This paper studied the MCU control system based on LCM liquid crystal display module. The first chapter introduces the subject background of the topic, research significance and function. This system on software design based on C language, the instruction carries out the speed quick, save storage space. In order to facilitate the expansion and the change, the software design uses the modular structure, make the logic?relation of program design more concise. The hardware to coordinate the operation under the software control. The text first briefly describe the working principle of the system?hardware, and attached to the system hardware design block diagram, and introduces the history of the development of microprocessor, and discusses the function and working process of the graduation design, the application of the hardware interface technology and the interface module, and the concrete description of AT89C52: single chip microcomputer; LMO16L:16 * 2 character LCD display; secondly describes the process flow and implementation process. The main idea of this writing is soft, a combination of hardware, hardware based, prepared to carry out every function module. Finally, I developed with MCULCD LCD control design principle and soft, hardware debugging in detail.Key words：AT89C52: single chip microcomputer; LMO16L:16 *2 character LCD display目 录 TOC \o "1-2" \h \z HYPERLINK \l "_Toc375772101" 第1章引言 PAGEREF _Toc375772101 \h 1 HYPERLINK \l "_Toc37577210
