Driving WS2812 neopixel led strip

[hansamann]

Hi all,

I am trying to use the LoPy 1.0r with the latest firmware and some NeoPixels - found this lib:
https://github.com/aureleq/wipy-lopy-WS2812

from ws2812 import WS2812
from utime import sleep_ms

chain = WS2812( ledNumber=1, brightness=50, dataPin='P22' ) # dataPin is for LoPy board only
data = [(255, 102, 0)]
chain.show( data )


while True:
    chain.show( data )
    sleep_ms( 150 )

Unfortunately just nothing happens. Has anyone succeeded in using the LoPy with the latest firmware to drive some neopixels?

thx
Sven
