说明：  在编写程序时，遇到温度检测，则调用读温度软件包(In programming, temperature detection, call packages, read the temperature)

同三维万能采集卡系列开发SDK包,包含例程等! (With three-dimensional universal capture card series development SDK package includes routines, etc.!)

基于STM32的双串口通信程序，能实现两个串口的收发，程序默认采用串口2接收数据，串口1发送(Based on the STM32 dual serial communication procedures, can achieve two serial transceivers, the program defaults to the serial port 2 receives the data, send the serial port 1)

使用方法： 程序设置了ENC28J60的IP为192.168.0.15，模块通电后与电脑的网口用网线连接起来， 设置电脑的本地IP为192.168.0.**（**自定），网关为192.168.0.15,其他默认，配置 成功后便可以arp或ping模块。 打开浏览器，在地址里输入http://192.168.0.15/123456可打开开发板简单网页，页 面上通过按键来控制开发板LED的亮灭。(Use: setup the ENC28J60 of IP to 192.168.0.15, the module is powered on the computer' s Ethernet port using a cable connection up to set the computer' s local IP 192.168.0.** (** Custom), the gateway 192.168.0.15, default configuration is successful, it will make arp or ping module. Open the browser, enter the address http://192.168.0.15/123456 to open the development board simple web pages, and page keys to control the development board LED light off.)

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))
