摘要
介绍了一种基于80C51单片机的教学演示板设计,应用具有键盘控制和显示功能的芯片8279,实现了键盘选择功能模块、时钟显示、发光二极管显示对应的P1口输入等功能。通过ADC0804芯片实现了模数转换功能,并给出了演示板的电路原理图及软件流程图。在应用Proteus进行仿真实验的基础上,成功调试了演示板的各项功能。实验证明,较其他单片机教学演示板,该演示板结构简单、设计思路清晰、功能针对性强且便于学习理解。
The paper introduces the teaching demonstration board design by 80C51 SCM. The chip 8279 withkeyboard control and display functions is used to achieve the functions of the keyboard selection, clock display andlight-emitting diode display corresponding P1 input. And the board achieves the Analog-digital conversion functionwith the demonstration board circuit schematics and software flow chart given. Based on Proteus simulation experi-ments, debugging of the various functions of the demonstration board is performed. Experiments show that comparedwith other single-chip teaching demonstration board, the proposed board has simple structure, and specialized func-tions, and is easy to learn and understand.
