Linear Acceleration Readings Are Way Off

Hello!

I have installed Jeff Rowberg's i2cdevlib library for Arduno which I can use for my MPU-6050 to make it interact with Arduino.

However, I have an odd problem with one of its functions.

It's got a function to turn the accelerometer & gyroscope readings into linear acceleration. This is the definition of the function:

uint8_t MPU6050::dmpGetLinearAccel(VectorInt16 *v, VectorInt16 *vRaw, VectorFloat *gravity) {

   // get rid of the gravity component (+1g = +8192 in standard DMP FIFO packet, sensitivity is 2g)

   v -> x = vRaw -> x - gravity -> x*8192;

   v -> y = vRaw -> y - gravity -> y*8192;

   v -> z = vRaw -> z - gravity -> z*8192;

   return 0;

}

However, whenever the function is called in the example code:

            // display real acceleration, adjusted to remove gravity

           mpu.dmpGetQuaternion(&q, fifoBuffer);

           mpu.dmpGetAccel(&aa, fifoBuffer);

           mpu.dmpGetGravity(&gravity, &q);

           mpu.dmpGetLinearAccel(&aaReal, &aa, &gravity);

           Serial.print("arealt");

           Serial.print(aaReal.x);

           Serial.print("t");

           Serial.print(aaReal.y);

           Serial.print("t");

           Serial.println(aaReal.z);

I get values way off, when I'm not even moving my MPU-6050!

These are a few of the values I get:

areal	-473	423	-425

areal	-460	400	-450

areal -471	522	-458

areal -322	276	-582

Do you know how I can fix this?
Thanks!
