CAN Simulation for the 8051 - Incomming messages

Stewart Hill

Hi I've been trying to simulate receiving an incomming message from the CAN bus. I have followed the application notes AP147 and 167, and I have viewed discussion topics on this subject.

I have included an ini file (project options > debug) with the following code to simulate a CAN signal:

 CAN0ID = 0x196;     //CANID
 CAN0L  = 1; //Data length
 CAN0B0 = 0x01; //Data
 CAN0IN = 1;    //11bit Identifier

But I get errors messages after each line.

*** error 34, line 9 : undefined identifier

does anyone have any suggestions?

    The Infineon C515C has just one CAN channel. The debug command DIR VTREG shows the available registers:

            :
       CANID:  ulong, value = 0x00000000
        CANL:  uchar, value = 0x00
       CANB0:  uchar, value = 0x00
       CANB1:  uchar, value = 0x00
       CANB2:  uchar, value = 0x00
       CANB3:  uchar, value = 0x00
       CANB4:  uchar, value = 0x00
       CANB5:  uchar, value = 0x00
       CANB6:  uchar, value = 0x00
       CANB7:  uchar, value = 0x00
       CANIN:  uchar, value = 0x00
      CANOUT:  uchar, value = 0x00

    The CAN peripheral registers have just the name CANID, not CAN0ID as it is the case with devices where multiple CAN channels exist.
