    This looks very interesting and am looking forward to the details!

    BTW, the video you included is unavailable as it is private.

    This might be a long shot, but it sounds like you might be using enough memory that you could have a variable (a large array) crossing the SRAM_L and SRAM_U boundary, which under some access...
  4. Halloween 2020 Light Show, with 3000 leds, run by a Teensy 3.2 @ 60fps

    I've been using a Teensy 3.2 with the OctoWS2811 board and library for the past few years to run much of my Halloween and Christmas light shows. This year, I reworked the code on the Teensy 3.2 to...

    I found that adding "__attribute__((aligned(2048)))" to the megaBuffer declaration did a good enough job of coercing the linker to keeping from placing it across the SRAM_L / SRAM_U boundary. With...

    I think I've been able to confirm the issue is related to the SRAM_L / SRAM_U boundary. In the sym file, it showed the megaBuffer was being placed just before the boundary and it's length would go...

    Can you post the code you're running on the Teensy 3? Your video looks similar to an issue I'm seeing with my ws2811 setup.

    defragster,
    I did some testing using your code. The only modification I made was to setup() where I commented out Serial lines after qBlink and just set rCnt to 12408. I also switch to n =...

    Thanks for the reply defragster!

    I gave your suggestion a try and still encountered more or less the same result, but it did get me to find a simpler repo and it might have provided, what I think...
  11. Teensy 3.2, OctoWS2811, and large Serial.readBytes hang

    I'm using a Teensy 3.2 with the OctoWS2811 Adaptor, connected via USB Serial to a Raspberry Pi 4 running Falcon Player v3.3 (Raspbian based) to control 2378 WS2813 LEDs being updated at 25ms...
