    Thank you! That was going to be my next question. This display is so darn fast that the FFT lines are barely visible. I was pondering ways to use page buffer arrays or something, and have them...

    Great. It seems I was kind of on the right track already, just didn't know about the Millis and Micros. Thanks.

    A new Teensy with built-in audio..?

    Lately I've been working with a Teensy 4.1 and the audio shield Rev D, and it got me thinking... Have the powers that be ever considered releasing a new version of Teensy with the SGTL5000 audio...

    Ok nevermind, I fixed it. I stared at the errors and re-read them repeatedly and poked around for like an hour until they finally sunk in, and I realized it was indeed a library conflict. Then I...

    Ok I'm lost with this one. It delves into library issues that I need words of wisdom for. There are many related posts in the forum that seem similar but not quite the same.

    I'm trying to use a...

    Hello. My apologies for this somewhat off-topic question: are the pins of the stacking headers the higher-quality solid square ones? If so, may I ask for vendors and part numbers? There are...
