How to Enable CAN Receiver Interrupt in CAN PAL Example code

[Dileep1441]

Hi,

I'm using CAN PAL Example code in S32K144 EVB with S32DS.ARM.2018.R1 IDE.

I want to enable the CAN Receiver interrupt in CAN PAL Example code, i don't want to block my code with while loop like below

CAN_ConfigRxBuff(INST_CAN_PAL1, RX_MAILBOX, &buffCfg, Rx_Id);
/* Start receiving data in RX_MAILBOX. */
CAN_Receive(INST_CAN_PAL1, RX_MAILBOX, &recvMsg);

while(1)
{
         /* Wait until the previous FlexCAN receive is completed */
         if(CAN_GetTransferStatus(INST_CAN_PAL1, RX_MAILBOX) == STATUS_SUCCESS)
         {
             CAN_Rx_test_ID = recvMsg.id;
             CAN_Receive(INST_CAN_PAL1, RX_MAILBOX, &recvMsg);

         }
}

Here my requirement is when ever the CAN Message is received on CAN Bus, CAN Receiver Interrupt need to Trigger so that without blocking of my code with while loop, i can handle the received CAN Messages

Hope you understand my requirement, please share your suggestion or code with required config settings to fulfill my requirement.

Thanks in Advance.

Hi Dileep1441,

Please refer to the examples in S32K1xx SDK FlexCAN sample projects to demonstrate its basic and advanced features
You will find the CAN_TX_RX_Callback in ...\S32K144_CAN_PAL_SamplePrj_Basic_TxRx_ID_FiltersConfig_SDKRTM3P0\Sources\can_api.c

Hope it helps.

Best Regards,
Robin
