Process Outgoing Messages

By using a breakpoint on the CAN0OUT register it is possible to invoke debug functions. The debug function might check the CAN message object and may send a reply to the CAN message or invoke a signal function that sends a delayed reply. The following example shows the usage:

FUNC void CANmessage (void)  {
  switch (CAN0OUT)  {
    case 1: printf ("\nSend Message (11-bit ID=%04X)", CAN0ID);     break;
    case 2: printf ("\nSend Message (29-bit ID=%08X)", CAN0ID);     break;
    case 3: printf ("\nRequest Message (11-bit ID=%04X)", CAN0ID);  return;
    case 4: printf ("\nRequest Message (29-bit ID=%08X)", CAN0ID);  return;
  }

  printf ("\nMessage Length %d, Data: ", CAN0L);
  printf ("%02X %02X %02X %02X ",   CAN0B0, CAN0B1, CAN0B2, CAN0B3);
  printf ("%02X %02X %02X %02X \n", CAN0B4, CAN0B5, CAN0B6, CAN0B7);
}

>BS WRITE CAN0OUT, 1, "CANmessage ()"  // call CANmessage debug function with outgoing messages

Note

All CAN messages can be review also in the CAN communication dialog page.
