It is playing an important role in building enterprise information systems. It features powerful functions, ease of use, and fast code execution. Delphi is a new-generation object-oriented visual development tool. The communication between the PC and the lower computer can be implemented through advanced programming languages, such as Delphi and VC. 350 yuan mcu development system 498 yuan carefree MCU Experimental Development Board 238 yuan Because of the high performance and price ratio of the microcomputer, strong analytical processing ability, fast processing speed, strong anti-interference ability of the single chip microcomputer, and flexible use, the PC is used as the host computer, single-chip microcomputer is widely used as the master-slave mode in industrial control. An example is provided to show the application of Spcomm Control in Delphi7.0 serial communication.Īt present, with the development of modern information technology, computer serial communication technology has become increasingly mature. Based on the analysis and comparison of several common serial communication methods, this paper focuses on the use of the Spcomm Control in the Delphi development environment to achieve serial communication between PC and single chip microcomputer, the key technical problems of Spcomm serial communication are studied. Abstract: The use of Delphi to develop industrial control system software has become the choice of more and more developers, and serial communication is one of the problems that must be solved in this process.
