Espruino with Glediator & LED matrix

Hi,
I think this is the working code but haven't tested it in a while. Read the comment at the top for the wiring, matrix and Glediator settings.
Let me know if that works or not. I was using the Pico but it shouldn't matter which espruino you use.

/**
Glediator settings
Driver: Glediator
COM6
Baud 1000000

Pixel order:  HS_TL
*/
var fps = 0,
    buf = new Uint8Array(15*15*3),
    bufIdx = 0,
    cmd = "";

function onInit() {
  SPI1.setup({baud:3200000, mosi:A7});
  
  Serial1.setup(115200, {tx:B6,rx:B7});
  Serial1.on('data', function (data) {
    
    buf.set(data, bufIdx);
    bufIdx += data.length;
    
    if (data.indexOf("\1") >= 0) {
      var idx = bufIdx + data.indexOf("\1");
      var line = new Uint8Array(buf.buffer, 0, idx);
      console.log(idx);
      
      SPI1.send4bit(line, 0b0001, 0b0011);
      buf.set(new Uint8Array(buf.buffer, idx, bufIdx-idx), 0);
      bufIdx -= idx;
      fps++;
    }
  });
    
  var fps = setInterval(function() {
    console.log('fps: ' + fps);
    fps = 0;
  }, 1000);
}

onInit();
