Life isn't about finding yourself, life is about creating yourself.

我看了一下git里的文件，这个驱动是不是只支持f1。不如里面的这个机构体的几种类型的名字，基本都是F1的叫法，F4里面不一样。（我也不确定是不是我这边文件的问题）

```
struct stm32_drv_can
{
    CAN_HandleTypeDef CanHandle;
    CAN_TxHeaderTypeDef TxMessage;
    CAN_RxHeaderTypeDef RxMessage;
    CAN_RxHeaderTypeDef Rx1Message;
    CAN_FilterTypeDef FilterConfig;
};
```

比如CanTxMsgTypeDef这个定义
stm32f1xx_hal_can.h里面是这样的

```
typedef struct
{
  uint32_t StdId;    /*!< Specifies the standard identifier.
                          This parameter must be a number between Min_Data = 0 and Max_Data = 0x7FF */

uint32_t ExtId;    /*!< Specifies the extended identifier.
                          This parameter must be a number between Min_Data = 0 and Max_Data = 0x1FFFFFFF */

uint32_t IDE;      /*!< Specifies the type of identifier for the message that will be transmitted.
                          This parameter can be a value of @ref CAN_Identifier_Type */

uint32_t RTR;      /*!< Specifies the type of frame for the message that will be transmitted.
                          This parameter can be a value of @ref CAN_remote_transmission_request */

uint32_t DLC;      /*!< Specifies the length of the frame that will be transmitted.
                          This parameter must be a number between Min_Data = 0 and Max_Data = 8 */

uint8_t Data[8];   /*!< Contains the data to be transmitted.
                          This parameter must be a number between Min_Data = 0 and Max_Data = 0xFF */

}CanTxMsgTypeDef;
```

而f4下面类似的定义是这样的，名字不一样

```
typedef struct
{
  uint32_t StdId;    /*!< Specifies the standard identifier.
                          This parameter must be a number between Min_Data = 0 and Max_Data = 0x7FF. */

uint32_t ExtId;    /*!< Specifies the extended identifier.
                          This parameter must be a number between Min_Data = 0 and Max_Data = 0x1FFFFFFF. */

uint32_t IDE;      /*!< Specifies the type of identifier for the message that will be transmitted.
                          This parameter can be a value of @ref CAN_identifier_type */

uint32_t RTR;      /*!< Specifies the type of frame for the message that will be transmitted.
                          This parameter can be a value of @ref CAN_remote_transmission_request */

uint32_t DLC;      /*!< Specifies the length of the frame that will be transmitted.
                          This parameter must be a number between Min_Data = 0 and Max_Data = 8. */

FunctionalState TransmitGlobalTime; /*!< Specifies whether the timestamp counter value captured on start
                          of frame transmission, is sent in DATA6 and DATA7 replacing pData[6] and pData[7].
                          @note: Time Triggered Communication Mode must be enabled.
                          @note: DLC must be programmed as 8 bytes, in order these 2 bytes are sent.
                          This parameter can be set to ENABLE or DISABLE. */

} CAN_TxHeaderTypeDef;
```

这样导致编译时候有大量的报错
