Wii Nunchuck

I have now tested my Wii Nunchuck on my Pico and esp8266, and now I have it running on both.
I had to set the freq to 80 on esp8266 and put in a few delay's.

// nunchuk_03 -     pico - esp8266-01

//White:	Gnd  -  Gnd
//Red:		3V3  -  Vdd
//Yellow:	SCL  -  B6  -  D0
//Green:	SDA  -  B7  -  D2


function Wait(ms) {
  var a = Date().getTime() + ms;
  while(Date().getTime() < a) {}
}

var d;
var a;

(function() {
  var tg = 0x2F; // 0x2F ^ 0x73 = 0x5C
  var esp8266 = true;

  if(esp8266) {
    // esp8266
    var ESP8266 = require('ESP8266');
    ESP8266.setCPUFreq(80);
    pinMode(D0, 'opendrain'); // scl
    pinMode(D2, 'opendrain'); // sda
    I2C1.setup({scl:D0,sda:D2});
  }
  else {
    // pico
    I2C1.setup({scl:B6,sda:B7});
  }

  // pico and esp8266-01
  var i2c = I2C1;
  i2c.writeTo(0x52, [0xF0, 0x55]);
  Wait(11);
  i2c.writeTo(0x52, [0xFB, 0x00]);
  Wait(11);

  setInterval(function() {

    i2c.writeTo(0x52, [0x00]);
    Wait(1);
    d = i2c.readFrom(0x52, 6);
    tg ^= 0x73;
    console.log(d, ' ', String.fromCharCode(tg));
    console.log({
      joy : {x:d[0],y:d[1]},
      acc : {x:(d[2]<<2)+((d[5]>>2)&3),
             y:(d[3]<<2)+((d[5]>>4)&3),
             z:(d[4]<<2)+((d[5]>>6)&3)},
      btn : {z:!(d[5]&1),c:!(d[5]&2) }
    });

  },500);

})();
