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?
