Guru Meditation Error if more than 2 Pins/ 2 controller are used with filehandling
I used the examples from here https://github.com/FastLED/FastLED/wiki/Multiple-Controller-Examples
- FastLED's newest feature - HD mode for the APA102/SK9822/Dotstar LEDS
- High Bit Depth Gamma Correction Algorithm for APA102/Dotstar LEDs
- Is there an alternative to using two WS2811 ics to control RGBW channels [first image], and are there any adjustments needed for the current regulator circuit [second image] ?
- Frames getting stuck with ESP32 and 16 by 16 LED Matrix
- changing brightness of the individual led's?
- Arduino Due SPI to control LED strip(s)
- Powering 300 LEDs w/ battery
- led_sysdefs_avr.h error

Multiple RGB outputs
Sweet. Then pretty much any arduino or other microcontroller would take care of what you need. The strips only take one output pin plus power and ground so just about everything will work for driving them. They act like a long shift register so the single pin is all that's needed to load the full strip with whatever patterns you want regardless of the length. You just have to tell it how many LEDs there are in total is all. Check out the FastLED library. You can learn more about it there and/or install the library in the IDE by pressing "ctrl shift I" for windows or "command shift I" for mac and search for it in the upper search area and install it right there. It comes with working examples too so all you would have to do is install the library, load one of the new example sketches that came with it, and probably edit the example to change the NUM_LEDS count to match what you're working with.

RGBW but ignore the W channel... trying to use fill_palette
Exactly. /u/zumdar the result would be the function at the bottom of FastLED_RGBW.h in this sketch. There is also this with many FastLED operators and some functions modified for RGBW.

Small update to the 1-D firework sparks from earlier
I've done a whole write up on the build here

Best RGBWW or WW strip?
I used the FastLED hack for white LEDs and it worked fine. The code for my lamp is here
-
Does FastLED support RGBW?
I tried the hack out myself and it works fine if in a somewhat limited capacity. That said, I've expanded the hack to include more functionality

Thought about FastLED and RGBW
scroll down this page to see my findings on SK6812 led ribbons. Basically, I started with the hack that u/Johnny5canuck pointed out and have considerably extended it as and where needed.

Cheap 8x8 matrix compatible with Fastled?
It's possible, but hacky, to drive RGBW with FastLED. Be sure to follow the links at the top of that file for more information. Only a small selection of FastLED's functions have been modified to work with the RGBW type. Those that have been modified haven't necessarily been changed in the most appropriate and optimal ways to get the best out of RGBW.

Will this high brightness LED strip work with an arduino and FastLED?
Generally you are quite right but I found a workaround (hack) that works just great with my lamp here is the code you just need to add.
