1、液晶显示（所有程序都经过测试合格）一、基础部分。（以 1602 与 12864 介绍）本部分以液晶1602 为主，来引出关于单片机操作液晶的基本知识。为以后液晶的高级应用打好基础。、本程序最终目的为：显示一个双行数字，并实现整屏移动。总的原理图及源程序如下：原理图：液晶电路图 液晶显示.ddb源程序：液晶例程液晶显示.c#include#define uchar unsigned char#define uint unsigned int uchar code table=I LIKE MCU!;uchar code table1=WWW.TXMCU.COM;sbit lcdwr=P25;/R
