STM32F4 Discovery Filter configration

Posted on June 30, 2016 at 20:53

Hello,

   can any one please provide me with CAN Filter configuration of  'FilterIdHigh', ''FilterIdLow', 'FilterMaskIdHigh', 'FilterMaskIdLow', 'BankNumber' of STM32F4 Discovery board. i want to receive any frame on CAN1 Receiver. i am using HAL Library.

I have configured my CAN Filter as follows.

/*CAN1 filter function*/

void CAN_filter_init(void)

{

CAN_FilterConfTypeDef  sFilterConfig;

 /*♯♯-2- Configure the CAN Filter ♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯*/

sFilterConfig.FilterNumber = 0;

    sFilterConfig.FilterMode = CAN_FILTERMODE_IDMASK;

    sFilterConfig.FilterScale = CAN_FILTERSCALE_32BIT;

    sFilterConfig.FilterIdHigh = 0xFFFF;;

    sFilterConfig.FilterIdLow = 0x0000;

    sFilterConfig.FilterMaskIdHigh = 0xFFFF;

    sFilterConfig.FilterMaskIdLow = 0x0000;

    sFilterConfig.FilterFIFOAssignment = CAN_FILTER_FIFO0;

    sFilterConfig.FilterActivation = ENABLE;

    sFilterConfig.BankNumber =14;

    HAL_CAN_ConfigFilter(&CanHandle, &sFilterConfig);

}

with this CAN configuration i am trying to receive frame on CAN1 using the following 

/*CAN1 Receving function */

void CAN_Rx(void)

{

      HAL_CAN_Receive(&CanHandle,CAN_FILTER_FIFO0, 10);

           datarx[0]=CanHandle.pRxMsg->StdId ;

          datarx[1] =CanHandle.pRxMsg->DLC;

           datarx[2]= CanHandle.pRxMsg->RTR   ;

           datarx[3]= CanHandle.pRxMsg->DLC   ;

           datarx[4]= CanHandle.pRxMsg->Data[0] ;

          datarx[5]= CanHandle.pRxMsg->Data[1];

}

please provide me with the correct can filter configuration.

Thanks in advance!
