采用ATMEL公司的AT89C51单片机为核心，实现对交通灯的控制。并扩展了红绿灯的倒计时功能，具有实用性。文中详细描述了程序设计原理及过程，首先进行程序的编写，通过达爱思集团的DAIS-596H高级组合仿真开发系统并连接国防科大实验板，多次调试运行得到满意结果后，用启东市英赛特计算机厂的RP-3000通用编程器将程序固化到AT89C51芯片上，由其完成控制功能。- ATMEL Corporation AT89C51 used as the core single chip to achiev

Computer Systems: A Programmer s Perspective

The present paper describes the design of a cost effective, better resolution data acquisition system (DAS) which is compatible to most of the PC and laptops. A low cost DAS has been designed using PIC12F675 having 4-channel analog input with 10-
