摘要
采用MAX232芯片作为主从式测控系统上位机(PC机)与下位机(单片机)之间的电平转换单元,实现上、下位机正常对接的目的,并通过串口实现上位机与下位机之间的通信。Proteus软件的仿真测试结果表明:该系统能够实现对单片机的电机控制模块和交通灯控制模块的控制。
In master-slave control system,MAX232 chip was used to transform electrical level between PC and MCU so as to link them and to achieve communication between them through serial ports.The simulation with Proteus shows that the system can have testing module(motor control and traffic lights control)function realized.
