Hi, FastLED allows for custom ordering of pixels - allows for runnings effects on a strip out of order. I know there’s some basic Matrixing within NPB, but given it appears remapping is a reasonably easy process (create an array of custom order containing 0 to n, where n = num leds, then read back…

Abmibox also does the same for TV backlighting. But they have done it in groups, and you set how many LEDs are in a group, you can then order the groups however you like. This is useful on corners and joins Theres a bit of trial and error to figure out where your LEDs are but it works quite well. …

Hi, I just added this to the latest master! Just replace the mapping array in the top of FX_fcn.cpp with your mapping (in the case we discussed on Discord I believe you’d want the contents of the fibonacciToPhysical array) and uncomment the #define WLED_CUSTOM_LED_MAPPING :slight_smile: This is j…

Spectacular. I guess the next logical step is to make it a runtime option! Here’s what I’ve done with it so far - this is using WLED + LedFX + Jason Coons Fibonacci256 board. Still need to make a case for it! 2 …

Looks amazing! I want a fibonacci setup as well, have to build one soon! Yeah, having it runtime configurable would be ideal, but that might be a bit complicated and cost some memory, but we’ll see :slight_smile:

Looks great! Is there a write up on how to use this anywhere?
