采用C 语言编写程序，选择了软件分层次设计的方式，有利于实现较复杂的算法和程序结构优化。系统不仅能够实现数字、字母、汉字等信息的显示，同时还可以实现信息的定时循环和转换、滚屏等功能。-The stratified design of software is in favour of achieving morecomplex algorithms and the optimization of the program structure. The system can beachieved not only numbers, letters, Chinese characters, such as information display, butalso the cycle of the timing information ,the convert and the function of flashing Scroll,etc.
