    About 9 months ago, I was talking to an acquaintance that works at one of the well known chip manufacturers here in the USA about the chip shortages. They don't do CPUs, but they do many of the popular peripheral...

    Gotcha, I glossed over the fact that you were also going to use the Audio Adapter. I made one project that used the Audio Adapter and and was also running WS2812 LEDs and ran into the blocking issue. In my case I...

    Why not just use the same code you have shown for the Nano in the Teensy 4.0? It will also run faster. You also don't have to use the Octo2811 adapter to use the Octo2811 library. The adapter is basically just...

    The basic issue as you guessed is that the 3.3V drive is not high enough to fully turn on that MOSFET while the 5V was. If the MOSFET only partially turns on, it starts dropping a lot of voltage when you drive...

    I have seen that when there are signal integrity issues between the Teensy 4.1 and the audio adapter. It seems like even a momentary issue with MCLK can put it in a state giving that screeching noise that won't clear...
