摘要
本文设计了一款低功耗的记秒器系统,系统以单片机为核心,辅以复位按钮、动态数码管显示器、74LS13译码器等构成了一个硬件系统,并利用单片机的定时中断,显示函数和键盘函数等,实现了一个具备清零记秒功能、暂停停止记秒、重新观看之前N个记秒数据和记录N个记秒时间的记秒器系统,且系统能在1个小时不使用后自动进入到休眠状态.
This paper designs a low-power stopcock system,which is based on single-chip computer,assisted by reset button,dynamic common-negative digital tube display,74LS13 decoder and so on,to form a hardware system. By using the timing interrupt of single-chip computer,display function and keyboard function,a clear system is realized. The seconds system can automatically enter a dormant state after one hour of non-use,with characteristics of zero seconds function,pause stop counting seconds,N seconds data before re-viewing and recording N seconds time counting.
