10 我是STM32F103 CAN通信只发送一次就卡住了，有时候就正常

```c
while(1)
{
		CanTxData.data[0] = 0x01;
		CanTxData.data[1] = 0x02;
		CanTxData.data[2] = 0x03;
		CanTxData.data[3] = 0x04;
		CanTxData.data[4] = 0x05;
		CanTxData.data[5] = 0x06;
		CanTxData.data[6] = 0x07;
		CanTxData.data[7] = 0x08;
	    rt_device_write(can_seial, 0, &CanTxData, 8);
		rt_kprintf("send OK!!\r\n");  
		rt_thread_delay(100);
	}
```
相关问题，比如波特率我也改了！！！！！100k
```c
	#if defined (SOC_SERIES_STM32F1)/* APB1 36MHz(max) */
static const struct stm32_baud_rate_tab can_baud_rate_tab[] =
{
    {CAN1MBaud, (CAN_SJW_1TQ | CAN_BS1_8TQ  | CAN_BS2_3TQ | 3)},
    {CAN800kBaud, (CAN_SJW_2TQ | CAN_BS1_5TQ  | CAN_BS2_3TQ | 5)},
    {CAN500kBaud, (CAN_SJW_2TQ | CAN_BS1_8TQ  | CAN_BS2_2TQ | 6)},
    {CAN250kBaud, (CAN_SJW_2TQ | CAN_BS1_8TQ  | CAN_BS2_3TQ | 12)},
    {CAN125kBaud, (CAN_SJW_2TQ | CAN_BS1_8TQ  | CAN_BS2_3TQ | 24)},
    {CAN100kBaud, (CAN_SJW_2TQ | CAN_BS1_8TQ  | CAN_BS2_2TQ | 30)},
    {CAN50kBaud, (CAN_SJW_2TQ | CAN_BS1_8TQ  | CAN_BS2_3TQ | 60)},
    {CAN20kBaud, (CAN_SJW_2TQ | CAN_BS1_8TQ  | CAN_BS2_3TQ | 150)},
    {CAN10kBaud, (CAN_SJW_2TQ | CAN_BS1_8TQ  | CAN_BS2_3TQ | 300)}
};
```
