MPU 6050 on arduino not working

Other Hardware Sensors
1

So i am trying to get this new 6dof gyro and acceletomiter working, but i have tried everything, and it is not working. my final stop was the i2cdev library buy jeff, and it is even worse. I does not print normal caracters i get this(using his MPU6050_DMP6 example sketch on the uno)

    ÛðهT·DWá÷

and when i enter a letter this happens

    ÛðهT·DWá÷MÌÖk†–O`nþ

when i tried using his MPU6050_raw example this happens

    ààüàààààü¨¬ ±	-!-14¤¥5%…µ$%¥¡0 ´¥Ç%µ!0 4¤!¡!%5´¥

and it keeps printing nonstop.

so i decided to try the examples from the arduino webside on the mpu6050 i wont put the code here since it is to long but here is a link to it (Arduino Playground - MPU-6050 it is the last example down roughly 900 lines)
here is what i got:

as you can see when i move it the numbers become incredibly huge(at least the temperature is right). so i then decided to give the other example roughly 40 lines long on the same page. and my out come was as strange:

[code]    AcX = -682 | AcY = 2178 | AcZ = 17698 | Tmp = 27.55 | GyX = 473 | GyY = 234 | GyZ = -219
    AcX = -598 | AcY = 2224 | AcZ = 17580 | Tmp = 27.57 | GyX = 550 | GyY = -59 | GyZ = -680
    AcX = -756 | AcY = 2196 | AcZ = 17680 | Tmp = 27.57 | GyX = 375 | GyY = 272 | GyZ = -164
    AcX = 5578 | AcY = 13118 | AcZ = 13424 | Tmp = 27.57 | GyX = 32767 | GyY = -13348 | GyZ = -1000
    AcX = 1846 | AcY = 14718 | AcZ = 7596 | Tmp = 27.55 | GyX = 875 | GyY = 362 | GyZ = -32
    AcX = 2216 | AcY = 14504 | AcZ = 6930 | Tmp = 27.57 | GyX = 630 | GyY = 800 | GyZ = -1125
    AcX = 2390 | AcY = 14968 | AcZ = 7338 | Tmp = 27.57 | GyX = 568 | GyY = 241 | GyZ = -92
    AcX = 2338 | AcY = 14928 | AcZ = 7486 | Tmp = 27.54 | GyX = 561 | GyY = 158 | GyZ = -396
    AcX = 2698 | AcY = 15038 | AcZ = 7466 | Tmp = 27.55 | GyX = 1231 | GyY = 341 | GyZ = -252
    AcX = 7560 | AcY = 12958 | AcZ = 11980 | Tmp = 27.55 | GyX = -32768 | GyY = 19048 | GyZ = 7243
    AcX = -106 | AcY = 876 | AcZ = 16868 | Tmp = 27.53 | GyX = 890 | GyY = -442 | GyZ = -1959
    AcX = -114 | AcY = 1390 | AcZ = 17586 | Tmp = 27.55 | GyX = 1534 | GyY = -281 | GyZ = -665

it is the same issue as before i get really huge and odd numbers. i don't think this is deg/s nor deg/minute. can anyone assist?[/code]

The strange characters are because a different baudrate is used. In the example is something like this :

Serial.begin(115200);

When the baudrate is set to 115200, you also have to set the serial monitor to that baudrate.

The numbers for the accelerator and gyro are indeed huge and fluctuating. Which breakout board of the MPU-6050 and which Arduino board are you using ?

The MPU-6050 has undocumented registers, I hope you didn't write to those. If you keep the MPU-6050 really very still, the numbers should not change that much. An example of the numbers are also on that page in the Playground : Arduino Playground - MPU-6050
