```c
int rt_application_init(void)
{
	rt_event_init(&main_event, "main_event", RT_IPC_FLAG_PRIO);
	usart1_thread = rt_thread_create(
												"uart1",
												usart1_thread_entry,
												RT_NULL,
												512,
												24,
												10);

main_thread = rt_thread_create(
													"main",
													main_thread_entry,
													RT_NULL,
													512,
													24,
													10);
	if(main_thread != RT_NULL)
	{
		rt_thread_startup(main_thread);
	}
}

static void main_thread_entry(void* parameter)
{
	rt_uint32_t recved;

if (usart1_thread != RT_NULL)
	{
		rt_thread_startup(usart1_thread);
	}
	while(1)
	{
		rt_event_recv(&main_event,
						(EVENT1|EVENT2),
						RT_EVENT_FLAG_OR|RT_EVENT_FLAG_CLEAR,
						RT_WAITING_FOREVER,
						&recved);
		if (recved == (USART1_EVENT)) {
			
			rt_kprintf("t1 thread suspend");
			rt_thread_suspend(t1_thread);
								
			t2_thread = rt_thread_create(
										"t2",
										t2_thread_entry,
										RT_NULL,
										512,
										25,
										10);
			rt_thread_startup(t2_thread);

}
		 else if (recved == (EVENT2)) {
			 
			rt_kprintf("t2_thread  event send");

rt_thread_resume(t1_thread);

}
		rt_thread_delay(10);
	}
}
void t1_thread_entry(void* parameter)
{
	rt_thread_resume(main_thread);
	rt_event_send(&main_event, EVENT1);
}
void t2_thread_entry(void* parameter)
{
	rt_kprintf("t2_thread enter");
	rt_event_send(&main_event, EVENT2);
}
```
