基于51单片机液晶1602的移屏显示

//液晶1602数据接51单片机P0口，rw直接接低电平 //移屏显示字符串（左移） 竣工 搞定 // 2009.8.11 #include<reg52.h> #define uchar unsigned char #define uint unsigned int sbit rs=P2^5; sbit e=P2^7; uchar table1[]="dianzizhizuo"; uchar table2[]="I love you"; void delay(uint x) { uint a,b; for(a=x;a>0;a--) for(b=10;b>0;b--); } void write_com(uchar com) { P0=com; rs=0; e=0; delay(10); e=1; delay(10); e=0; } void write_date(uchar date) { P0=date; rs=1; e=0; delay(10); e=1; delay(10); e=0; } void init() //初始化,控制命令 { write_com(0x38); delay(20); write_com(0x0c); delay(20); write_com(0x06); delay(20); write_com(0x01); delay(20); } void main() //主函数显示 { uchar a; init(); write_com(0x80+10); delay(20); for(a=0;a<12;a++) { write_date(table1[a]); delay(200); } write_com(0xc0+10); delay(50); for(a=0;a<10;a++) { write_date(table2[a]); delay(400); } for(a=0;a<8;a++) { write_com(0x18); delay(2000); } while(1); }
