程序如下

typedef unsigned int  u16;
typedef unsigned char u8;

#define DATA P0
sbit rs = P2^1;
sbit rw = P1^5;
sbit en = P1^6;
void delay(u16 num)
{
        u16 x,y;
        for (x=num; x>0; x--)
                for(y=110; y>0; y--);
}
void write_cmd (u8 cmd)
{
        rs = 0;
        rw = 0;
        DATA = cmd;
        delay(5);
        en = 1;
        delay(5);
        en = 0;
}
void write_data (u8 dat)
{
        rs = 1;
        rw = 0;
        DATA = dat;
        delay(5);
        en = 1;
        delay(5);
        en = 0;
}
void lcd_init (void)
{
        write_cmd(0x01);
        write_cmd(0x06);
        write_cmd(0x0f);
        write_cmd(0x38);
        write_cmd(0x01);
}

int main (void)
{
        rw = 0;
        rs = 0;
        en = 0;
        lcd_init();
        write_cmd(0xc0);
