  • Good day, ALFA!

    How's it going for you? Have you made any progress on this? I found an app note that might be useful to you. You may also refer to this thread to get some ideas regarding stuff error. For the BUS heavy error, the only information I found is this error can be caused by a missing termination resistance.

    I hope that can help you a bit. Looking forward for more responders to comment on this also.
