#include "U8glib.h"

U8GLIB_NHD_C12864 u8g(13, 11, 10, 9, 8);    // SPI Com: SCK = 13, MOSI = 11, CS = 10, CD = 9, RST = 8

  u8g.drawStr( 0, 20, "www.DFRobot.com");
}

void setup(void) {
  u8g.setContrast(0); // Config the contrast to the best effect
  u8g.setRot180();// rotate screen, if required
  // set SPI backup if required
  //u8g.setHardwareBackup(u8g_backup_avr_spi);

  // assign default color value
  if ( u8g.getMode() == U8G_MODE_R3G3B2 ) {
    u8g.setColorIndex(255);     // white
  }
  else if ( u8g.getMode() == U8G_MODE_GRAY2BIT ) {
    u8g.setColorIndex(3);         // max intensity
  }
  else if ( u8g.getMode() == U8G_MODE_BW ) {
    u8g.setColorIndex(1);         // pixel on
  }
  else if ( u8g.getMode() == U8G_MODE_HICOLOR ) {
    u8g.setHiColorByRGB(255,255,255);
  }
}

void loop(void) {
  // picture loop
  u8g.firstPage();
  do {
    draw();
  }
  while( u8g.nextPage() );

  // rebuild the picture after some delay
  delay(500);
}
