kaleidoscope VS FastLED

I have a project that runs on the ESP32 and uses two interrupt driven rotary encoders. You can find the source on https://github.com/benpeart/kaleidoscope. It's not a simple sample but most of the code has nothing to do with the rotary encoders and can be ignored. Look at the code inside the '#ifdef ENCODER' in main.cpp for how to initialize and use the encoders.

I added 3 .22 uf capacitors (one each between CLK, DT, SW and ground) to try and make them a little less noisy but I can't notice any difference between when they are there or not. On the software side, I'm using the Bounce2 library to debounce the switches and am using a state machine library I based on Oleg Mazurov's code (see the implementation on GitHub) for the rotary encoders.

I'm building a digital Kaleidoscope (source) using FastLED running on an ESP32. I added AsyncElegantOTA and found that any attempt to do an OTA updated resulted in a crash:

I'm working on a project where I have 4 WS2812B LED strips hooked up to a Teensy 4.0. I've set it up using the instructions for parallel output on pins 19,18,14,15 but I'm having issues where often, the LEDs don't update properly or sometimes at all. Even something as simple as a FastLED.clear(), FastLED.show() won't actually show the cleared LEDs.

I used the examples from here https://github.com/FastLED/FastLED/wiki/Multiple-Controller-Examples

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.
