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...

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...
