    This is a demo for the WS2812 LED driver library.

    The the timings of the bit banging operation are very sensitive. Depending on the platform, you will need to change the timing values in the WS2812 constructor. The default values in this demo are for the K64F. Here are a few other values for other platforms:

    K64F, KL46Z: 0, 5, 5, 0

    LPC1768: 5, 10, 10, 15

    NUCLEO F411RE: 7, 15, 10, 15

    UPDATE 11-29-2016

    Thanks to the user Proff for the new measurements!

    LPC1768: 3, 11, 10, 11

    NUCLEO_F401RE: 3, 12, 9, 12

    UPDATE 3-14-2017

    Thanks to the user SashaK for the new measurements

    NUCELO_F746ZG: 32, 105, 70, 123

    If you are curious how to determine these values, see the WS2812 library page below.
