Re: Adafruit NeoPixel FeatherWing -- np.fill(0,0,0) = dim not blank!
I discussed this with Damian George (the author of MicroPython), via a github bug report. SOLUTION: Raise the clock speed on the Feather from 80MHz (default) to 160MHz. Likely this impacts power consumption but this cures this nasty np.fill((0,0,0)) = dim not off problem Just add these links of code...

Re: Driver for WS2812 RGB LEDs (NeoPixels, ...)
Have you seen the Adafruit MicroPython + NeoPixel video

Re: Adafruit NeoPixel FeatherWing -- np.fill(0,0,0) = dim not blank!
The Feather board is powered by USB cable to USB3.0 port on my laptop There seems to be enough juice as the board will happily display (255,255,255) -- all LEDs on full which should draw more current. I've seen insufficient power situations cause the CPU to crash when the current draw goes too high ...

Adafruit NeoPixel FeatherWing -- np.fill(0,0,0) = dim not blank!
Maybe I'm doing something wrong but I wanted to check here. Maybe this is NeoPixel driver bug, maybe I'm just messing up somewhere Board = Adafruit ESP8266 Feather, reflashed with 1.8.4 (using NodeMCU flasher - I know that's not the officiial tool) LED board is Adafruit NeoPixel FeatherWing -- 4x8 m...
