在电子技术中,频率是最基本的参数之一,又与许多电参量的测量方案、测量结果都有十分密切的关系,因此频率的测量就显得更为重要。测量频率的方法有多种,其中电子计数器测量频率具有精度高、使用方便、测量迅速,以及便于实现测量过程自动化等优点,是频率测量的重要手段之一。在本次毕业设计中我们选择使用单片机来制作数字频率计,并在实际制作中采用了直接测频法。利用延时产生的时基门控信号来控制闸门,通过在单位时间内计数器记录下的脉冲个数计算出输入信号的频率,最终送入LCD中显示。这样制作出来的频率计不仅可以满足设计题目的参数要求,而且具有了单片机的稳定性和成熟性,且控制能力强,是一种低成本,高可靠的设计方案。-In electronic technology, the frequency is one of the most basic parameters, but also with a number of electrical parameters of the measurement program, the measurement results have a very close relationship between the frequency of measurement, therefore it is even more important. Measurement of the frequency of a number of means, electronic measurement of the frequency counter with high precision, easy to use, rapid measurement, and measurement is easy to realize the advantages of process automation is an important means of measuring the frequency of one. Graduates in this design we have chosen to make use of single-chip digital frequency meter, and used in the actual production of a direct

Serial-Comunication.tar
windows系统下汇编语言实现的串口聊天小程序,具有简易的聊天界面,支持聊天记录保存,使用中断及查询方式实现,支持二进制和字符传送。
1. 文件功能描述:
1com1.asm为打开com1通信的源文件
2com2.asm为打开com2通信的源文件
2个源代码除了串口地址不同,其他代码相同
同理1com1.exe 和2com2分别打开com1和com2来通信
2. 二进制传送格式:
当选择菜单二进制传送时(菜单2和3)
发送方输入以空格隔开的2位的16进制数,(不够2位用0补充)
比如可以输入 AB CE 33 3F EC 01 00 0A 再按回车就发送过去了。
(windows system the serial assembly language chat applet with a simple chat interface, support chat history saving, the use of interrupt and query method implemented to support binary and character transfer.
1. File Function Description:
1com1.asm communication to open the source file com1
2com2.asm communication to open the source file com2
2 In addition to the serial port address of the source code is different from other code the same
Similarly 1com1.exe and 2com2 open com1 and com2, respectively, to communicate
2. Binary delivery format:
Binary transmission when the selection menu (Menu 2 and 3)
Enter the sender of the two separated by a space of 16 hexadecimal numbers (not supplemented with 0 2)
For example you can enter AB CE 33 3F EC 01 00 0A press Enter to send over.)
