单片机警告 我就只想用点阵的发光二极管显示一个英文I

#include <REGX52.H>
#define uint unsigned int
#define uchar unsigned char
sbit h1=P2^1;
sbit h2=P2^0;
sbit h3=P2^7;
sbit h4=P2^6;
sbit s1=P2^5;
sbit s2=P2^4;
sbit s3=P2^3;
sbit s4=P2^2;

void delayms(uint xms)
{
uint i,j;
for(i=xms;i>0;i++)
for(j=1320;j>0;j--);
}

void main()
{
h1=0;
h2=0;
h3=0;
