Interface Design of LCD Touch-display Terminal and SCM

Hou Ting

Abstract

The command functions is elaborated after the analysis of performance characteristics and controlling modes of LCD touch-display terminal.With AT89C51 microcontroller as the core,CPU is connectted with LCD touch-display terminal through RS232 serial port.The method of generating the graphics displaying man-machine interface by LCD touch-display terminals is described.The control of color LCD touch-display is achieved through system control commands issued by CPU.The methods of testing and controlling the touch-button are illuminated.The principle of interface circuit of SCM and LCD terminal,the design method of the major controlling program and program design of the main functions are given.The selection of LCD screens,drivers and complex software programming in the course of the application of large dot-matrix LCD displays in the microprocessor is settled down.
