AWR6843AOP: AWR6843AOP

Steven Yeh

Part Number: AWR6843AOP

Tool/software:

My radar SoC is the AWR6843AOP, which supports the CAN-FD protocol. My question is whether the AWR6843AOP can directly connect to a CAN-HS bus. I understand that CAN-FD and CAN-HS have different formats. Can they communicate with each other, and if so, how? What modification I should do to make it possible? Any valuable information is welcome. Thanks.

    Hey Steven,

    Thanks for reaching out regarding CAN usage on AWR6843AOP. I would recommend looking over the CAN Integration User Guide and Example in the Radar Toolbox which is a great starting point for CAN users. As for communicating between the two formats, the CAN-FD format supports classic CAN up to 1 Mbps by setting the FDF bit to 0 within the control field of the message. The FDF bit for the Rx buffer or FIFO also determines whether or not classic CAN is received or not - FDF = 0 (classic), FDF = 1 (CAN_FD).

    The CAN Integration Example supports the classic frame format by setting the global frameType variable to CANFD_MCANFrameType_CLASSIC and the fdMode parameter to 0 in the MCANAppInitParams function.

    Hopefully this helps, but let me know if you have any other questions.

    Regards,

    Kristien
