Using setInterval to update scroller items

This should work with the latest firmware:

    var list = [];
    list[0] = 10;
    list[1] = 20;
    list[2] = 30;
    list[3] = 40;
    list[4] = 50;
    list[5] = 60;
    list[6] = 70;
    var s = E.showScroller({
      h : 40, c : list.length,
      draw : (idx, r) => {
        g.clearRect(r.x,r.y,r.x+r.w-1,r.y+r.h-1)­;
        g.setFont("6x8:2").drawString(list[idx],­r.x+10,r.y+4);
      },
      select : (idx) => console.log("You selected ", idx)
      }
    );
  setInterval(function(){
      list = list.map(i => i-1);
      s.draw();
  }, 1000);
