    I mounted my Teensy 3.6 in a breadboard now, and I'm getting the same problem. Both with my own code and with the FastLED example demoreel100

    I can do that tomorrow (time for me to go to bed at the moment).
    Both the Teensy and my LED strips are connected to the same PSU though, so they should have common ground
  3. My LEDs work fine with Teensy3.2, but has the wrong colors and flicker with Teensy3.6

    Hello.
    I am trying to run my LED programs on a Teensy 3.6. They have usually been working fine with Teensy 3.2, but on the Teensy 3.6 the colors are wrong, and the LEDs flicker.
    I have an octo...

    What I want want to do is 16 strips with 150 LEDs each.
    Would it be better then to use 8 outputs, and chain two and two strips you think?
    My main reason for not wanting to do that is that I have to...

    What I'm thinking about is using FastLEDs functionality for multiple outputs, and then just wiring the output pins of the Teensy to input pins on the octo boards.
    That should work right? Unless...
  7. Is a Teensy 3.6 with two octobords possible?

    I would like to to have more than 8 parallel LEDstrip outputs, and I'm wondering if it's possible to connect two octo boards to one Teensy 3.6?

  14. Program stops when it encounters FastLED.show()
