  1. Closed: Re: Data Transfer over long twisted pair cable

    Hello,

    I would like to relate to your opinions:

    1) It is possible (in real environment) to achieve bit rate 12 Mbit/s on "CAN FD". I agree that it is not possible for such long distance.

    Closed: Re: instruction set translator

    Hello,
    yes you are right :). The assumption to emulate more complicated CPU on smaller and simpler one is bad choice. But you can see how things are done in such examples.
