单片机系统中的数码管秒表仿真研究

摘要

给出了单片机数码管秒表的原理框图，分析了数码管秒表的设计思路。采用PROTEUS软件绘制出了单片机数码管秒表仿真原理电路图，编写出完整的汇编语言源程序。运用PROTEUS 和KEIL软件加载程序，对单片机系统实现数码管秒表的过程进行了仿真。仿真结果表明，设计的数码管秒表能实现和真实秒表一样的显示效果。%Absract:The schematic diagram of digital tube stopwatch was given in this paper,and the design proposal of the stopwatch was analyzed.Using Proteus software to draw the circuit simulation diagram of the stopwatch, and writing out the source codes written by assembly language.The realization process of digital tube stopwatch was simulated by using Proteus and KEIL software loading program to MCU system.The simulation results showed that the designed digital stopwatch could realize the same demonstration effect as the real stopwatch.
