摘要
以单片机89C51为核心设计了一种频率计。在设计中应用单片机的数学运算和控制功能,实现了测量量程的自动切换,既满足测量精度的要求,又满足系统反应时间的要求。
In this paper,an intelligent cymometer based on a microcontroller is designed.By making full use of the processor 89C51,it can switch automatically among different ranges to meet the needs for high accuracy and short measuring time.
