E-paper GDEP015OC1 display

I am able to run the display using arduino using GxEPD2 lib. But I can't get it work with Espruino :(,

this is the code I am using, can some one help me getting the display to work?

var spi;
var display;

function setupSPI(){
  console.log('starting SPI');
  spi = new SPI();
  spi.setup({ sck:D14, mosi:D13 });
  display = require('SSD1606.min').connect({
      display: {
        bpp : 1,
        displaySizeX      : 200,
        displaySizeY      : 200,
        lutRegisterData   : new Uint8Array([0x10, 0x18, 0x18, 0x08, 0x18, 0x18, 0x08, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x13, 0x14, 0x44, 0x12, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00]), // PARTIAL update lutRegisterData, covered further
        maxScreenBytes    : 5000, // this
        ramXStartAddress  : 0x00, // this
        ramXEndAddress    : 0x18, // this
        ramYStartAddress  : 0xC7, // this
        ramYEndAddress    : 0x00 // and this
      },
      spi        : spi,
      cs1Pin     : D15,
      dcPin      : D0,
      resetPin   : D2,
      busyPin    : D4,
//      powerPin   : B15
  });
  //display.on();

display.hwReset(function(){
    display.init(
      function(err){
        display.g.clear(0xFF);
        display.g.setRotation(1);
        display.g.setColor(0x00);
        display.g.setFontVector(20);
        display.g.drawString('Hello World!', 22, 22);
        display.g.flip();
        display.refreshScreen(function(err){
          display.off();
        });
      },
      { clearScreenColor: 0x00 }
    );
  });
}



function start() {
  setupSPI();
}

E.on('init', start);
