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

电子钟
利用8253和8259芯片实现实时电子时钟的功能；利用8255控制七段数码管完成定时扫描显示。显示格式为xx时xx分xx秒，每隔1s，时间值改一次。按键SHIFT可选择时、分、秒，按键CTRL可对所选的时、分、秒进行加1，小时加至23后清0，分、秒加至59后清0。(Use 8253 and 8259 chip to realize the function of real-time electronic clock; use 8255 control seven segment digital tube to complete the timing scanning display. When the display format is XX, XX minutes XX seconds, every 1s, the time value changed once. Button SHIFT can choose time, minutes, seconds, button CTRL can be selected time, minutes, seconds added 1, hours added to 23 after 0, minutes, seconds to 59 after 0)
