VB和信捷PLC通讯的源代码，包括读写，置位，独一无二哦，网上都找不到的。(vb and thinget plc communication program source,good thing)

该源码公示了怎样使用STM32F407的串口进行收发数据，在keil5编译环境中进行编译。需要将STM32F407的串口1与USB串口相连，即可以实现电脑桌面串口调试助手的调试。(The source of the public how to use STM32F407 serial port to send and receive data, compiled in keil5 compilation environment. We need STM32F407 serial port 1 is connected to the USB port, which can achieve desktop debugging serial debugging assistant.)

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.)

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：  关于多块板子利用485总线 采用MODBUS协议实现开关量采集与控制采集，串口打印。(On the use of 485 bus and MODBUS protocol to realize switch data acquisition and control acquisition, serial port printing.)

vc_串口通讯，介绍了如何用VC实现串口通信的原理和源程序(vc_ serial communication, describes how to use the VC to achieve the principle and source of serial communication)

串口调试工具，加油(serial debugging tools refueling.)

说明：  用labwindows和PLC联合编写的串口通信程序，利用PLC做数据采集卡，在labwindows中编写串口通信显示程序。(Prepared jointly by labwindows and the PLC serial port communication program, the use of PLC for data acquisition card, write the serial communication in labwindows display program.)

利用C语言实现RS232串口上下位机通信的设计(Using C language to realize RS232 serial port communication up and down a machine design )

通过调用API函数实时采集来自串口的数据,并将数据实时显示在界面中(function: sample data come from serio port and display information in form)
