cpu314c-2pn_v3

本程序是关于串口通信，已经调试通过，希望对大家有所帮助。(RS485)

232通信全部程序，包含头文件与相应的主程序，很全的232通信程序(232 exchange)

合众达提供的两个驱动，可以添加自己的算法。一个是串口的，一个是实时系统的。(America to the two drivers, they can add their own algorithms. 1 serial port, a real-time system.)

说明：  自己编写的变异的modbus，先分享给大家(the modbus by myself,now give all)

MSComm控件串口通信编程，第一次作业。(MSComm control serial communication programming, the first operation.)

串口通信高级编程，为Visual C++.NET网络与通信高级编程范例第八章配套源代码 (serial communication programming, for Visual C.NET network and communications senior programming paradigm Chapter VIII supporting source code)

说明：  用数据库实现串口通讯的源代码，功能比较强大，值得一看。(database using serial communication source code, functions more powerful overseas.)

说明：  支持9600，19200等常用各种波特率及自定义波特率，可以自动识别串口，能设置校验、数据位和停止位，能以ASCII码或十六进制接收或发送任何数据或字符，可以任意设定自动发送周期,并能将接收数据保存成文本文件，能发送任意大小的文本文件。 硬件连接方面，传统台式PC机支持标准RS232接口，但是带有串口的笔记本很少见，所以需要USB/232转换接口，并且安装相应驱动程序。(Support 9600, 19200 and other commonly used baud rates and custom baud rates, can automatically identify serial ports, can set check, data bits and stop bits, can receive or send any data or characters with ASCII code or hexadecimal, can arbitrarily set the automatic transmission cycle, and can save the received data into text files, can send any data. Text files of meaning size. In terms of hardware connection, traditional desktop PC supports standard RS232 interface, but notebooks with serial port are rare, so USB/232 conversion interface is needed and corresponding driver is installed.)

说明：  此程序为多线程,多接收模式串口类，程序很全，适合新手学习，同是也可以根据自己的兴趣添加自己感兴趣的各个功能(This program is multi-threaded, multi-category serial receive mode, the program is very full, for beginners to learn, the same can also add your own according to their interest in the various features of interest)
