    Thanks for your reply! You're very right. I think for this type of application the SPI chipsets are absolutely the way to go. In this case, I don't really need high precision, so I was hoping to eek...

    Thanks for the reply. I went back into the sketch to add Octo and I found some interesting when I removed the delay normally necessary to write LEDs on the 4.0. It's very finicky, but I might be able...

    Thanks for taking a look I'll add the code with tags. I tried every pin for the ADC using adc1(A0-A7), I just moved it to A2 to more easily test different audio library configs.

    Teensy 4.0 ADC FFT - Current State

    Hello! I have been working through a number of microphones to get FFT working from the Teensy 4.0. All of the code worked great with the i2s microphone, but then I found out it spoiled the timing for...

    That makes sense. I'm just a little bit confused that it seems to break output even when FastLED is only writing one light. It break output even if it only writes to that light once every second,...

    More great information! Thank you. I thought i2s was a higher level system, but it looks like little i2s BOBs may be just as good as the analog one I have.
