[Other resource单片机频率计

Description: 此频率计是用单片机89C51和几块数字电路几个三极管,和一个微波集成电路构成。可测量频率最高为2G!分辨力为1HZ!电路中R16---R27电阻阻值为1K。这文件包里有两符制作成功后的图片! 二个SCH。一个PCB文件。一个PDF文件。和一个程序HEX文件。制作的时候只要按线路板接好元件,然后把程序HEX文件烧写到单片机内,就可以调试了,希望大家成功。其中高稳定振荡电路SCH文件是我新加上的。如果大家有条件用上这电路也不错。那样频率计将更稳定。频率计的PCB是我设计的。 设计得不太好,希望大家多多提出意见和建议。希望大家不要修改PCB文件。 注:解压密码deyiluntan-this Cymometer is 89C51 microcontroller and a few digital circuit several triode, and constitute a microwave integrated circuits.

These high stability oscillation circuit SCH document is a new addition. If we conditional use this circuit is a good one. As the frequency of dollars will be more stable. Frequency of PCB is my design. Design it very well, we hope that many opinions and suggestions. We should not amend the PCB document. Note : extracti

Description: 低频频率计 实例目的:学习定时器、计数器、中断应用 说明:选用24MHz的晶体,主频可达2MHz。用T1产生100us的时标,T0作信号脉冲计数器。假设晶体频率没有误差,而且稳定不变(实际上可达万分之一);被测信号是周期性矩形波(正负脉冲宽度都不能小于0.5us),频率小于1MHz,大于1Hz。要求测量时标1S,测量精度为0.1%。-Examples of low-frequency frequency meter Objective: To study timer, counter, interrupt Application Note: optional 24MHz crystal, frequency up to 2MHz. 100us generated by the T1 time scale, T0 for the signal pulse counter. Assuming there is no crystal frequency error, and stable (in fact up to one ten thousandth) the measured signal is periodic rectangular wave (positive and negative pulse width can not be less than 0.5us), the frequency of less than 1MHz, greater than 1Hz. Requested measurement time scale 1S, measurement accuracy of 0.1.
