我知道RTT支持F7，不过它的CAN驱动好像不支持，只支持F1和F4系列？

```
#include "drv_can.h"

#ifdef RT_USING_CAN

#if defined (SOC_SERIES_STM32F1)
static const struct stm_baud_rate_tab can_baud_rate_tab[] =
{
    {CAN1MBaud  , (CAN_SJW_2TQ | 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_3TQ | 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_3TQ | 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)}
};
#elif defined (SOC_SERIES_STM32F4)
static const struct stm_baud_rate_tab can_baud_rate_tab[] =
