Attempting to use the adalight sketch and I can't get the strand to light at all
using 5v 2a wall wort for the psu on pixels n using octows2811 break out board with a teensy 3.1
Expect to see the test patterns but for some reason I can't get the pixels to light
I did jump pin 15/16 as the commented code suggests but it did not change behavior
if anyone can help please let me know it would be greatly appreciated.
I also noticed in the sketch you have for adalight it doesnt really define an "output" pin

Required Connections http://www.pjrc.com/store/octo28_adaptor.html
--------------------
pin 2: LED Strip #1 OctoWS2811 drives 8 LED Strips.
pin 14: LED strip #2 All 8 are the same length.
pin 7: LED strip #3
pin 8: LED strip #4 A 100 ohm resistor should used
pin 6: LED strip #5 between each Teensy pin and the
pin 20: LED strip #6 wire to the LED strip, to minimize
pin 21: LED strip #7 high frequency ringining & noise.
pin 5: LED strip #8
pin 15 & 16 - Connect together, but do not use <<< I have done this
pin 4 - Do not use
pin 3 - Do not use as PWM. Normal use is ok.
