Currently running Vixen with my Teensy/Octo however I'm interested in trying Xlights. Lots of research and searching has led me to this working sketch;
However, during my testing the LEDs flicker on/off really fast. I get the right colours/effects so I'm fairly confident everything set up right in Xlights.
Power injection not an issue as only using 5ox5v string.

I'm not confident in changing the code as I don't understand what it all means.

Any thoughts?
