说明：  本工程利用STM F103zet生成SPWM波(this project use stm32 h103zet create spwm wave)

使用SMT32F103做的一款用于雾霾检测的板子(A board made of SMT32F103 for haze detection)

伺服电机控制系统，02年开始积累，效果好，速度快，PI控制，经典控制，fuzzy PID，自适应控制，速度位置控制等等，欢迎大家参考。(Servo motor control system, in 2002 began to accumulate, effective, fast, PI control, classical control, fuzzy PID, adaptive control, speed position control, etc., we welcome the reference.)

功率单元串联型高压变频器模型，8个单元10kv系统，载波移相实现方法(High-voltage inverter power unit in series model, eight units 10kv system, the carrier phase shift method to achieve)

内涵STM8S的库，集成个人修改的文件 已经检验(Library of Connotation STM8S)

测量频率的低电平保持时间，用来测量汽车喷油嘴喷油的时间，单位ms(The low level holding time of measuring frequency is used to measure the injection time of automobile nozzle, unit Ms.)

基于AT89S52设计的超声波测距电路，有4路距离警报灯和蜂鸣器报警电路，并有警报输出接口。资料，中包括程序源代码和原理图，其中原理图是用protel99做的。(AT89S52 based on the design of ultrasonic distance measurement circuit, a 4-way distance warning lights and buzzer alarm circuits, and alarm output interface. Information, including source code and schematics, which is schematic protel99 do.)

STM32单片机利用DS18B20温度传感器实现温度检测的源码，包括原理图和数据手册(The STM32 MCU DS18B20 temperature sensor temperature detection of the source, including schematics and datasheets)

本程序利用51单片机的定时器中断产生时间信号，同时具有通过按键调节时间的功能，还可设置闹钟(This procedure using 51 single-chip timer interrupt time signal, but also has the functions via buttons adjust the time, but also set the alarm)
