这个是C++编程实例100篇，里面包含有100个工程实例用于学习(C++ Programming Example 100)

这是基于单片机设计了一款PLC系统，有详细的梯形图到汇编语言的转换(This is based on a single-chip design of the PLC system, a detailed Ladder to assembly language conversion)

永磁同步电机无传感器矢量控制方法研究及仿真(Research sensorless vector control methods and simulation of permanent magnet synchronous motors)

说明：  光伏发电系统三相逆变并网及其仿真研究，论文详解。(Study on three-phase inverter Grid connection and its simulation of photovoltaic power generation system)

单片机与PC机串口程序，pc机用串口调试工具发送16进制数据到单片机，单片机再返回一个接受到的信号回pc机，(SCM and PC serial port procedures, PCs with serial debugging tools to send 16-band data to a single chip, the microcontroller return to a finer signal to PCs,)

说明：  磁保持继电器通断测试程序，采用AT89S51控制。(Magnetic self-perpetuating relay-off test procedure, using AT89S51 control.)

本源码程序为射频通信驱动代码，采用IAR system软件开发，以MSP430单片机为主控芯片，程序集成了CC1120，CC1200，CC1101等多种射频芯片，在使用时可通过用户自己屏蔽不需要的芯片，程序中均已文件分好，各种芯片的代码互不干扰。我已经通过测试，改程序可以直接运行，但用户在使用时需进行IAR软件的路径配置(The source program for RF communication driver code, using the IAR system software development, MSP430 single chip as the main control chip, the program integrates CC1120, CC1200, CC1101 and other radio frequency chip, by the users themselves do not shield chip when in use, the program have the good, various chip code do not interfere with each other. I have passed the test, reform program can be run directly, but the path to configure user required when using IAR software )
