TMP102 module

I created this module today. It allows Espruino board to interface with a TMP102 temperature sensor. It is accurate down to 0.0625 of a degree.

I2C1.setup({scl:B6,sda:B7});
var TMP102 = require("tmp102").connect(I2C1);
console.log(TMP102.getTemperature());

 
function TMP102(_i2c) {
    this.i2c = _i2c;
    this.address = 0x48;   
}

TMP102.prototype.getTemperature = function() {
    var self = this;  
    var d = self.i2c.readFrom(self.address, 2);
    var temp = (((d[0] << 8) | d[1]) >> 4)*0.0625; 
    return temp;
};


exports.connect = function (_i2c) {
    return new TMP102(_i2c);
};

Great! Thanks! Would you like me to put it in with the Espruino modules, or would you like to do it? instructions here

Here a little example. I clean and reduce a little bit the code. Some var definitions are not needed.

/* Copyright (c) 2014 ToDo */
/*

var C = {
  ADDRESS : 0x48    // description
};

/**
 * Description
*/
function TMP102(_i2c) {
    this.i2c = _i2c;
}

/**
 * Description
*/
TMP102.prototype.getTemperature = function() {
    var d = this.i2c.readFrom(C.ADDRESS, 2);
    return (((d[0] << 8) | d[1]) >> 4)*0.0625; 
};

/**
 * export
*/
exports.connect = function (_i2c) {
    return new TMP102(_i2c);
};

I will attempt to add this at the weekend.

Thanks!
