if(KEY2==0){while(KEY2==0);stat=1;}
break;
case 2:lcd_write_string(str2);
if(KEY1==0){while(KEY1==0);stat=3;}
if(KEY2==0){while(KEY2==0);stat=1;}

case 3:lcd_write_string(str3);

case 4:lcd_write_string(str4);
if(KEY1==0){while(KEY1==0);stat=1;}
if(KEY2==0){while(KEY2==0);stat=3;}
break;
default:break;
}
}
}
按KEY1，KEY2 是能实现上下翻显示，但显示不稳，不停的闪，如何解决？
