基于AT89C51单片机的秒表设计与实现
|
摘要
设计了一种以单片机AT89C51为核心的秒表,从硬件和软件两方面详细介绍了秒表的设计方法。秒表计时范围00.00~60.00秒,精度0.01s。具有"开始、暂停/继续、复位"功能。系统上电,显示"00.00"。按下"开始"按钮,系统计时开始,此时,按下"暂停/继续"按钮,系统停在当前位置,再次按下"暂停/继续"按钮,系统继续计时;如果按下"复位"按钮,系统显示"00.00"。与常规秒表设计相比,此秒表不但设计简单,且其稳定性以及计时精度都有大幅提高。最后通过Proteus软件仿真,验证了该设计的合理性与可靠性。
Stop-Watch based on AT89C51 Microcontroller was designed, introducing design methods in two ways: hardware and software.Stopwatch time range is 00.00-60.00 s, precision is 0.01 s. It has a starting function、 a pause/continuing function and a reset function.When system is on, 00.00 is displayed. When the "start" button is pressed, system timing starts, at this time the "pause/continuing"button is pressed, the system is in the current position, it is pressed again, the system continues to be timed; if the "reset" button is pressed, 00.00 is displayed. Compared to the conventional stopwatch design,the design of the intelligent Stop-Watch is simple、stable and high-precision. The rationality and reliability of the design is proved by proteus-simulation.
