针对传统单片机实验教学存在的多种问题,提出利用仿真软件Proteus和Keil进行虚拟实验教学的方法。以“矩阵键盘调节数码”实验为例,详细说明了基于仿真软件的虚拟实验具体实施过程,包括硬件电路设计、软件程序编译及调试。实践表明,基于仿真软件的虚拟实验能够实现实验具体要求,与实际电路结果相符,可作为传统实验的有效辅助手段。
Aiming at many kinds of problems existing in the traditional MCU teaching, this paper puts forward the method of virtual experiment teaching using the simulation software Proteus and Keil. In this paper, the experiment of adjusting the digital matrix with "matrix keyboard is taken as an example, the process of virtual experiment based on simulation software is described in detail, including hardware circuit design, software program compilation and debugging. Practice shows that the virtual experiment based on simulation software can meet the specific requirements of the experiment and is consistent with the actual circuit results, which can be used as an effective aid to the traditional experiment.
