| Abstract: | This paper introduces a solution of serial communications in Distributed Control System(DCS) which uses 89C52 single-chip microprocessor as down processor and PC computer as up processor and they are connected by 89C52 single-chip microprocessor communication controller. The programming techniques of serial communications that how to realize the serial communications by using Platform Invocation Services to invoke the unmanaged win32 API serial communications DLL codes in Common Language Runtime(CLR) environment, by combining with multi-thread/event handler/synchronization access technology are studied in .NET platform. This paper also discusses the programming techniques of serial communications of single-chip microprocessor by taking a programming sample. |
