Part Number: AWR2944

Tool/software:

1、Does the 2944 support CAN bus and data transmission/reception on the bus?

2、Is there any CAN bus code demo for the 2944?Does 2944 support can function based on the TDMDemo?

    Hello,

    Yes the 2944 supports CAN transmission.

    Yes there is demo code present at the following path in the Radar Toolbox. It is by default a DDM demo but should be able to be built in TDM mode.

    It helps a lot!

    I have another question,If I wanna receieve and send can data at the same time,Which solution is more recommended?Is one can instance used by two core of ARM allowed?

    1、use dual core to do it,such as core 0 of r5f to receieve and core 1 of r5f  to send data out?

    2、use single core to do it,core 0 to send and receieve?

    Hello,

    I would recommend starting with just using 1 core to save complexity. Also because by default I believe the r1 core is in lock-step mode to do functional safety. This would take more work to figure out how to run the device in split-core mode (essentially having two cores available for use). So, yes start with a single core for your application.

    Best,
