ADS1115 analog gain signal module - how to run it with espruino?

I have also just put the ADS1X15 module onto the website, so you no longer need all the code I posted. You just need:

I2C1.setup({ scl : ..., sda: ...} );
var ads = require("ADS1X15").connect(I2C1); // <--- this now pulls everything from the internet
ads.setGain(256); // +/- 0.256mV
ads.getADC(0, function(val) {
  console.log("Reading: "+val);
});
