Abstract

Study on the design approach of the main control program of single chip microcomputer and serial control liquid crystal display module

Author(s): Yuhan Wang

The study carried out deep analysis on the main control program of SCM and serial control LCM and discussed the function of some control commands. Adopting single chip microcomputer AT89C51 as the core component, the system CPU connected to the LCD touch-display terminal and sent control commands through the RS 232 serial port. Besides, the study specifically introduced the design scheme and control method of the main control program of SCM and serial control LCM. The system mainly realizes the control of color touch LCD through special control module. The basic principles of the connection between modules and the design, implement method and main functions of critical control module are also detailedly described in the paper. The main control program of SCM and serial control LCM can resolve many software programming difficulties of the original system. Due to the rapid development and wide use of microelectronic technology as well as the increasing automatic and intelligent equipment, the system program puts out high request on operators, therefore the man-machine interaction interface of system becomes more and more important. The study also specifically introduced the practical value, characteristics, operation method, and operation process of the main control program of SCM and serial control LCM and described the application method of simulation testing software, the method of using it to produce graphical display interface and the display method.. Finally, the paper expounded the design approach and implement method of the simulation module in the main control program of SCM and serial control LCM
