Need a trippy color spiral for your matrix? I gotcha covered.
I'm not aware of any general significance of DrawOneFrame functions. They don't invoke any particular FastLED behaviour. For projects where a variety of different effects can be presented, the author may choose to use C++ classes to provide a standard interface to initialise and display those effects. In my WavyDots sketch, that function name is a vestige of such a choice. The Aurora project does something similar. So does the Striptease project, but there the DrawOneFrame function is simply called loop.

Feature Request: "Invisible" LEDs
Hi, I faced the same problem in my project.
-
Is FastLed compatible with Teensy 3.x or 4.x?
That's what I'm using in my project based on Teensy 4.1 + Audio shield for driving 6 channels in non-blocking mode and it works great!
-
Teensy 4.0 serial problem with FastLED
I'm using it in my project for driving 6 channels (Teensy 4.x) without any problems.
-
Unable to get FastLED 3.4 working on multiple strips in parallel with Teensy 4.0
If you plan to use the Audio shield in your project (as I do on mine), then two Serial ports won't be available (pins 8 and 20), leaving you with 3 and 6 serial ports available on standard pins.
-
How can I get patterns to "skip" sections of a LED strip?
I have developed a library/framework for this, and it allows decoupling the physical layout of your strips (up to six) from the logical layout.
-
audio reactive patterns
I've developed a library for that, but it requires Teensy 4.0 or Teensy 4.1 + Audio board.

Hi everyone, which cheap & available controller is a good choice at the moment? Requirements: 200+ MHz & FastLED hardware SPI support. I've an ESP32 V4 in mind. Or maybe an ESP32-S3FN8. Any experiences, comments or suggestions? What is widely used currently?
I highly recommend the Teensy 4.x with the OctoWS2811 driver. This driver provides 8 channels of parallel output using DMA data transfers to offload the CPU. I think that meets your criterion for "hardware SPI". It doesn't seem like the T4 is overkill for what you're doing, especially if you're using floating point math. The T4 is blazing fast, and I've heard mixed reviews of ESP32 FP performance.

New to this. Suggestions for controlling 2,016 WS285 LEDs?
Assuming you're going to use the OctoWS2811 library to drive the LEDs, the maximum possible frame rate for 2 channels of 1,008 LEDs should be:

Any tutorials for attaching & controlling a WS2815 to computer's PSU PCIe 6+2?

Thought about FastLED and RGBW
I've used RGBW for a number of projects involving non-addressable LED strips and spot lights. I haven't yet needed RGBW for a project requiring addressable strips, but it's in my tech roadmap. I no longer use FastLED, and I've written my own HSV/HSI-to-RGB/RGBW color conversion library. I use the OctoWS2811 library (not the adapter board) for DMA-based serial data output to addressable LED strips. It appears that this library supports RGBW strips, but I haven't tried it yet (others are doing the same). See the last few paragraphs of this article for more details.
- Future Octows2811 RGBW compatability??
-
Testing diffusion technique (WS2818B LED strips)
It's not Paul's OctoWS2811 (on a Teensy), is it? It's been around for ages, so I assume it's something else, but just in case.
-
Is FastLed compatible with Teensy 3.x or 4.x?
A very good alternative to OctoWS2811 is the WS2812Serial library, by Paul Stoffregen too.
-
Unable to get FastLED 3.4 working on multiple strips in parallel with Teensy 4.0
Has anyone been successful getting it to work using FastLED with OctoWS2811? With only 4 strips of 156 LEDs, I didn't think I needed to go this far but at this point, am willing to try anything to get it to work.
What are some alternatives?
