#include <rtthread.h>
#include <rtdevice.h>

#define LED_ON  1
#define LED_OFF 0

ALIGN(RT_ALIGN_SIZE)
static rt_uint8_t led_stack[128];
 /* 线程的TCB控制块 */
static struct rt_thread led_thread;

static void rt_led_ctrl(rt_uint8_t ledstatus)
{
	rt_pin_write(LED_0_PIN, ledstatus);
}

void rt_hw_led_init(void)
{
	rt_pin_mode(LED_0_PIN, PIN_MODE_OUTPUT);
	
	rt_led_ctrl(LED_OFF);	
}

static void led_thread_entry(void *parameter)
{
	rt_hw_led_init();
	
	while(1)
	{
		rt_led_ctrl(LED_ON);
		rt_thread_delay(RT_TICK_PER_SECOND/2);
		
		rt_led_ctrl(LED_OFF);
		rt_thread_delay(RT_TICK_PER_SECOND/2);
	}
}

int rt_led_init(void)
{
    rt_err_t res;
	
	res = rt_thread_init(&led_thread,
						"led",
						led_thread_entry,
						RT_NULL,
						(rt_uint8_t *)&led_stack[0],
						sizeof(led_stack),
						10,
						10);
	if(RT_EOK == res)
		res = rt_thread_startup(&led_thread); 
	else
		return -1;
	
	return 0;
}

#if defined (RT_SAMPLES_AUTORUN) && defined(RT_USING_COMPONENTS_INIT)
    INIT_APP_EXPORT(rt_led_init);
#endif

这就是LED的代码了 没啥东西
