STC15单片机驱动LCD12864，并且是使用串口通信协议，节约IO口，亲测可用(STC15 microcontroller driven LCD12864, and you are using serial communication protocol, save IO ports, pro-test available)

自动交通控制系统用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下： 1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。 2）禁示线：红灯亮禁止30秒，然后绿灯亮放行。 3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示）(Automatic traffic control system using red, green, yellow light-emitting diodes, said a total of three traffic lights, the use of single-chip analog time display on a regular traffic signal control and management. Changes of lights to be as follows: 1) Release Line: green clearance 25 seconds, the yellow light warning for 5 seconds, then the red light is prohibited. 2) ban shows lines: the red light is prohibited for 30 seconds, then the green light to release. 3) When the red light in one direction, if the direction of the car through, the alarm speaker sound. (Hit the red signal available 3-5V analog representation))

该工具可以根据输入的UNICODE十六进制字符串计算出相应的汉字或ASCII码。比如：输入4F60便可以得到"你"。(The tool can be based on the input UNICODE calculate the corresponding hexadecimal string guy or ASCII.)

基于单片机STC89C51和74LS164的多功能数字万用表(Based on microcontroller STC89C51 and 74 ls164 multi-function digital multimeter)

C51单片机RTC实时时钟(DS1302)初始时间12：00：00数码管显示(The initial time of the the C51 MCU RTC real time clock (DS1302) 12:00:00 digital display)

上位机，与51单片机进行通信，将从单片机发送过来获得的信息显示在显示界面上。(PC, with 51 single-chip communication, sent from the information obtained from the microcontroller is displayed on the display screen.)
