Open publisher page 0 citations

Abstract

Dot-matrix LCD makes a feature of low power dissipation,small volume,and displaying more information,also widely used in automatic instrument.To provide more better user interface, dot-matrix LCD is used as a displayer.The interface circuit for dot-matrix LCD with MCS-51 singlechip microcomputer and the design of software corresponding are described in detail.Meanings of sixteen signal wires of a port is explained.the initial program of LCD is given,and the principle of Chinese charater and menu display is introduced. The hardware design of speech terminal is simple with a LCD module,while the user interface is more beautiful with the technology of chinese character and menu display. The adjustment of LCD contrast is discussed,and the solution is given.
