Posted on June 02, 2018 at 06:35Set can model Init setting in STM32CubeBx,and generate Code in keil5 project ,and then set Filter of can1 and can2 ,two of can 's transmation is OK,but receive is not;
Code as this:
CAN_FilterConfTypeDef FilterConfig;
CanTxMsgTypeDef TxMsg;
CanRxMsgTypeDef RxMsg;
FilterConfig.FilterIdHigh = 0;
FilterConfig.FilterIdLow = 0;
FilterConfig.FilterMaskIdHigh = 0;
FilterConfig.FilterMode =0;
FilterConfig.FilterNumber=0;
FilterConfig.FilterScale= CAN_FILTERSCALE_32BIT;
FilterConfig.FilterFIFOAssignment= CAN_FILTER_FIFO0;
FilterConfig.BankNumber= 0U;
FilterConfig.FilterActivation= ENABLE;
HAL_CAN_ConfigFilter(&hcan1, &FilterConfig);
FilterConfig.BankNumber= 14U;
FilterConfig.FilterFIFOAssignment= CAN_FILTER_FIFO1;
HAL_CAN_ConfigFilter(&hcan2, &FilterConfig);
for(;i<8;i++)
TxMsg.Data[i] = i+1;
TxMsg.DLC = 8;
TxMsg.IDE = CAN_ID_EXT;
TxMsg.ExtId = 0x02222222;
TxMsg.RTR= CAN_RTR_DATA;
hcan2.pTxMsg = &TxMsg;
hcan2.pRx1Msg = &RxMsg;
void main
{
HAL_CAN_Receive(&hcan1, CAN_FIFO0,10);
HAL_CAN_Receive(&hcan2, CAN_FIFO1,10);
}
register RF0R.FMP1 and RF1R.FMP1 when receive would be more than 0
and why?
thanks !!!
