本文介绍了AT89C52单片机与PC机串行通信的虚拟仿真实现方法,利用虚拟串口软件VSPD搭建虚拟的串行通讯线路,利用VB6.0进行上位机界面设计和其中的通信控件MSComm实现PC机端的串口通讯,利用PROTEUS实现单片机的串行通讯与控制程序。系统经过实际运用,既节省实际硬件资源,又能达到直观良好的效果。
This article describes the AT89C52 microcontroller and PC serial communication virtual simulation method, the use of virtual serial port software VSPD to build a virtual serial communication lines, the use of VB6.0 PC interface design and communication control MSComm PC-side serial port Communication, the use of PROTEUS SCM serial communication and control procedures. After the actual use of the system, not only save the actual hardware resources, but also to achieve intuitive and good results.
