如何实现通过串口通讯将数据显示在LCD上，C语言的哦，这是我写的。
#include<reg52.h>
#define uchar unsigned char
#define uint unsigned int
sbit lcdrs=P2^4;//Rs
sbit lcdrw=P2^5;//r/w //
sbit lcden=P2^6;//E
uchar a;
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;
P0=com;
delay(5);
lcden=1;
delay(5);
lcden=0;
}
void write_data(uchar date)
{
lcdrs=1;
P0=date;
delay(5);
lcden=1;
delay(5);
lcden=0;
}
void init()
{
lcdrw=0;
write_com(0x38);
write_com(0x0e);
write_com(0x06);
write_com(0x01);
write_com(0x80);
TMOD=0x20;
TH1=0xfd;
TL1=0xfd;
TR1=1;
REN=1;
SM0=0;
SM1=1;
EA=1;
ES=1;
}
void main ()
{
init();
}
void ser() interrupt 4
{
RI=0;
a=SBUF;
write_data(a);
ES=0;
}
