[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. The maximum measurable frequency for 2G! Resolution of 1HZ! Circuit R16-R27 resistor 1K. This paper bag has produced two successful website after pictures! 2 SCH. A PCB document. A PDF document. HEX and a procedures document. Whenever produced by the PCB then good components, then burning procedures HEX file to SCM, can debug, I hope you succeed. 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
