  Required Connections
  --------------------
    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
    pin 4 - Do not use
    pin 3 - Do not use as PWM.  Normal use is ok.

  This test is useful for checking if your LED strips work, and which
  color config (WS2811_RGB, WS2811_GRB, etc) they require.
