Hi,

See the snapshot below. The ISR inside the pragma segment in CAN1.c source file must be available (out of comment; not in red)

You can use the following code inside the ISR to service the CANRx interrupt:

ISR(CANRxISR)

{

   unsigned char length, index;

    unsigned char rxdata[8];

    length = (CAN0RXDLR & 0x0F);

      for (index=0; index<length; index++)

          rxdata[index] = *(&CAN0RXDSR0 + index); /* Get received data */

    CAN0RFLG = 0x01;   /* Clear RXF */

}

Hopefully the info helps.

Regards.
