    else

        return -1;
    }

void led1_thread_entry(void* parameter)
{
    while(1)
    {
        LED_TOG;
        rt_thread_delay(500);
    }
}

但编译报错，主要有以下4点：
implicit declaration of function 'rt_sem_init' [-Wimplicit-function-declaration]
     rt_sem_init(&heap_sem, "heap", 1, RT_IPC_FLAG_FIFO);
	 implicit declaration of function 'rt_sem_take' [-Wimplicit-function-declaration]
     rt_sem_take(&heap_sem, RT_WAITING_FOREVER);
	 implicit declaration of function 'rt_sem_release' [-Wimplicit-function-declaration]
             rt_sem_release(&heap_sem);
			 storage size of 'heap_sem' isn't known
 static struct rt_semaphore heap_sem;
