液晶显示模块WM-C1602N与单片机接口设计

Designing of LCD Module WM-C1602N and SCM Interface

主要介绍液晶显示模块WM-C1602N、非编码键盘与M-C51系列单片机的接口电路设计,实现键盘扫描、液晶显示模块显示的功能。本文阐述硬件设计原理和软件设计方法,并给出了WM-C1602N与单片机接口的电路原理图和部分程序。

The liquid-crystal Display （LCD） used WM-C1602N as the example is showed in this paper to finish the design of interface of single chip microcomputer, liquid-crystal Display and keyboard.Thus,they realize the function that keyboard scan and LCI） show the correspond number when the key is pressed.The design principle of hardware and the design method of software are discussed.The detailed circuit principle graph and the part of the assembly language programme for realization are given.
