I am trying to control some ws2811 pixels using the adafruit neopixel library. https://github.com/adafruit/Adafruit_NeoPixel When I use an arduino uno they work fine but when I import the library and flash the code on udoo nothing lights up. http://www.adafruit.com/products/1426 these are the neopixels that I am using. I have taken care of the basic things like power and connections. I basically set the exact same setup as in the arduino but they dont seem to light up. I could post detailed pictures of my setup. I tried with a basic led TLHB4201 datasheet: http://www.kynix.com/uploadfiles/pdf9675/TLHB4201.pdf and that seems to light up. But neopixels don't work. http://forums.adafruit.com/viewtopic.php?f=47&t=40547&p=258419#p258419 The forum from adafruit says the library works with the due and they dont mention anything about the level shifter, I even posted in the forum but no one responded back. If anyone can help me I will be thankful
