用Turbo C编写的一个串口操作小程序，能发送，接收信息；程序功能简单，过段时间再把经过修改后的版本传上来(using Turbo C serial prepared by a small operational procedures, send, receive information; Functional procedures simple, then over time, after revision line with the traditional version.)

通信历程，可选取合适的串口号、波特率等实现通信(It is an communication process, you can choose the appropriate serial number, baud rate and so on to achieve communication.)

C++串口通信代码，接收下位机的数据点，并在前面板画出图形。（数据格式* , , /）内附STM32串口发送数据程序(C++ serial communication code, receive under the data points, and the front panel to draw graphics. (Data format,*, /) containing STM32 serial transmit data program)

说明：  自制上位机，可以完成发送接收，测试可用。(Homemade PC can complete sending and receiving, and test is available.)

C8051芯片的I2C总线控制程序，包含五段代码（读写EEPROM,主控读写单字节，多字节，被动读写单字节，多字节）(C8051 chip of I2C bus control procedures, including five sections code (reading and writing EEPROM, master literacy single-byte, many bytes, passive literacy single-byte, multibyte) )

利用面向对象的C++语言的MFC编写的串口通信程序(The use of object-oriented language C++ MFC prepared by the serial communication program)

说明：  台达校验码是ASCII的，VB源码。网上大部分是RTU的(Delta check code is ASCII, VB source code.Most of the Internet is RTU.)

简单的串口通信数据显示demo 简单实用 可以学习查看(A simple serial communication data display demo simple and practical Can learn to see)

西门子S7-200 与opc软件KEPServerEx的 通讯设置过程(Siemens S7-200 communication set-up process)

说明：  通过串口对温湿度检测，实现对温湿度的检测和读取(The temperature and humidity can be detected and read by serial port.)
