好的 谢谢

```c
void can_recv_thread(void* parameter)
{
	recv_sem = rt_sem_create("recvsem", 0, RT_IPC_FLAG_FIFO);
	tran_sem = rt_sem_create("transem", 0, RT_IPC_FLAG_FIFO);

can_slave_init();

test_slave();

/* Infinite loop*/
  while(1)
  {
		rt_sem_take(recv_sem, RT_WAITING_FOREVER);

{
			uint32_t next;
			Message *pmsg;
			
			next = rx_read;
			pmsg = &rx_msg_buf[next];

/* Disable the Interrupt sources */
    	TIM5->DIER &= (uint16_t)~TIM_IT_CC1;
			canDispatch(&TestSlave_Data, pmsg);
			/* Enable the Interrupt sources */
    	TIM5->DIER |= TIM_IT_CC1;

next++;
			if(next >= RX_BUF_LEN) next = 0;
			rx_read = next;
		}
  }
}

void can_send_thread(void *parameter)
{
	while(1)
	{
		rt_sem_take(tran_sem, RT_WAITING_FOREVER);

{
			uint32_t next;
			uint8_t  mailbox_no;
			CanTxMsg *ptx_msg;
			
			next = tx_read;
			ptx_msg = &tx_msg_buf[next];

mailbox_no = CAN_Transmit(CAN1, ptx_msg);
			if(mailbox_no != CAN_NO_MB)
			{
				next++;
				if(next >= TX_BUF_LEN) next = 0;
				tx_read = next;			
			}
			else
			{
				rt_sem_release(tran_sem);
			} 
		}
	}		
}
```
