pid controler 程序比较简单，但比较实用 大家可以(pid controler procedure is relatively simple, but we can compare utility)

220VAC的EMC滤波电路，加220AC转12VDC(220VAC EMC filter circuit, plus 220AC to 12VDC)

信号滤波，使用在AVR. 串口接收数据格式 0xFFFF+数据位。(Signal filtering, the use of the AVR. Serial receive data format 0xFFFF+ Data bit.)

取硬盘温度源码例程，程序创建WbemScripting.SWbemLocator对象实现取硬盘温度和使用时间功能。(Take the hard disk temperature source routines , the program creates WbemScripting.SWbemLocator object implementations take time and hard disk temperature function .)

基于单片机的智能家居系统：红外遥控，红外报警 ，光与LED灯，串口显示光信息 ，时间显示，电机正转，，电机反转，温度报警 (Microcontroller-based Smart Home System: Infrared remote control, infrared alarm, light and LED lights, serial optical information display, time display, the motor is transferred, motor reversal, temperature alarm)

三星S3C44B0X的I2C总线功能模块测试，该程序实现了的各种读写操作，硬件调试通过(Samsung S3C44B0X the I2C bus function module test, the program has a variety of read and write operations, hardware debugging through)

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.)
