Fastled: WS2812B, flickering, wrong colors

[gioalex]

Hi,
using fastled library 3.0.1 I have the same issue presented in this link:

https://code.google.com/p/fastspi/issues/detail?id=37

I'm using arduino ide 1.0.6 and arduino nano.

Any suggestions ?

thank you very much.

There's a lot of things that can cause this - often wiring/power variations. For example, if your voltage into the led strip is above 5.25-5.3v that will cause flickering problems. Also - make sure that ground on the led strip is connected to both the power supply and to the nano as well.

You are totally right.

Voltage is 5v regulated by a LM317.... but I don't checked the second thing, the ground.
Now everything is working in the right way.

I apologize for the unnecessary reporting problems.
