单片机控制系统和微机系统之间通信的几个技术问题

Several technical problems about communication between embedded microcontroller system and PC system

为了解决多CPU结构单片机控制系统在调试模块通信方面的困难 ,提出了一整套实现单片机系统和微机系统之间串行通信的软、硬件设计方案。通过接口转换器实现双方电平转换 ,单片机使用中断方式控制通信 ,微机使用VB编程 ,并采用通信保护电路 ,大大增强了通信的可靠性 。

In order to solve the difficulties in debugging the communication software among modules of the embedded microcontroller system with multi CPU structure,an integrated scheme of software and hardware design for realizing the serial communication between PC system and embedded microcontroller is presented.The interface converter is used for voltage level conversion,the interruption mode is used for communication control in the embedded microcontroller system,the VB is used for PC system programming,and the communication protection circuit is adopted.All these greatly enhance the reliability of communication and simplify the debugging procedure.
