基于W78E58单片机的税控器设计

介绍利用单片机W78E58设计税控器的方案,介绍了硬件的设计方案,以及软件各个模块的功能划分,并重点介绍了分包通信协议的设计。实践证明,根据此设计思想可以设计出符合国标的税控器系统。

This paper introduces a project which using microcomputer W78E58 to design a machine which can control tax,and introduces the scheme of hardware,the function of each module,and especially introduce the design of communication subsection agreement.The result show that this project is success.
