以C8051F020单片机做的多功能计数器，2008山东大学生电子大赛题目。可以实现频率、周期、时间间隔等测量，可以LCD显示、语音报告结果，并能测试温度、显示时间（DS1302）。-C8051F020 single chip microcomputer to do multi-function counter, 2008 e-Competition topic Shandong college students. Can achieve frequency, cycle, time interval measurement can be LCD display, voice report on the results, and test temperature, indicating the time (DS1302).

测试温湿度以及烟感报警,硬件采用长应8000系列-Test temperature and humidity as well as the Smoke Alarm, hardware should be used long-8000 Series

FlashFlex51微控制器

利用单片机、HD7279、键盘，实现计时器、倒计时器。-The use of single-chip, HD7279, keyboard, realize the timer countdown device.

本设计主要由数字信号发生器和逻辑分析仪组成，其中数字信号发生器运用了89C51单片机系统，可以重复输出8路循环逻辑移位序列，逻辑分析仪用了89C55单片机系统，可以实现8路信号的采集和显示(时间域和空间域)，3级触发字可调，有多种触发功能，可显示时标线,使逻辑分析仪能从大量的数据流中获得有分析意义的数据。-primarily by the design of digital signal generator and logic analyzer, composed of digital signal generator used 89C51 systems, which can output eight repeat cycle shift logic sequence, logic analyzer with the 89C55 microcontroller system, can achieve a 8-way signal acquisition and display (time Victoria and space domain), three adjustable trigger word, a number of trigger functions, can show that the time scale, so the logic analyzer from the large amounts of data flow has been analyzing the meaning of the data.

LCD常用取模软件,还行-LCD common modulus of software, but also line
