    I've been following your progress. I am impressed. I am wondering how many universes you can push out of multiple outputs before any noticable slowdowns.

    Last year, I had 5 mini-trees, each with 50 pixels, all running from an Arduino Nano. FastLED split the outputs up among 5 outputs. I had that max485 convertor, and a cheap 485 serial adapter on the PC. It ran fine, but I've been trying to adapt and upgrade.

    I'd like to start with a program like this, but split each universe into 3 outputs(50 each for my mini trees). My other option is to daisy-chain the trees in groups of 3.

    Please share your completed code.

    A fellow DiYc member pointed out that the wemos d1 is a better and cheaper option than the nodemcu . I switched and have been impressed with it's smaller size and performance so far .
    If you plan to go wireless I recommend them also .
    Your tree setup would be quite straight forward with 300 pixels over 2 universes using only 2 outputs .

    The 1st code in post #7 would be sufficient for your trees .

    Thanks for your reply.
    I've got a few D1 mini's. They are neat.
    Also have the UNO version, and a bunch of the ESP01's.

    I just ordered a bunch of the NodeMCU's from a guy on eBay. They were part of a PS4 firmware hack that got abandoned. I ordered 8 for less than $4 each, free shipping. Considering getting some more.

    That is a great buy . Have you programmed and put the D1 or 01's to use ?
    With the use of Forkineye's firmware and examples , you can't go wrong .
    Absolutely fun to experiment with .

    I have a D1 mini and an UNO sized(D1 R2?) In enclosures with small power supplies.
    I got a batch of 01's with the weird flash chip, so they are gonna end up in my home-automation projects.

    Time for an update

    I still had issues with the channel numbers so I decided to do this:
    Have the code in the sketch like this
    new channel code.png

    Then the universe config like this:
    new channel code 2.png

    And xlights like this:
    lights universes.png

    and I tested with all 4 sets of LED strips and the star and it worked perfect, save for some power injection.

    I did notice it was a little laggy on some on the effects, so just for the fun of it I used my D1 mini and if fixed the lag.
    This little board performs better than the Node MCU (as it was mentioned above) I think especially for the longer runs of lights.

    I corrected post #20 lack of accounting for unused pixels .
