bmp085's Issues

Failed to set address

using this code as test.js:

---

var BMP085 = require('bmp085'),
barometer = new BMP085({
'mode': 1,
'address': 0x77,
'device': '/dev/i2c-1'
});

barometer.read(function (data) {
console.log("Temperature:", data.temperature);
console.log("Pressure:", data.pressure);
});

---

results in this:

wire.setAddress(address);

The sensor is correctly recognized as it can be seen in:
