    PaulStoffregen~
    On close inspection, it can be just under a bit time, at its shortest. And, sadly, I do not have control. What you see is comms between modules in an established product.
    But! What...

    I appreciate the help you're offering, and thanks, but I need to puzzle it out here. And it isn't worth it, as this is a very unusual situation--very non-standard. It's not a Teensy problem, but...

    Yes, thanks. In addition to the termination resistors across A and B, there's one pull-down on the A line and one pull-up on the B. As you know, an idle serial1--hardware serial--data line is high,...

    Thanks! And sorry for the confusion.
    I'm using serial1, hardware serial, on RS-485. (I'm not clever or daring enough to mess with USB.) And labels D+ and D- are sometimes used on the two...

    disabling UART break detection in T3.x

    Does anyone know if it's possible to disable break detection altogether in a T3.x UART? I'm trying to use a T3.x to communicate w/ an established '485 network. But it has terminating resistors in the...

    Thanks, all, for the sound advice. Not what I wanted to hear then, as I didn't want to leave C and switch to Arduino. But T3.x is well worth the effort, and C isn't really all that far away. I even...
  7. Teensy 2.0 and a change in crystal frequency

    Will USB still function with a clock frequency 7.84% low?
    I need to program a Teensy 2.0 to act as a node in a multipoint RS-485 network running at 230,400 baud. But it seems I can not get this baud...
  8. Can I change Teensy 2.0 oscillator frequency?

    I need 230.4 kbaud from my Teensy 2.0. So, I must replace the 16 MHz crystal with one at 14.7456 MHz. Only, what will that do to USB?
    Thanks very much.
