Abstract
The LCD manifestation has been the key technique of the man-machine interface. This text to basic proceeded the research in Micro Controller Unit liquid crystal display control system. Introduced the lesson a background of this lesson and study meaning and finished functions in introduction first. This system edits collected materials the language to proceed with single the basic language of a machine the software designs, the instruction carries out the speed quick, save memory. For the sake of easy to expand with the design adoption mold a logic for turning construction, making procedure designing relation that change, software more shorter and more easier to understand. Make hardware control in software descended to moderate the operation. The text inside describes the system hardware work principle in brief first, and attach with the system hardware design frame diagram, combine development history that introduced the single a machine microprocessor, discuss this graduate design a function for applied each hardware connecting a people the technique connects with each one a mold piece and work processes, combine to describe in a specific way 8052,8279 and the SED1520 circumscribes the electric circuit connects oscular and soft, the hardware adjusts to try. Expatiated the process of the procedure the next in order with realizes process. The predominance thought that this text compose is soft, the hardware combines together, regarding hardware as the foundation, proceed the plait of each function mold piece write. Develop to me finally of use the single a machine realizes the design thought that the liquid crystal display of LCD control principle with soft, the hardware adjusted to try to make the detailed treatise.
