為什么仿真就下面一道杠，不動態(tài)顯示
#include<reg51.h>
#define uint unsigned int
#define uchar unsigned char
uchar code table[]="hello everyone!";
uchar code table1[]="welcome to here!";
sbit lcden=P3^4; //液晶端使能
sbit lcdrs=P3^5; //液晶數(shù)據(jù)命令選擇端
uchar num;
void delay(uint z)
{
uint x,y;
for(x=z;x>0;x--);
for(y=110;y>0;y--);
}
void write_com(uchar com)
{
lcdrs=0;
P2=com;
delay(5);
lcden=1;
delay(5);
