Using VC++6.0 to implement serial port data exchange between PC and single-chip microcomputer [Copy link]

Serial communication issues are often involved in the field of industrial control (such as DCS systems). In order to realize data exchange between microcomputers and single-chip microcomputers, people use various methods to realize serial communication, such as assembly language or C language under DOS , but there are some difficulties and shortcomings under Windows environment. Under the situation that Windows operating system has occupied a dominant position (not to mention that some systems do not support DOS at all, such as Windows2000 ), it is increasingly important to develop serial communication technology under Windows environment. VC++6.0 is a development environment launched by Microsoft in 1998. It is favored by software developers for its powerful functions, friendly interface, 32-bit object-oriented programming and flexibility of Active X, and is widely used in various fields. There are currently several methods for developing serial communication using VC++ : one is to use Windows API communication functions; the second is to use VC 's standard communication functions inp , inpw , inpd , outp , outpw , outpd , etc. to directly operate the serial port; the third is to use Microsoft Visual C++ 's communication control ( MSComm ); the fourth is to use the communication class written by a third party. Among the above methods, the first one is widely used, but it is more difficult to use because it is more complicated and highly specialized; the second method requires understanding of the hardware circuit structure principle; the third method seems simpler and only requires simple configuration of the serial port, but it is not very easy because it uses the confusing VARIANT class; the fourth method is to use a CSerial class for serial communication (this class is provided by a third party), which can be used . The author used the CSerial class to easily realize the communication between the partition starter (single-chip microcomputer system) of the fixed EBM aerosol fire extinguishing system and the host computer. The following will combine examples to give several methods to achieve serial communication

Thanks to the original poster. I have been looking for this kind of stuff. I have done it for a while in school before, but my foundation is too poor. When I saw this topic, I couldn't help but come in. . .
