ESP8266 - Nokia PCD8544 Display

Thanks for you help @Wilberforce it now works! It worked on direct upload in the beginning, then I figured out the pin setup via dump() and now I got it working with the following code:

var DISPLAY_CONTRAST = 0.49;
var LINE_HEIGHT = 6;

digitalWrite(D2, 0);
digitalWrite(D4, 0);
digitalWrite(D5, 0);
pinMode(D0, "input_pullup");
pinMode(D12, "input_pullup");
pinMode(D13, "input_pullup");
pinMode(D14, "input_pullup");
digitalWrite(D15, 0);

function drawText(oDisplay, aText, iX, iLineHeight) {
  aText.forEach(function (sLine, iIdx) {
    oDisplay.drawString(sLine, iX, iLineHeight * iIdx); 
  });
}

function begin () {
  SPI1.setup({ sck:D14, mosi:D13 });
  var g = require("PCD8544").connect(SPI1,
    D4 /* RS / DC */,
    D15 /* CS / CE */, 
    D5 /*RST*/, function() {

    g.clear();
    g.setContrast(DISPLAY_CONTRAST);
    g.setRotation(2); //Flip display 180
    drawText(g, [
      "Line 1",
      "Line 2",
      "Line 3",
      "Line 4",
      "Line 5",
      "Line 6",
      "Line 7",
      "Line 8"
    ], 0, LINE_HEIGHT);
    g.drawLine(30, 0, 84,48);
    g.drawLine(30, 48, 84, 0);
    g.flip();

  });
}

E.on("init", begin);
save();

It looks amazing! so thanks again for your help!
