Looks from the picture like its regular WS2801 (which we support), but maybe alternating pixels are RGB, then W, then RGB, then W.

In that case, programming it would be a bit odd at first, but totally doable. Your code would have to account for the “odd pixels are RGB, even pixels are W” setup.

Oops- and to answer your question directly, no I do not have experience doing this with these strips.

Thanks for the answer @Mark_Kriegsman Is the divide of even an odd pixels with an function of fast led realisable? So that I can learn and use the exampels shown here. Or have I to recreate everything with this special adressing? Thanks for your help

Well, to just program the RGB leds, multiply every index by 2.

Other than that, it’s all your code.

The library doesn’t have high level RGBW support at all really, although it can drive those pixels (I bet).

I’m curious, how are RGBW strips wired? For example, with a WS2801 controller chip, would every forth chip control three individual white LEDs with it’s R,G,B outputs? Maybe like: https://drive.google.com/file/d/0B1DBHDKW1M8ua3JwZEhqZWJGSmc/view

Seems a bit complicated for wiring and coding, even more so if the LPD8806 chip was used. Or are RGBW strips using something completely different?

I’m just speculating that it might be
RGB WWW RGB WWW RGB WWW
or maybe
RGB W-- RGB W-- RGB W–

Ah that would make much more sense, both for simplicity of wiring and coding. My brain was trying not to waste precious controller chip resources. :stuck_out_tongue:

Yes they are rgb www rgb www… I’m will get them with apa 102 included in warm white led and rgb led. This will be awesome I think

I’d be interested in trying out some of those! I’ll see if I can find a way to get some myself.

Yes, yes. Please share if you find APA102 RBGW strips. I’m interested too.
Also, I just sent a message to Ray wu asking if he has thought about making an APA102 RGBW strip.

I wrote with Lauren (lauren@szlcoe.com) from shenzen LED color. in their poducts they offer are warm white APA 102 LEDs and APA102 RGB LEDs so I thought they could mix it and this is possible. You can’t find the stripe in their offer on the website ( http://www.szledcolor.com/product.asp?sid=188&i=1&j=14 ) but if you make an inquiry you will get it too :slight_smile:

Oooh interesting. Thank you Lars.

http://www.sfleds.com, it’s a factory and produce large quantity apa102 RGBW strips, very good quality and price.
