WS2813 and octo28 adaptor?

Hello, WS2813 seems pretty interesting, but since it seems to require 2 data lines, it won’t be usable with the octo28 adaptor, right?

Any feedback on that here?

Regards

It should be compatible- the extra data input is just for redundancy, so you can connect the octo28 data output to the D1 input on the WS2813 strip, and it will work as intended.

Optionally, you could also connect a single octo28 data output to both data inputs on the WS2813 strip- that way, if the first LED on the strip fails, then the data will automatically be picked up by second LED on the strip. This is a little goofy since it shifts your whole pattern over by 1 LED, but could be better than having the strip go out.

Make sure you have a recent version of the library, and use WS2813_800kHz as the LED type. This was contributed several months ago. I have not personally tested it, but I did buy a couple reels of WS2813s that have been collecting dust (in case anyone reports problems). https://github.com/PaulStoffregen/OctoWS2811/commit/e0f4e474f1aa1a14e10dbfc90d109134ca21b1a7

@Matt_Mets it shouldn’t shift things by one led - the WS2813 chip knows which pin the data is coming in on, and when the data comes in on the ‘backup pin’ and no data comes in on the main pin, then it knows that it needs to skip a single led’s worth of data.
