Hello,

I'm totally newbies with Espruino and i'm trying to display my converted image on my SSD1306 but no success.

I tryed several times but it don't work.

This my code :

var mylogo = {
  width : 34, height : 38, bpp : 1,
  transparent : 1,
  palette : new Uint16Array([65535,65535]),
  buffer : E.toArrayBuffer(atob("//4f////A////4B////AD///4AH///AAP//wAAP/gAAAB4AECABAAQIAAACAQAAA4BwAAHADgAAcAOAIDgAcBgODBwHB4MDg8HAwODwcHg4PBgeBg8GAAGDwQAAIOBAAAgYAAAABAAf4AAAD/wAAAP/AAAA/8AAAE/IAIAAAAB4AAAAf/AAA///AAP//+AB///8AP///4B////wP////h//w"))
};

  function LogoDisplay(){
    if (!display) {
      NumControl();
      return;
    }
    var x1x2 = 1;
    g.clear();
    g.drawImage(mylogo, 15, 15);
    g.flip();
    var preloader = setInterval(function () {
      g.setContrast(x1x2);
      g.drawLine(x1x2, 50, x1x2, 60);
      x1x2 += 2;
      g.drawLine(x1x2, 50, x1x2, 60);
      x1x2 += 2;
      g.drawLine(x1x2, 50, x1x2, 60);
      x1x2 += 2;
      g.drawLine(x1x2, 50, x1x2, 60);
      x1x2 += 2;
      g.drawLine(x1x2, 50, x1x2, 60);
      x1x2 += 2;
      g.drawLine(x1x2, 50, x1x2, 60);
      x1x2 += 2;
      g.flip();
      if (x1x2 > 126) {
        clearInterval(preloader);
        NumControl();
        StartDisplay();
        wifiConnect();
      }
    }, 10);
  }
