摘要
单片机具有集成度高,体积小可靠性好和性价比高得优点,该文主要阐述了设计一个利用单片机作为总控制中枢的秒表系统。利用单片机可以定时和记数的原理结合时钟电路、数码管显示电路、复位电路和按键电路将软、硬件同时结合起来,使得系统能够准确无误地进行计时,同时具有开始,暂停,清零和复位的功能。
MCU with integration of small size, high reliability and high ratio of performance to price advantages, this paper mainly expounds the design using a single chip microcomputer as the total central control of the stopwatch system. The use of singlechip can timing and counting principle in conjunction with the clock circuit, digital tube display circuit, reset circuit and the key circuit software and hardware combined together, which makes the system can accurately correct timing, also has a start, pause,clear and reset function.
