随着单片机技术的发展,传统的依赖于仿真机的单片机实验成本高且效率低,已不适应现代科技开发需求。串行通信是目前单片机应用中经常要用到的功能,本设计目的就是在传统实验板的基础上,利用功能强大的AT89S52型单片机和编程软件VisualC++设计了一种新型单片机串口通信电路。实验结果表明,该方案接口简单、使用方便、稳定可靠。
With the development of single-chip microcomputer technology, the traditional one-chip computer that relies on the simulation machine has high experimental cost and low efficiency, which is not suitable for the development of modern science and technology. Serial communication is one of the most frequently used functions in SCM applications. The purpose of this design is to design a new type of SCM serial communication circuit using the powerful AT89S52 SCM and programming software Visual C ++ based on the traditional experimental board. Experimental results show that the program interface is simple, easy to use, stable and reliable.
