-This program first CH375 CH375 chip library and initialized, then start testing it has been inserted U disk, U disk inserted, to read U disk total c

用于SD卡的程序，包含各种读盘分扇区之类的功能，对于需要大量记录数据的应用，非常有用。(SD card for the program, including a variety of read disk, sub sectors, and other functions, for the need for a large number of data recording applications, very useful.)
