使用C的不同数据类型的延时函数控制LED流水灯闪烁，用不同数据类型控制灯闪烁时间，定义无符号整形变量，双字节数据，值域为0~65535，程序分别用整形数据、字符型数据延时时间，主程序用循环延时打开熄灭流水灯。-C of different data types delay function control LED lights flashing, blinking time with different data types defined unsigned integer variable, double-byte data, range 0 to 65535, the program is shaping data, charactertype data delay time, the main program loop delay open off the light water.
