2、S=0;RW=0;E=1;P0=com;delay(5);E=0;delay(5);}voidwrite_date(unchardate){busy();RS=1;RW=0;E=1;P0=date;//delay(5);E=0;//delay(5);}voidinit(){delay(2000);write_com(0x30);//选择基本指令，选择8位数据流delay(5);write_com(0x0c);//开显示（无游标，不反白）delay(10);write_com(0x01);//清除显示，并且设定地址指针为00

3、Hdelay(500);write_com(0x06);//设定游标移动方向}voidsendaddr(uncharn,uncharm){switch(n){case1:write_com(0x80+m);break;case2:write_com(0x90+m);break;case3:write_com(0x88+m);break;case4:write_com(0x98+m);break;}}voiddisplay(uncharn,uncharm,unchar*s){sendaddr(n,m);while(*s>0)
