Can Example Problem with CubeMX

[voyvoda .]

Hello,

       I am trying to implement a canbus example. I was used can example with no problem in the CubeMX Version 4.24. Now, I have updated the CubeMX to version 4.25.1. Can exampel is not working now. There are some changes between version. Can someone explain me Why ?

       In the newer version there is no 

pTxMsg

and 

pRxMsg

buffers. How can I send and receive data via newer version of the CubeMx.

      Is there an example for the newer version of the CubeMx ?

NEW

typedef struct __CAN_HandleTypeDef

{ CAN_TypeDef *Instance; /*!< Register base address */

CAN_InitTypeDef Init; /*!< CAN required parameters */

__IO HAL_CAN_StateTypeDef State; /*!< CAN communication state */

__IO uint32_t ErrorCode; /*!< CAN Error code.

This parameter can be a value of @ref CAN_Error_Code */

} CAN_HandleTypeDef;

OLD

typedef struct

{ CAN_TypeDef *Instance; /*!< Register base address */

CAN_InitTypeDef Init; /*!< CAN required parameters */

CanTxMsgTypeDef* pTxMsg; /*!< Pointer to transmit structure */

CanRxMsgTypeDef* pRxMsg; /*!< Pointer to reception structure for RX FIFO0 msg */

CanRxMsgTypeDef* pRx1Msg; /*!< Pointer to reception structure for RX FIFO1 msg */

__IO HAL_CAN_StateTypeDef State; /*!< CAN communication state */

HAL_LockTypeDef Lock; /*!< CAN locking object */

__IO uint32_t ErrorCode; /*!< CAN Error code */

}CAN_HandleTypeDef;

Hi

kavak.engin

,

Thanks for your feedback.

Effectively the CAN Driver has changed compared to the lastest version, you can find the new example in STM32CubeF4 1.0 available on ST Web page.

Please feel free to contact me for further details.

Hello,

I am facing the similar issue with STMCubeMX 5.3.0 and firmware version 1.24.2 . There are no pTxMsg and pRxMsg buffers available when I am generating a code through cube. I am using STM32F407 Discovery board. Kindly help.

typedef struct __CAN_HandleTypeDef

{

CAN_TypeDef *Instance; /*!< Register base address */

CAN_InitTypeDef Init; /*!< CAN required parameters */

__IO HAL_CAN_StateTypeDef State; /*!< CAN communication state */

__IO uint32_t ErrorCode; /*!< CAN Error code.
