    Any hint on how to do that?

    I tried it again on the two 3.0s (I on'y have one 3.1 available) and it works at 4M but with lots of errors.
    Sorry I must have something else screwy before. Of like I...

    Ok write(buf, len) and 4MHz on the 3.1 should be just fast enough then.
    Thank you for the very thorough response!

    Haha yes I mean 1500000 of course.

    But the basic question still remains, is 115200 really the fastest it will go? Rates higher than that don't really transfer any faster?

    Same code but
    #define rate 115200*10
    was
    #define rate 15000000

    At that point I was no longer getting anything in the serial window and since I don't have a scope that fast I couldn't see what...

    Thanks so much Paul. Yes I'm using two 3.0.

    I didn't realized micros() saw so slow. That explains some other timing problem I've been having.

    I can only afford about 10us so I guess I'll just...

    Yes the code works fine at 11520 but I was hoping it could be faster. As you were saying in this post, the UART should be able to go over 115200.

    Thanks y'all.


    You mean the digital writes and serial? They are outside the speed test.


    I haven't seen any posts on how to implement DMA in a general sense. Any ideas?

    UART speed weirdness

    I'm trying to send bytes between two Teensy 3s but can't seem to transfer them any faster by raising the baud past 115200.

    byte j,RX,g;
