This is a generic FIFO buffer that can be used to store any kind of items. It is written in C language and can be compiled and used on almost any architecture. It was designed to be used on memory limited architectures such as microcontrollers. Examples of the applications that can be built with this library include:

利用单片机作为芯片，利用点阵按钮通过继电器控制LED灯(Using single chip microcomputer as a chip, using bitmap button by relay control LED lights)

说明：  24C08多花样流水，采用51开发板，编程使LED呈流水灯，初学者的好例子。(24C08 multi-pattern, running water, with 51 development board, program the LED lights were water, a good example for beginners.)
