Posted on June 30, 2016 at 20:53Hello,
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!
