單片機+1602液晶顯示設計

忙了一天做了一個1602 顯示的仿真電路和程序 經過調試正常運行！！Success的感覺真好 哈哈.........

現在就把成果分享給大家

本電路程序如下：#includereg51.h>#includestdio.h>#define uint unsigned int#define uchar unsigned charuchar code tab[]="Hello Jary!";uchar code tab1[]="I Love You!";uchar num,len,len1;sbit RS=P2^5;sbit RW=P2^6;sbit EN=P2^7;void delay(uint x){while(--x);}void write_cmd(uchar cmd){RS=0;RW=0;P0=cmd;delay(50);EN=1;delay(50);EN=0;}void write_dat(uchar dat){RS=1;RW=0;P0=dat;delay(50);EN=1;delay(50);EN=0;}void inti_lcd()//1602初始化{EN=0;write_cmd(0x38);//顯示模式設置 設定1602*2顯示 5*7點陣 8為數據入口write_cmd(0x0c);//顯示開關、光標設置 0x0f可以顯示光標write_cmd(0x04);//光標機屏幕顯示設方式置write_cmd(0x01);//清屏write_cmd(0x80);//指針初始化}void main(){inti_lcd();len=sizeof(tab);len1=sizeof(tab1);write_cmd(0x80+0x02);for(num=0;numlen;num++){write_dat(tab[num]);delay(6);}write_cmd(0x80+0x45);for(num=0;numlen1;num++){write_dat(tab1[num]);delay(6);}while(1);        //動態停機}如果需要動態移動還可以再加上一條屏幕移動指令for(num=0;num16;num++){write_cmd(0x1f);delay(8000);}
