 +//Adafruit_NeoMatrix example for single NeoPixel Shield.
 +//Scrolls 'Howdy' across the matrix in a portrait (vertical) orientation.
 +#include <Arduino.h>
 +#include <Adafruit_GFX.h>
 +#include <Adafruit_NeoMatrix.h>
 +#include <Adafruit_NeoPixel.h>
 +#ifndef PSTR
 + #define PSTR // Make Arduino Due happy
 +#endif

 +#define PIN D3
 +
 +// MATRIX DECLARATION:
 +// Parameter 1 = width of NeoPixel matrix
 +// Parameter 2 = height of matrix
 +// Parameter 3 = pin number (most are valid)
 +// Parameter 4 = matrix layout flags, add together as needed:
 +//   NEO_MATRIX_TOP, NEO_MATRIX_BOTTOM, NEO_MATRIX_LEFT, NEO_MATRIX_RIGHT:
 +//     Position of the FIRST LED in the matrix; pick two, e.g.
 +//     NEO_MATRIX_TOP + NEO_MATRIX_LEFT for the top-left corner.
 +//   NEO_MATRIX_ROWS, NEO_MATRIX_COLUMNS: LEDs are arranged in horizontal
 +//     rows or in vertical columns, respectively; pick one or the other.
 +//   NEO_MATRIX_PROGRESSIVE, NEO_MATRIX_ZIGZAG: all rows/columns proceed
 +//     in the same order, or alternate lines reverse direction; pick one.
 +//   See example below for these values in action.
 +// Parameter 5 = pixel type flags, add together as needed:
 +//   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
 +//   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
 +//   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products)
 +//   NEO_GRBW    Pixels are wired for GRBW bitstream (RGB+W NeoPixel products)
 +//   NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
 +
 +
 +// Example for NeoPixel Shield.  In this application we'd like to use it
 +// as a 5x8 tall matrix, with the USB port positioned at the top of the
 +// Arduino.  When held that way, the first pixel is at the top right, and
 +// lines are arranged in columns, progressive order.  The shield uses
 +// 800 KHz (v2) pixels that expect GRB color data.
 +// Adafruit_NeoMatrix matrix = Adafruit_NeoMatrix(16, 8, PIN,
 +//   NEO_MATRIX_TOP     + NEO_MATRIX_LEFT +
 +//   NEO_MATRIX_COLUMNS + NEO_MATRIX_PROGRESSIVE,
 +//   NEO_GRB            + NEO_KHZ800);
