Development Of Character Display Based On C8051F MCU

With the development of computer technology and communication technology, the control systems are driven from the DCSs and DFCSs to the open and standardized networked control systems, and character display are tending from the special toward the universal. Character display has functions of operation control, status monitor, parameter set and network communication, gives users friendly interface, replaces the traditional control panel absolutely, therefore it is widely used in textile, printing, pharmacy and water conservancy.Character display which is one of networked control systems nodes is taken as a concrete research object. The universal character display is realized by selecting C8051F310 as hardware core and using Keil to develop software.Firstly, the development process of networked control systems and the application actuality of character display are introduced, then illuminates functions, requirement and architecture of character display. The emphasis of this paper is the design of hardware and software platform and the principle and realization of reconfiguration communication. In the design of hardware platform, the design principle and analysis of hardware module and the design principia of hardware are emphasis; in the design of software platform, the structure design of configuration file, software module design and realization and software optimize are introduced; the theory of reconfiguration communication is applied in the realization of character display, which is other emphasis. It is the aim of this project to develop a universal character display, to explore the co-design of method of software and hardware and to apply reconfiguration communication to practice, which is base to further research in future.The end of this paper is the summary of the whole thesis and the outlook of the next work for this system.
