基于STC单片机的交通信号指示灯的设计

Design of Traffic Signal Indicator Based on STC MCU

介绍了交通信号灯的硬件框架。通过锁存器和端口扩展芯片完成单片机的数据端口扩展与控制,设计了交通信号控制过程。从而实现对业务信号的控制。单片机控制交通灯。

The hardware framework of traffic signal lamp is introduced. The data port expansion and control of MCU are accomplished by latch and port expansion chip, and the traffic signal control process is designed. Thus the control of business signals can be realized. Single chip computer controls traffic lights.
