This Micro Controller Unit liquid crystal display. It firstly introduces the background, meaning and functions achieved of this program in introduction. This system designs by assemble language which is basic language of single-chip microcomputer. It makes instruction carry out with quick speed, and saves memory. For the sake of easily expanding and change, design is applied to the frame of blocking, which makes logic easier to understand. Make hardware more moderate operate with the software control. First, the paper describes working-principle of system hardware in brief, and attaches to the system hardware frame diagram, and then introduces the history of single-chip microcomputer, discuss the technology of hardware interface and functions and work process of interface module. It describes in a specific way 89C51 and the SED1335 circumscribes the circuit connecting and soft, the hardware adjusts. Told about procedure that how to realize it. The predominance is that soft and hardware combine together, regarding hardware as the foundation, proceeding program every functional modular.
