nodemcu + sparkfun micro oled display issue

[uranium235]

I'm having some problem with the NodeMCU and the micro oled display breakout board from sparkfun,
everything works but i noticed that i does not display any text at all, i tried this with the sample code that they provide.
Another problem is that in the demo code this part

Code: [Select]

void pixelExample()
{
  printTitle("Pixels", 1);
 
  for (int i=0; i<512; i++)
  {
    oled.pixel(random(oled.getLCDWidth()), random(oled.getLCDHeight()));
    oled.display();
  }
}

causes the nodeMCU to display this message on the serial port

I'm using arduino IDE to write the code for nodeMCU, and the NodeMCU and the oled display is connected via SPI.
