Gang Hu

Abstract

This paper is based on hardware interface design including LCD touch screen(Model: NB320240R_BIW_SBNH),microcontroller(Model: P89V51RD2FN),touch control chip(Model: RA8806) and LCD driver chip(Model: NT7086),and puts its emphasis on several key technologies of LCD touch screen in the secondary system design.It includes the optimal design and loading of LCD touch screen(NB320240R_BIW_SBNH) driver,the configuration of touch-control registers,the programming of character graphics,the interactive program of LCD touch screen and the interface design technology.It provides a reference for the related design and development.
