PCD8544 - attempts to fix module running into strange js behavior

Umm... So I tried your new module - and yes, it's completely broken.

But the code that I had before (without the extra 2 bytes at the end at all) works perfectly on software SPI. Perhaps it's actually an issue with Espruino's SPI and how quickly it raises the CE line after sending.

Try:

  LCD.flip = function () {
    ce.reset();
    for (var i=0;i<6;i++) {
      digitalWrite(dc,0); // cmd
      spi.send(0x40|i); // Y addr
      spi.send(0x80); // X addr
      digitalWrite(dc,1); // data
      spi.send(new Uint8Array(this.buffer,i*84,84));
    }
    ce.set();
  };
