Richard Thompson / Multi_WS2811

Optimised fork of bikeNomad's WS2811 LED control library. Supports KL25Z and KL46Z

Dependents:   CubicHand

Fork of Multi_WS2811 by Ned Konz

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)
