写一个51单片机lcd1602显示iloveyou的代码

下面是51单片机LCD1602显示iloveyou的代码：

#include <reg51.h>

#define LCD_DATA P0
sbit RS = P2^0;
sbit RW = P2^1;
sbit EN = P2^2;

void delay(unsigned int i)
{
while(i--);
}

void lcd_write_cmd(unsigned char cmd)
{
RS = 0;
RW = 0;
EN = 1;
LCD_DATA = cmd;
delay(100);
EN = 0;
}

void lcd_write_data(unsigned char dat)
{
RS = 1;
RW = 0;
EN = 1;
LCD_DATA = dat;
delay(100);
EN = 0;
}

void lcd_init()
{
lcd_write_cmd(0x38);
lcd_write_cmd(0x0c);
lcd_write_cmd(0x06);
lcd_write_cmd(0x01);
}

void main()
{
