Hey guys and gals,
I'm having trouble getting data from both of my sensors at the same time. The GPS works when wired by itself, and the BNO055 works by itself, but when I try to use them at the same time, I don't get anything from the BNO055. 
I'm using an Arduino Duemilanove and Adafruit's Ultimate GPS along with the BNO055 Multi-purpose sensor. I've wired both up just like the diagrams here and here (except the sensors are on a breadboard an share power coming from the Arduino).
This is the code I'm using using the johnny-five library:
const five = require('johnny-five');
const board = new five.Board();
board.on('ready', () => {
var layout = `
Board layout:
+----------+
| *| RST PITCH ROLL HEADING
ADR |* *| SCL
INT |* *| SDA ^ /->
PS1 |* *| GND | |
PS0 |* *| 3VO Y Z--> \-X
| *| VIN
+----------+
`;
console.log(layout);
var imu = new five.IMU({
controller: "BNO055"
});
imu.on("change", function() {
console.log("Thermometer");
console.log(" celsius : ", this.thermometer.celsius);
console.log(" fahrenheit : ", this.thermometer.fahrenheit);
console.log(" kelvin : ", this.thermometer.kelvin);
console.log("--------------------------------------");
console.log("Accelerometer");
console.log(" x : ", this.accelerometer.x);
console.log(" y : ", this.accelerometer.y);
console.log(" z : ", this.accelerometer.z);
console.log(" pitch : ", this.accelerometer.pitch);
console.log(" roll : ", this.accelerometer.roll);
console.log(" acceleration : ", this.accelerometer.acceleration);
console.log(" inclination : ", this.accelerometer.inclination);
console.log(" orientation : ", this.accelerometer.orientation);
console.log("--------------------------------------");
console.log("Gyroscope");
console.log(" x : ", this.gyro.x);
console.log(" y : ", this.gyro.y);
console.log(" z : ", this.gyro.z);
console.log(" pitch : ", this.gyro.pitch);
console.log(" roll : ", this.gyro.roll);
console.log(" yaw : ", this.gyro.yaw);
console.log(" rate : ", this.gyro.rate);
console.log(" isCalibrated : ", this.gyro.isCalibrated);
console.log("--------------------------------------");
console.log("magnetometer");
console.log(" heading : ", Math.floor(this.magnetometer.heading));
console.log(" bearing : ", this.magnetometer.bearing.name);
console.log("--------------------------------------");
});
/*
* This is the simplest initialization
* We assume SW_SERIAL0 for the port

var gps = new five.GPS({
breakout: "ADAFRUIT_ULTIMATE_GPS",
pins: {
rx: 11,
tx: 10,
}
});
// If latitude, longitude, course or speed change log it
gps.on("change", function() {
console.log("position");
console.log(" latitude : ", this.latitude);
console.log(" longitude : ", this.longitude);
console.log("--------------------------------------");
