嵌入式粤嵌开发板爱心代码

以下是一个简单的嵌入式粤嵌开发板爱心代码的示例：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "stc12c5a60s2.h"

#define FOSC 11059200L
#define BAUD 9600

#define LED P1

void delay(unsigned int xms)
{
    unsigned int i, j;
    for (i = xms; i > 0; i--)
        for (j = 112; j > 0; j--);
}

void uart_init()
{
    SCON = 0x50;
    TMOD &= 0x0F;
    TMOD |= 0x20;
    TH1 = TL1 = FOSC / 12 / BAUD;
    TR1 = 1;
}

void uart_send(char dat)
{
    SBUF = dat;
    while (!TI);
    TI = 0;
}

void main()
{
    uart_init();
    LED = 0xff;
    while (1)
    {
        LED = 0x81;
        delay(500);
        LED = 0x42;
        delay(500);
        LED = 0x24;
        delay(500);
        LED = 0x18;
        delay(500);
        uart_send('I');
        uart_send(' ');
        uart_send('L');
        uart_send('O');
        uart_send('V');
        uart_send('E');
        uart_send(' ');
        uart_send('Y');
        uart_send('O');
        uart_send('U');
        uart_send('!');
    }
}

该代码使用了STC12C5A60S2芯片进行开发，实现了在一组LED上显示一个闪烁的爱心，并使用串口输出"I LOVE YOU!"的信息。
