MPU6050 connection failed

Mtn · April 15, 2016

Hello there,
I will do.( http://www.instructables.com/id/Gyro-Stabilizer-W-Arduino-and-Servo/?ALLSTEPS )But I'll do it with an Arduino UNO. But I'm glad to help if I have some problems. Thank you for your attention.

Given the error:

Hi, I'm Stefano and this is my first request on this forum.

I'm using the I2Clib with Arduino UNO (IDE 1.6.9).

I have a little board named MPU-92/65 on GY6500 with the following pins:

Vcc, GND, SCL, SDA, EDA, ECL, AD0, INT, NCS, Fsync

I have installed i2Clib and I am able to retrieve raw values (both acc. and gyro seem to work fine) on address 0x68 (AD0 low to arduino GND)

My only problem is that I get "MPU6050 Connection failed" when the MPU6050_raw calls accelgyro.testConnection().

In fact, I print on serial the result of accelgyro.getDeviceID() and it is 56...decimal number for 38 in hexa....

But afterwards values are printed (they change with orientation of board...it seems definitely working....).

the board can be found at http://www.robotpark.com/GY-521-MPU6050-6-Axis-Gyroscope-Acceleration-Sensor-Module

Should I be worried that the connection test failed (values not reliable) or should I just ignore it?

Thank you in advance

Stefano

Hello guys

i am new to arduino i am using the pro mini with the MPU 6050

the code i am using is the raw data from https://playground.arduino.cc/Main/MPU-6050#short first i was facing the same problem the values on the serial monitor were all -1

i tried pull up resistors on SCL and SDA but didn;t work

then to connect AD0 to GND aslo the same but when i connect AD0 to Vcc (5V) it worked but not completely

i am getting values and they are changing but i am getting gibberish characters on the serial monitor as well

Any suggestions to fix the problem

Thanks in advance
