Re: WS2812B RGB LED Driver

Hello.

I've got strange problem. The 1st led in strip (ws2811) randomly turning on green color. Even if I send black to all strip repeatedly 10 times per sec - it will blink by green color like 2-3 times per sec.

I tried same strip with Arduino's FastLed - all working fine.
I tried to add capacitor between VCC and Gnd - no effect.
I tried to add resistor between Din and GPIO - no effect.

Any ideas?

This was a bug present in the early versions. quite a bit of hunting went into fixing it.

Gab this, and you should have no more blinking!

You will probably know is there any way to light 60 leds (with diferent color) with lua code?

I have gone through your discussion and want to know that what is required to integrate a feature for which C code is already available?
What sort of plumbing is needed?
Which stuff should be inside nodemcu - consuming precious space for everyone and which should be in userland?
