本次设计为十字路口交通灯控制系统设计,硬件部分它以8031单片机为核心,并在此基础上扩展了程序存储器（EPROM）2764、静态数据存储器（SRAM）6264，利用地址锁存器74LS373扩展I/O并行接口芯片8255A。软件部分它结合定时/计数等知识进行程序编译。-The design for the intersection traffic light control system design, hardware components it to 8031 as the core, and on this basis, expanded program memory (EPROM) 2764, static data memory (SRAM) 6264, extended use of address latch 74LS373 I/O parallel interface chip 8255A. It combines the software part of the timer/counter and other knowledge to compile.
