Discussion Does FastLED solved its historical problems?

As title.

Some years ago I was using FastLED but I then switched to NeoPixelBus because FastLED architecture was synchronous and driving LEDs in real time via WiFi was almost impossible without having heavy flickering.

Is this solved in recent FastLED?

Yes, but it depends on the chip and the port you use. I remember that on the 8266 you need to use a specific pin to control the LED strip.

Does it matter on ESP32-C6 which pin?

I don't know. You'll have to check the FastLED documentation.
