hi guys, I’m looking for a solution to use 2 led-rings, one with 16 leds the other with 24 leds as a 2d matrix to use 2d effects. the rings are configured as a 40 led stripe right now, but that makes no use of 2d effects. Has anyone an idea on that or are there any solutions that I was unable to find via forum search?? Any help appreciated… have a good one - cheers Dan ---

An example of mapping 241 rings as 17x17 matrix is here , [Discord](https://discord.com/channels/473448917040758787/801531333067014164/1116487765203374100) , i have also tested with less leds and its the same process and result is the same [Discord](https://discord.com/channels/473448917040758787/801531333067014164/1078979082345271327) ---

Hi, thanks, but I’m unsure if you got me right… one ring is smaller than the other (less leds) so to match up a matrix when placing the smaller inside the bigger, a ratio of 2/3 leds is neccesary to match the same color on both rings. I can’t open your discord links by the way, sorry and my rings are WS2812 leds… Dan ---

when I open this address: …[Discord](https://discord.com/channels/473448917040758787)… I only get an announcement: You are at a weird place, and either you got no access to a text channel or there are no text channels on the server… (freely translated from german) because my discord uses german language, sorry ??? I don’t know what went wrong using your link… ---
