Espruino with Glediator & LED matrix

I had a to change a few little bits. For example I had to remove the call to onInit(); other wise the serial on(data) was getting fired twice on boot which messed up the output.
I also added a frame per second counter for testing and I get a steady 25 fps!
My next task maybe to try and get this working over USB alone but if I need console access this might not be possible. maybe I could move console onto Bluetooth..
Here is the full code used in the video:

  var fps = 0;
  function onInit() {
    SPI2.setup({baud:3200000, mosi:B15});
    var cmd = "";
    Serial3.setup(1000000, {tx:C10,rx:C11});
    Serial3.on('data', function (data) {
      cmd+=data;
      var idx = cmd.indexOf("\1");
      while (idx>=0) {
        var line = cmd.substr(0,idx);
        cmd = cmd.substr(idx+1);
        idx = cmd.indexOf("\1");
        SPI2.send4bit(line, 0b0001, 0b0011);
        fps++;
      }
    });
    
    var fps = setInterval(function() {
      console.log('fps: ' + fps);
      fps = 0;
    }, 1000);
  }
