Hi JoDaNI. (This is not an issue, just a comment)

I have created a LED table consisting of 100 leds, which I can control from my smartphone. Im using a lot of different libraries, including https://github.com/Links2004/arduinoWebSockets, and on my html page I have a slider, which sends A LOT of request to the poor little ESP when someone drags a finger across to change the color of the table. However I have had one consisting problem (the past 2 months) in which my esp would simply restart when having to update the 100 LEDs as fast as the data comes in. I have tried using both NeoPixelBus and Adafruits NeoPixel library, which have both crashed the esp.

However... I just tried your library. And now my esp is ROCK SOLID! Thank you so much! (And also cnlohr) for making this possible.

You're welcome...nice to hear you're having success !

Ha, same issue here. I'm running a Philips Hue clone using https://github.com/KhaosT/HAP-NodeJS to emulate the HomeKit API. Moving the slider does make my strip go crazy at times. Just added HSV support to this library and deployed it. Lets see how it goes.

Another problem I'm still able to reproduce is sometimes the farther end of the strip (94 pixels) becomes white, and stays like that no matter what you do until you reboot the strip. I was suspecting it was a library issue but happens with this library too. So probably an electrical issue.

Thats sounds nice! I think i'll try that library, too. I have 100 led's in a strip, and I have not once seen anyone of them get stuck in a color. So yea, I guess you a correct, and that you have some kind of electrical issue.

@JoDaNl, can you explain i2s frequency setup? Did you understand this?
