FastLED and Webserver crashlooping #257

Closed gelicia closed 1 year ago

gelicia commented 1 year ago

Hello, I checked out this project because I was unable to keep a server stable doing something similar with Webserver and FastLED, just wanted to see if someone could see something I'm missing.

I've stripped out all actual LED functionality to try to figure out what the issue could be. I've included the code for the two files I use after removing all the other code.

Running the ESP32C3 Dev Module.

Serial crash logs
This happens continuously. It stops if I remove the `FastLED.addLeds` call from setup. ``` 11:06:53.607 -> HTTP server started 11:06:54.360 -> Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0). 11:06:54.360
