GPIB

调试串口的程序，本程序运行于PC机，是开发串口电路的好帮手。(Debug serial procedures, the program runs on PC, is to develop a good helper serial circuit.)

说明：  Wincc使用MSComm控件串口通讯，VB中发送十六进制数据(Wincc uses MSComm control to communicate through serial port and sends hexadecimal data in VB)

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)

C#串口通讯，modbus协议样例，数据发送接受(C# serial communication, modbus protocol sample, the data sending and receiving)

说明：  rs485串口简易编程,上位机pc平台windows窗口(RS-485 Transceiver Control)

利用max232，实现51单片机和电脑的通信，使得电脑发一个数据在单片机上用流水灯显示。(Use max232, achieving 51 SCM and PC communications, making the computer sends a data on a single chip with a water light show.)

Windows串口编程 (Windows serial programming)

关于labwindowsCVI的串口程序，很稳定，很全，包含rs232的基本操作。看了很多网上的例子，都不是很好，所以决定给大家奉献一个好的串口程序。(The serial program on labwindowsCVI, very stable, very wide, include rs232' s basic operation. Example, read a lot online is not very good, so I decided to dedicate a good serial program.)

STK是由美国Analytical Graphics公司开发的一款在航天领域处于领先地位的商业分析软件。STK支持航天任务的全过程，包括设计、测试、发射、运行和任务应用(STK is a leading commercial analysis software developed by Analytical Graphics Inc. in the aerospace field. STK supports the whole process of space mission, including design, test, launch, operation and mission application.)
