Leider habe ich Probleme die Library fehlerfrei in meine IDE einzubinden bzw. selbst der
Beispiel-Code funktioniert nicht.
Ich nutze die 1.8.0 bzw. 1.8.8 auf meinem Mac und dazu Adafruit Neomatrix Ver. 1.1.2.
Als Hardware nutze ich einen Asia Arduino Nano mit einem ATmega328P (Old Bootloader).
Als Fehlermeldung bekomme ich
Arduino: 1.8.8 (Mac OS X), Board: "Arduino Nano, ATmega328P (Old Bootloader)"

/Users/xxx/Documents/Arduino/libraries/Adafruit_NeoMatrix/Adafruit_NeoMatrix.h:72:5: error: 'neoPixelType' has not been declared
neoPixelType ledType = NEO_GRB + NEO_KHZ800);
Allerdings benutze ich auch kein original Adafruit Neopixel Produkt sondern eine einfache Matrix
mit 16x16 WS2812 LEDs.
Die Ausgabe mit der Adafruit_NeoPixel Library läuft allerdings ohne Probleme.
Hier der Code
// Adafruit_NeoMatrix example for single NeoPixel Shield.
// Scrolls 'Howdy' across the matrix in a portrait (vertical) orientation.

#define PSTR // Make Arduino Due happy
#endif
#define PIN 8
// 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_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.
