Optimised fork of bikeNomad's WS2811 LED control library. Supports KL25Z and KL46Z
Fork of Multi_WS2811 by
Optimised to use far less RAM than the original.
Capable of running up to 8 strings of 240 LEDs each with plenty of RAM to spare on the KL46Z.
Should run at least three strings of 240 LEDs on the KL25Z (RAM limited)

bikeNomad | 0:a8535703f23b | 13 | * can be any floating-point number. The floor of this number is |
bikeNomad | 0:a8535703f23b | 14 | * subtracted from it to create a fraction between 0 and 1. This |
bikeNomad | 0:a8535703f23b | 15 | * fractional number is then multiplied by 360 to produce the hue |

bikeNomad | 0:a8535703f23b | 19 | * value of a color in bits 0-23 of an integer value that is the same |
bikeNomad | 0:a8535703f23b | 20 | * format used by the method {@link #getRGB() <code>getRGB</code>}. |
bikeNomad | 0:a8535703f23b | 21 | * This integer can be supplied as an argument to the |
