VC_MFC-Sample1
Microsoft Visual C++ MFC串口通信编程详解,主要介绍了用CreateFile()函数和WriteFile()函数读写串口的实例,以及设置
串口属性的实例.
在工业控制中,工控机(一般都基于 Windows 平台)经常需要与智能仪表通过串口
进行通信.串口通信方便易行,应用广泛.
一般情况下,工控机和各智能仪表通过 RS485 总线进行通信.RS485 的通信方式是
半双工的,只能由作为主节点的工控 PC 机依次轮询网络上的各智能控制单元子节点.
每次通信都是由 PC 机通过串口向智能控制单元发布命令,智能控制单元在接收到正
确的命令后作出应答.
(Microsoft Visual C++ MFC serial communication programming explain CreateFile () and WriteFile () function to read and write the serial port of the instance, and set the serial port attribute instance in industrial control, IPC (generally based on the Windows platform) often need to communicate with the smart meter through the serial port serial communication easy and widely used normal circumstances, the IPC and intelligent instrument through RS485 communication RS485 communication is half-duplex, only as the primary node industrial PC turn polling network intelligent control unit child nodes. every communication from a PC via the serial port to issue commands to the intelligent control unit, intelligent control unit receives the correct command response.)
