Addressable RGB LED (WS2812B)

   Hi Guys,

I cannot get the addressable RGB LED strip working properly , only one LED work . I have two stripe and the two strip have the same issue.

The motherboard is the Asrock x470 Master SLI/ac. I use the polychrome application v1.0.11, if I setup the good amount of addressable LED only one LED light up with the good color, if I set the number to 7 the RGB stripe LED stop working, if I put less than 7 the LED under the chipset stop working too...

I have plug a logic analyser on the addressable RGB LED strip. My observation was that only 24 bit of data was send each time. Normaly for this kind of RGB addressable LED it's [24 bit x Number of LED]. So for my case 24 bit x 22 LED = 528 bits of data.

So I think that is a software problem...

I try bios v1.00, v1.10 and v1.15 without change.

Someone of you have I solution for my problem?

Thanks ,

	Try to flash the LED firmware under Windows: http://forum.asrock.com/forum_posts.asp?TID=4537&PN=3&title=rgb-led-issues That should fix the problem. I had a similar issue as well when I first setup the board. Edited by akirabbq - 07 Jun 2018 at 10:48pm
