RE: Limitations of data line length/library/chipsets.
I’m looking into building an installation for my camp next year, with fairly long runs of LEDs (I think I’ll be doing 30/m for simplicity and costs sake), and I was wondering what sort of limitations there are on how far you can run a data wire/how many LED per strip can be controlled by FastLED (I want to run it all off a teensy, but might have to do something bigger or maybe synchronize multiple teensy’s). I know you have to run parallel power lines to prevent voltage drop. I am used to using ws2912B, but may switch chipsets if it makes more sense when doing longer runs of LEDs.
The reason I’d prefer longer runs of LEDs instead of breaking up strips is because 2nd or 3rd strips would have a significant physical distance from the source.
On the note of large scale LED installations, has anyone tried synchronizing multiple controllers before? What sort of methods do people employ to do this?
