利用28335的cpu-timer0的中断功能进行AD采集，并有AD校核程序(Use cpu-timer0 interrupt functions of 28335 AD acquisition, and checking procedures AD)

89c52的串口通信的演示 (89c52 serial communication demonstration)

根据对应的按键值，对应输出相应的电容值，并做掉电检测(According to the corresponding key value, corresponding to the output of the corresponding capacitance values ​ ​ and do brownout detection)

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))

新中新小一卡通标准对接服务SDK，拥有它完全可以自行定制业务软件(The Synjones ConCard TPE SDK)

一个电表行业专用的基于645规约的电表485通讯抄表程序，可以进行485总线抄表，645规约测试。程序技术要点就是规约数据传输协议的处理，如向电表发送数据时的控制码和数据长度、发送的数据部分(数据标识 + 密码 + 数据)、应答帧长度、结束标志等通讯协议的处理值得大家学习。(A meter-based industry-specific statute 645 meter 485 meter-reading procedure can be carried out 485 meter, 645 Statute of the test. Procedures for the technical elements of the statute is to deal with data transmission protocols, such as sending data to the meter when the control code and data length, send the data section (data logo+ Password+ Data), response frame length, marks the end of the treatment protocol, etc. everyone deserves to learn.)

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.)
