Hi I am new here and delving into the ability to use Arduino as a master SPI controller for some RGB LED Strip. They use UCS2903, and this chipset doesn’t seem to be supported in the library.
Ideally I would like to “hack” some existing code from within the library to get this chipset to work? Looking for any pointers, experience, or help to get this working.
Even if someone could point me in the right direction to find information it would be greatly appreciated. 
I have attached the datasheet of the chip, however its in chinese, so I have been using Google translate to read it.
Thanks in advance

It doesn’t use SPI - the protocol and timing look identical to the ws2811 chipset so you can probably just use that
Do you know of any good resources that you could point me to learn all about this stuff. I am interested in knowing more, because at the moment its like another language…
Thanks for your help, all up and running 
Much easier than I expected.
This place is a great resource, if you read and learn from other peoples posts/problems/code samples 
Just to confirm - the UCS2903 is working for you when you refer to the leds as WS2811 in the code? (If so, i’ll add a UCS2903 alias for WS2811 in there so that you can reference the chipset you are actually using
As for resources - there’s this community - there’s the documentation wiki - http://fastled.io/wiki - and there’s example code that @Mark_Kriegsman and I are hoping to build on and expand.
Hi Daniel
When I use the ws2811 in the code I can operate the chasing rgb and it seems to operate as it should. I haven’t done Any custom coding yet but at this stage it’s looking like it will work fine.
Thanks for the links and your help. I’ll post some pics of what I’m using it for when I’ve finished.
Previously to do this type of thing we used dmx and a decoder but I’m trying to simplify and streamline the components required for smaller projects.
