Adafruit_TLC5947.h

/*************************************************** 
  This is a library for our Adafruit 24-channel PWM/LED driver

  Pick one up today in the adafruit shop!
  ------> http://www.adafruit.com/products/1429

  These drivers uses SPI to communicate, 3 pins are required to  
  interface: Data, Clock and Latch. The boards are chainable
