    Hi John,

    F28377D has CAN modules that is compliant with ISO11898-1 (Bosch CAN Protocol 2.0 A and B).  TI provides drivers and example codes for carrying out communications through CAN in C2000Ware but nothing specific to the heavy-duty vehicle SAE J1939 standard.  You probably need a higher level protocol to translate the messages/IDs to support the SAE J1939 standard.  When the CANTX/RX pins are connected to an external transceiver, the CAN module in the F28377D can communicate to any node in the CAN bus.

    Not sure if i have addressed your query, if not let me know so i can provide more details.

    Best regards,

    Joseph

    Hi John,

    In case it is helpful for you, we do have a list of third-party developers who provide CAN stack solutions (including SAE J1939):

    You can find details under the Third Party Software Stacks section in the following page:
    https://www.ti.com/microcontrollers/c2000-real-time-control-mcus/design-development.html#software

    If Simma has not provided a port to your specific device & you are interested, you can reach out to them as they are generally quite responsive.


    Thank you,
    Brett
