For anyone using the MPU-6050 or MPU-9150 with I2Cdevlib, there is an official support forum for those devices when used with that library now available here:

http://www.i2cdevlib.com/forums/forum/2-mpu-6050-6-axis-accelerometergyroscope-invensense

It's a little easier to work with an endless comment threads here, and more open than the InvenSense forums (no draconian "no reverse-engineering allowed" terms of service). There are already answers up there to some of the questions here.

Documents MPU-6050 datasheet link does not work!

Datasheet (Revision 3.4) and MPU-6050 Register Map and Descriptions documents can be obtained from: http://www.invensense.com/products/motion-tracking/6-axis/mpu-6050/

Got it to work just fine with my Uno, but I am having trouble getting it to work with the Pro Micro and/or Leonardo. From what I understand is that on the Uno the SCL and SDA pins are located on A5 and A4 whereas on the Leonardo it should be on D2 and D3 (the digital pins 2 and 3, not the atmega32u4 pins). The sample sketch for reading raw data uploads successfully, however, upon turning on the serial monitor, its completely blank. Does anyone have any ideas on how to get this to work on the Pro Micro or the Leonardo? Thank you!

Is the operation of this thing still locked up tight, away from hobbyist access?

I recall something about the whole "capable of processing complex 9-axis MotionFusion algorithms" meaning "capable if you're a big company and we decide to share the documentation with you".

And hobbyists were just able to get the raw sensor data (still neat) but not access the nice algorithms? Has that been remedied? Is this a magic IMU in a chip now? (minus compass)

Because if those algorithms are still not something we can use, I think Sparkfun needs to mention that in the description.

My friends and I used this to create a cube that acted as a Bluetooth remote control. It worked really well.

We used it with mbed by using a ported Arduino lib. We actually made a tutorial for anyone wanting to do something similar, check it out here!

http://nordicsemiconductor.github.io/puck/tutorials/cube.html

I just wanted to say that the MPU9150 works great if you just want access to raw accelerometer, gyroscope, and magnetometer measurements to implement your own motion fusion algorithm on a micro controller. However, one of the main appeals of this chip and its sister, the MPU6050, is on-board data fusion. In short, Invensense (reluctantly) provided official support for on-board data fusion through their MotionDriver 5.1 library. The library is available through their developer corner, which is accessible through a free account. This library has since been (ported to be used on Arduino Microprocessors) [https://github.com/richards-tech/MPU9150Lib/tree/master/libraries/MotionDriver] .

I received an e-mail from Invensense on July 9th saying that they have released their MotionDriver 6.0, capable of doing 9DOF sensor fusion. I was under the impression that the library enabled on-board 9DOF sensor fusion. However, I came to the conclusion that the 6DOF motion fusion was handled on the chip, and fused with magnetometer sensor data using a pre-compiled library provided in the MotionDriver 6.0 software. This library only works with TI MSP430 and ARM Cortex Chips since it is pre-compiled. In short, the 9DOF motion fusion is handled with the same approach that Pansenti (now Richards-Tech) took to enable 9DOF sensor fusion through his (MPU9150 Arduino Library)[ https://github.com/richards-tech/MPU9150Lib] but with probably a different motion fusion algorithm.

Wow, the I2Cdevlib repository made it into the Documents list! I'm honored, really. However, instead of the main class library parent source folder, you might want to point to the main MPU-6050 device page here:

http://www.i2cdevlib.com/devices/mpu6050

I guess they are both good links, but the device page has much more information including an interactive register map, highly detailed I2C capture analysis of InvenSense eval/ARM board DMP traffic, and some very, very rudimentary reverse-engineered info on DMP registers and usage. More documentation may come as some encouraging and ongoing talks with InvenSense continue...they appear to be legitimately trying to satisfy the OSHW community. I'm hopeful anyway.

EDIT: adding link to the new I2Cdevlib support forum:

http://www.i2cdevlib.com/forums/forum/2-mpu-6050-6-axis-accelerometergyroscope-invensense/

The silkscreen of the Z axis looks incorrect. When looking the board from above, the Z axis is pointing the face of the viewer. Following the right hand rule, a positive rotation is a counter clock wise one.

Note that most of the coolest features of this device are only available having access to the DMP documentation. Since currently such documentation is not available from Invensense very few of such advanced things can be implemented with the MPU6050.

International customers beware of excruciatingly long shipping delays with spark fun for this product. I ordered this on June 12th, now June 20th, product still hasn’t shipped!! No indication from SF when it will happen either. I bought this same item in 2013, turn-around was 1 day, including being sent and returning the questionnaire about nefarious use.

This time SF took days before they even sent the questionnaire. I feel like I’ve wasted a bunch of money on priority shipping to have SF sit on their hands for days on end. Never mind the delays in using it!!

Not impressed with SF :-(

I am trying to create a MPU-6050U that can wirelessly transmit to a DAQ. Any ideas of what I should do or what I should do?

Hai, may u email me purchase order for the product SparkFun Triple Axis Accelerometer and Gyro Breakout - MPU-6050

Is there a basic function that I can simply use to find how much the gyroscope has rotated?

I can't believe the price SF wants for this; equivalent products are available all over the web for $5-12.

Hi I am new to using Sen 11028, Can any one show me the connection or wiring diagram for sen 11028 with Arduino. I have currently connected the MPU 6050 to Arduino using a bread board.

I think for this device I'm going to have to insist on a board with four mounting holes :-)

How would I wire up this board to an Arduino and use it as if it was the 6 DoF board? My project only requires me to use 6 DoF but this board is labeled differently so I'm not sure how to connect it. Thanks!

Lol. it took me some time to figure out, VIO needs to be connected to VDD for the gadget to work,

Hey guys, I'm having difficulty communicating with the MPU-6050 through I2C lines. I did some troubleshooting and it looks like my SDA is directly connected to VDD with about 86 ohms of resistance. I've removed the 4.7k pull up resistor connected to SDA and the problem persists. Has anyone else had this kind of problem or is this a faulty breakout board?

Hi, i'm using mpu6050 together with mbed NXP LPC1768, the connection is almost thesame with that of arduino. mbed mpu6050 Vout vdd GND GND P9 SDA P10 SCL then the Vio is connected to Vdd on thesame mpu6050. i was using pull up resistor of about 10k before but there was a fault somewhere which i couldn't trace,my teraterm was writing mpu6050 connection failed and my device Id gave me 0,though i did some soldering and it worked before even my code works very fine. I've tried continuity test and my connection is continous.AD0 is connected to ground.please can you suggest what could have happened to my imu?my mbed works well but does not see the 6050 but i have been using it before.

Please excuse the simplicity of my question, but I'm new here and have no experience with circuits. How do I connect this board to a computer and what language could I use to code programs using it in? I'm trying to make a camera with a wide angle input but narrow output that corrects for changes in angle and position for a long term school project. I have experience coding in java. Any help is greatly appreciated.

I need help. I am trying to pick out an IMU, but i don't know which one to get. What I need is something that can figure out where it is based on where it started, in an area no more than 1000 sq feet. Help would be appreciated.

Hello Jeff, hello guys..

i have a problem with the "MPU6050_DMP6" sketch from GitHub that Jeff has posted...and just with that.. (https://github.com/jrowberg/i2cdevlib/blob/master/Arduino/MPU6050/Examples/MPU6050_DMP6/MPU6050_DMP6.ino).

I have an Arduino MEGA 2560 and i've followed all the instructions for wiring and all as well as looking at almost all the posts of this and Arduino's forum for, but haven't really found a solution:

so basically, once finished uploading the sketch "MPU6050_DMP6, i see on the Arduino Mega the TX led going ON for about 1 second, and then stopping any transmission. On the Serial Monitor, instead, i see a short message like "Myÿ£eæÇô¸".

The "RAW" example sketch works giving me some weird digit values on the Serial Monitor like: $°°gŵ 40ű°Åµ0¥∞ű°§40ű°•Ì §%Å°°Åµ†4%°1$.....and goes on forever

the "I2CScanner.pde" sketch from Tod E. Kurt (http://todbot.com/blog/) something like: òö(åà÷sa÷sà÷sL»÷sLà÷sà÷s(à÷sL»÷sLà÷såà÷s....

while instead the example sketch from Krodal (http://playground.arduino.cc/Main/MPU-6050?action=sourceblock&num=1) is actually working perfectly:

Inyro, error = 0 accel x,y,z: 304, -532, 17572 temperature: 30.153 degrees Celsius gyro x,y,z : -169, -49, 204, l, temp and gyro, error = 0 accel x,y,z: 304, -532, 17572 temperature: 30.153 degrees Celsius gyro x,y,z : -169, -49, 204, InvenSense MPU-6050 June 2012 WHO_AM_I : 68, error = 0 PWR_MGMT_1 : 0, error = 0

and on and on with correct the data readings.....

as well as working are all the patches from this page of the forum: http://forum.arduino.cc/index.php?PHPSESSID=khqj3vmde300r2lokg3aakuh37&topic=103408.15

I'm sorry but i really cannot figure out what is the problem, i've tried to #include the "Wire.h",

define whatever MPU6050_ACCEL_XOUT_H 0x3B and so on, but the Main patch gives me always

those unreadable values on the Serial Monitor..

Do you maybe have a clue on what is wrong?

thanx a lot!

Federico

If some one is interested and wants a simple implementation of MPU6050, they can also have a look at this simple Library, http://hobbylogs.me.pn/?p=47 It also explains angle calculation combining gyroscope and accelerometer measurements to avoid drift problem.

I need an help from someone who is bettere than me. Can I use this accellerometer for Arduino 2?

Hi! I want to connect my arduino uno to two mpu 6050 in order to canculate the relative angles and velocity, Did some one already made something similar and knows how to connect the 2 mpu 6050 ? Also we would like to be able to visualize our data in a graph, is there a script we can use??

Thank you!

Hi All: Is there any way to get either the delta t (time between measurements) or a time stamp for each data set (ie: XYZ gyro, XYZ Accel reading) out of the DMP as I need it for my application.

Thanks, Dave

Can someone tell me the dimensions(mm or in) of the breakout board(L x W x H)? or tell me where I can easily obtain it without buying one and measuring myself.

What are the dimensions (mm or in) of the breakout board?

Question: What are the dimensions(mm or in) of the breakout board? I need to check if it will fit into my prototype before I buy it and I need a better estimate than a picture with a quarter

Hi,

I have been searching all over but cannot find a simple step-by-step guide for how to hook it up to an Arduino Uno and a sample program that works. I've tried using the included examples to no effect (loads of errors) and this one (http://playground.arduino.cc/Main/MPU-6050#sketch) compiles but doesn't do anything... Sorry for the noob-ishness! Would really appreciate any tips or help!

Hi just got the " MotionFusion" working on arduno uno (how on earth did Jef work out the code?? well done! I have coded for a quad copter using raw data and using 3 indipendant pid controllers Just a small thing roll and pitch are under reported (90 degs tilt reports only 65 degs) yaw looks ok i am thinking accelerometer calibration may be the problem raw readings are a bit out
how do we get offsets back into the " MotionFusion" part of the coding? I am in well above my head on this one can any one sugest an answer?? Thanks Tim Painter

Hi guys, i need to make a project that just will work when a person is moving, like walking arounf the streets. Can u help me? I'm really confussed, im 18 and i dont know much about accelerometer tanks

According to the I2Cdevlib link you provide it says: "Due to the lack of good publicly available documentation about the inner workings of this device, all DMP-related information has been reverse-engineered from I2C signal analysis correlated against the company-provided Embedded MotionApps software "

It goes on to say: "Currently, the source code available will only provide basic device configuration and raw accel/gryo readings (which is certainly useful, but missing the main selling point of the MPU-6000 series, which is the device-powered motion processing ability)."

What the heck...

Hi, this is probably a noobie question but I was wondering why my code didn't work. I'm using the MPU6050.ino code to implement a kalman filter on the digital IMU. The ino file uses i2cWrite and i2cRead but my program will say error. I2cWrite and i2cRead weren't defined. I have the and files. I

I was wondering in which file (header?) is ic2Write defined? Also, I can't find the location of my file called by the wire.h file.

es posible controlar el mpu 6050 por medio de una fpga (spartan 3e)? como se podria hacer?

hola!

compre un sensor 11028 mpu 6050 y estoy empezando a trabajar, soy novato en este tipo de comunicación i2c, ademas tengo una nexys 2 de digillent (incluye una spartan 3e). en el debate he visto mucha información relacionada con arduino y pic.

mi pregunta es: es posible controlar el sensor por medio de una fpga? si es posible, me podrían colaborar con el código, tutorial, o manera para crear el código que me permita manipular el sensor. muchas gracias a todos, espero me puedan colaborar

Forgive my ignorance, but can anyone give comparison between the positional accuracy of 6 axis (without magneto) vs 9 axis? I plan to built motion capture glove (hand tracking), but I can’t quite grasp whether absolute yaw (i.e magnetometer) is indeed essential for hand tracking. I’m going to use it for gripping VR objects. Thanks

Alright so I'm totally new to all this, so please forgive me if this is a dumb question. How well would this work with something like this... http://nathan.chantrell.net/tinytx-wireless-sensor/#comment-140654 ? I'm wanting to create multiple sensors that would all relay data back to a base station to track a person' s movement. Thanks!

Hi I was wondering what the sensitivity is for the gyroscope in Jeff Rowberg's example code. Is it 131 LSB/°/s?. And for the accelerometer is it 16384 LSB/g? Thanks.

Where can I find doc to chain HMC6352 and MPU6050? How to read the datas with Arduino? Any help will be greatly appreciated!

I am trying to set the sampling rate for the accelerometer and the gyroscope.

From the register map (http://www.invensense.com/mems/gyro/documents/RM-MPU-9150A-00.pdf), (page 11 of 60):

Register 25 – Sample Rate Divider SMPRT_DIV

The Sample Rate is generated by dividing the gyroscope output rate by SMPLRT_DIV: Sample Rate = Gyroscope Output Rate / (1 + SMPLRT_DIV) where Gyroscope Output Rate = 8kHz when the DLPF is disabled (DLPF_CFG = 0 or 7), and 1kHz when the DLPF is enabled (see Register 26). The accelerometer output rate is 1kHz. This means that for a Sample Rate greater than 1kHz, the same accelerometer sample may be output to the FIFO, DMP, and sensor registers more than once.

In my understanding, if the DLPF (Digital Low Pass Filter) is enabled then both the gyroscope and the accelerometer sample at 1kHz and setting a value of say 4 in register 25 will make the sample rate: 1kHz / (1+4) = 200Hz for BOTH the accelerometer and the gyroscope. Is that correct? Does enabling the DLPF not affect the sampling rate of the accelerometer as it does for the gyroscope

I want to eventually design a digital filter by converting a continuous time filter (using conventional Bode plot techniques) and need to know the sampling rate for the conversion.

I have an Adafruit SD logger shield which uses the SDA and SDL pins. How can I connect the MPU-6050 to the shield and have it use the SDA and SDL pins for both the shield and the MPU-6050 breakout. I'm really stuck here. The shield does not work (as well as the MPU-6050) when I connect to the SDA and SCL pins.

Can I programmatically change things?

Much appreciated!

I hope someone can help me out. I'm using the MPU6050 along with an Arduino UNO and Jeff Rowberg's library and codes. The connections are made properly and the IMU works fine for some time. However, after a period of time, that usually goes from around 30 seconds to some minutes. It stops sending values to Arduino. I've already checked the code and there's no loop where it could possibly be stuck (such as not resetting the FIFO). Thus my only guess is that the IMU just shuts down (it's the same effect as pulling the Vdd cable out from Arduino) and won't work again unless I reset Arduino.

Have anyone had a similar problem or have any guess of what can be happening.

Thanks a lot!

hi, I have this MPU6050, but I have a problem with it, it reads 0 from all registers except 0x75 register it gives 0x68, even when I set the 0x6B register to 0x01 nothing changes.

Hi! I'm using this sensor with my arduino mega and i have some weird problem:

The connections between arduino and IMU are: VDD - Arduino 3.3v GND - Arduino GND INT - leave unconnected FSYNC - leave unconnected SCL - Arduino SCL (dedicated pin 21) SDA - Arduino SDA (dedicated pin 20) VIO - Arduino 3.3v CLK - leave unconnected ASCL - leave unconnected ASDA - leave unconnected

When I run the MPU6050_Raw sketch it says connection failed. I try to connect de VDD and VIO pins to 5V and it works fine. I use this connection only once and for 2-3 minutes to not damage the chip. Should i use the sensor with this connection to 5V pin? Anyone have suggestions?

Thanks!

For anyone that is struggling to get this sensor to work with an Arduino Leonardo using the libraries provided the example code link, I was able to get it to work by doing the following:

First, the Leonardo I2C interface is detailed here: http://arduino.cc/en/Main/arduinoBoardLeonardo SDA -> Digital Pin 2 SCL -> Digital Pin 3

Second, the Leonardo interrupt setup is detailed here: http://arduino.cc/en/Reference/AttachInterrupt The DMP6_test is setup to use interrupt 0 which is Digital Pin 2 on the Leonardo. I changed the line:

attachInterrupt(0, dmpDataReady, RISING);

to:

attachInterrupt(4, dmpDataReady, RISING);

And connected the interrupt to Digital pin 7.

The DMP6_test and Processing sketch now works like a charm! I hope this helps anyone else that was struggling with the Leonardo setup.

Thanks to Jeff Rowberg for your great work and those usefull examples.

The "MPU6050_raw" example is working fine for me. But the "MPU6050_DMP6" is not, I'm seriously thinking that my INTpin is not connected between MPU6050 & Atmega. (I'm using a all-in-one Drotek flight controller)

Is there a way to make the MPUteapot work without the INT pin connected ? Is it possible to change the wiring of the INT to another Arduino PIN (I mean, not the digital PIN2) ?

I've just started with Arduino and sensors and I am not experienced with any of this things.

For a university project we bough an Arduino UNO and an MPU-6050 sensor. I started connecting the two as follows: MPU UNO - VCC = 3.3V - GND = GND - INT = Digital Pin 2 - SCL = Analog Pin 5 (without resistor!) - SDA = Analog Pin 4 (without resistor!) - VIO = 3.3V

FSYNC, CLK, ASCL and ASDA unconnected.

We used the I2cdevlib libraries and examples given on the sparkfun site (https://github.com/jrowberg/i2cdevlib). We tried a test and the sensor worked fine and gave signals for a while. We shook it a bit to see if the values changed and it suddenly stopped responding and gave only 0's as output. Since then, we've been unable to get any response form the sensor. We did an i2c connection test and it responded correctly (connection found on 0x68), yet the sensor test says the device is not connected.

We later discovered that for the UNO R3 there are dedicated pins for SCL and SDA. Furthermore, the two analog pins are used as input for the sensor instead of output. Being the Arduino UNO a 5V system, did we fry the sensor by sending an excessivly high input voltage? How is it possible that it worked fine for 5sec before crashing? Could we have broken the sensor by shaking it?

Thanks for taking the time to read this, we could really use some help

Hi everyone,

I started working on the MPU6050 with a mbed NXP LCP1768 this week. I have the following connections : VDD -> mbed's 3.3V GND -> mbed's GND SCL -> mbed's SCL SDA -> mbed's SDA VIO -> mbed's 3.3V

I am using the libraries adapted from Arduino by Szymon Gaertig.

I always get a failed connection, does anyone have had this problem ?

Regards, Maxime

I just got this IMU working with my Arduino Uno R3. Does anyone have a Processing (or other graphical) sketch/program that can visually depict the sensor information coming off the serial port? I am using the Pansenti implementation -- not the code linked above. Thanks!

Hi all,

I am working on a project where I am using the mpu6050 to collect data (this works great), and depending on the status of an external sensor value (a simple switch) the mpu6050 should be ignored/powered down/go to sleep and some other code should be executed.

The question is therefore how can I best tell the mpu6050 to stop sending data to my atmega? hope you can help me out!

Best regards,

Is it possible to assign 3 of these different I2C addresses, then have one Arduino read the values of those 3 boards to compare?

I see that its address is 0x68 by default and can be changed to 0x69 by pulling AD0 high, but what if I need to read a third board too?

For Raspberry Pi users: To connect and test the board using the "i2cdetect" tool, you should connect the following pins:

hi jeff! I have a mpu6050. I want to use for myquadcopter.I use PIC16F877 as process.But I dont know how to use this sensor.which pin connect to PIC16F877.is the INT pin used? can you tell me which pin connect to where? wait your answer!!

Hi guys, I'm using this with my Arduino Mega with no logic conversion and for some reason about one in every 20 readings from the gyro are wildly spiking, and giving a completely random reading. Anyone know why this is the case? Im using the MPU6050_raw sketch.

Why is it that I get a weird tick every now and then when I use the MPU6050_DMP6 example sketch? What I mean is that the accelerometer data runs normally and every few seconds, it jumps from a normal value to an extreme value.. without any interaction. I found another sketch that pulls the data without going through the MPU and that works, but I really would like to use the DMP processing like gravity removal.. how to fix this?

MPU6050_RAW and MPU6050_DMP6 sketches from github output to serial monitor as non-readable... so how do we see sensor data?

I have wired sensor as Jeff posted

i2c scanner, is good, serial monitor outputs, "I2C device found at address 0x68 !"

for my science proj tomorrow, any help please! Theo

i2c scanner, is good, serial monitor outputs, "I2C device found at address 0x68 !"

for my science proj tomorrow, any help please! Theo

This kind of thing is very new to me so please excuse my ignorance. I am attempting to get this working with an atmega328, with this breakout running at 3.3v and the atmega chip running at 5v. I am a little worried about the need to level shift the I2C bus. I notice there are a couple of 10k pull up resistors on the schematic from SCL and SDA to VCC (3.3v) which I understand is a solution to making a 5v microcontroller handle the lower voltage I2C signal? Just wondering whether this will work simply by connecting the two together or whether I should implement something more concrete like the MOSFET type circuit I have seen around. Also does anybody know if the start-up procedures mentioned in the MPU6050 datasheet are crucial? I only just noticed them!

Hi Everyone,

I hope this is a fairly simple question to answer as I'm trying to understand how the rotation matrix of the MPU6050 works...

I've got the sensor attached to a set of headphones and essentially what data I need to gather is the rotation data from when they person turns their head (around the Y axis). I know the MPU6050 outputs a 4x4 matrix so I guess what I need to know is what column/row etc that I'm looking at drawing data from.

I hope this makes sense. Any help would be greatly appreciated!

I currently have a problem when using WHO AM I the mpu6050 returns the value 0x68 but when I read the gyro and accelerometer I only get zero for all sensor the device is not in sleep or wake mode. Could it be due to vdd not being present I have checked the board but there my be an open circuit between the IC and PCB has anybody had this problem.

Sir, I am interfacing the mpu 6050 to an ARM LPC2148 board as per the connections we are connecting VDD+VIO to 3.3v GND to GND SCL -> ARM's SCL SDA -> ARM's SDA

we can read registers without any problem but cannot write into them :( anything needs to be specific while doing the write operation like making the VIO low? something like that?

Need a response urgently already running late on submission :(

thanks in advance good Sirs :)

who to change gyro range mpu-6050 ? I think now it is set to 200 Deg/sec and I want to change it to 500 Deg/Sec. I found this in mpu6050.cpp file :

void MPU6050::initialize() { setClockSource(MPU6050_CLOCK_PLL_XGYRO); setFullScaleGyroRange(MPU6050_GYRO_FS_250); setFullScaleAccelRange(MPU6050_ACCEL_FS_2); setSleepEnabled(false); // thanks to Jack Elston for pointing this one out!

and I changed "setFullScaleGyroRange(MPU6050_GYRO_FS_250);" to "setFullScaleGyroRange(MPU6050_GYRO_FS_500);" and upload my arduino file again, but it seams that nothing has changed.

Does anyone know how to use two MPU-6050 simultaneously using the same Arduino board. I want to use multiple IMUs for my project to get minimal error for getting position. It seems impossible to change anything in the header files without messing it up! Any help would be much appreciated. Thanks. :)

Any chance that we will see a break-out for MPU-6000 as using SPI would be a plus. Thank you!

How would I go about connecting this MPU to a compass module such as a HMC6352 in order to get the output on an Arduino through the I2C bus with data like Ft/s, compass direction, and elevation information? Relatively new to the I2C bus, so any details appreciated. Thanks.

I'm a novice to Arduino and am trying to run the MPU 6050 for the first time, with the end goal being to test it with the invensense teapot/mouse demo. Right now, I'm just trying to get raw accelerometer and gyro data using the MPU. However, after 1 successful run, I've been getting the following error: 'DMP Initialization failed (code 1)'. Can anyone help?

Hi there! Can anyone tell to a newbie what VLOGIC does to I2C? Does it bring binary level logic to a higher voltage (VDD + VLOGIC) ? Thank you!

Why do you connect the exposed die pad to the board (at least if I can rely on the tCream layer of the Eagle file) when the data sheet specifically says not to do it (section 11.4.2 of the data sheet)? And as mentioned previously, the silkscreen for the Z axis is wrong: you have a cross when it should be a dot.

Eagle Library for MPU-9150 ( i draw to component and thats my first draw , if posible please test first ) http://web.deu.edu.tr/sbt/files/mpu9150.lbr

Any chance of you providing this board with the MPU-9150? I believe the pin out is the same...

Can we use this accelerometer breakout board to measure human walking velocity in one direction or we have to use IMU board( gyro & accelerometer together)?By integrating accelerometer readings we can get velocity. Are swing & stance phase of walking may create problem in velocity calculation? Is gyro is required?

Hi everybody!

I've bought two MPU-6050 evaluation boards and started using them with the code provided by Jeff Rowberg (btw really great work), namely the example to get raw data. what happens is that keeping the board still i get x,y,z acceleration values around 260, -92, 24216, respectively...when i turn the board so that gravity vector appears on x and y axes i see the value 16300 on each axis, which was what i expected since it corresponds to 1g. What i dont get is the 24216 on z axis. When i try the same code on the other board this doesnt happen and the values are just like expected.

Does anyone have any idea why this happens? Is one of my boards broken?

Thanks!

Does it require level shifting for the I2C line? Thanks, Rick

Anyone else getting a lot of gyro drift with a board sitting still?

Hello,

Ive owned this sensor for like 2-3 months now, but I dont really manage things to work out that fine. Ive used the "sketch for MPU6050 class using DMP (MotionApps v2.0)" and Ive been focusing on the yaw/pitch/roll values.

Problems:

• I have to wait for like 1 minute until all values are steady (one of em goes from like 1 degree to 16 degrees).

• If I try to make a servo dependent on the values I get fifooverflow and the values either gets screwd up or everything freezes.

I hope some1 could help me, and trust me Ive been searching for a solution for a long time without success.

Cheers

I connect to Pro micro(https://www.sparkfun.com/products/10999?) by MPU6050_raw code It not show value it show 0 0 0 ...

Help me

Hello everyone I've used the zip file from here: https://github.com/jrowberg/i2cdevlib/zipball/master and run the example MPU605_DMP6

Would someone tell me how do I get the x, y,z position?

thanks

The link for Example code is dead. Can anyone help please?

Great work with the libraries for MPU-6050! I am having some problem though with understanding the printout from the MPU6050_raw example. The result looks okay but when I move the hardware it feels like the accelerometer and gyro are mixed up. The accelerometer values are quite consistent relative to the angle of the board and the gyro values are changing rapidly whenever I move the board but returns quickly to old values.

Do I have a problem with my board or do I missunderstand the values?

Hi, the link for "Example code" is dead. Would anyone please tell me if there is another source for the code? thanks

Hello everyone! I,m from Russia and sorry for english at first! ) I use this accel&gyro who was bought on this site, and I have some problems with this board!!! Please Help! I connect SCL on the board to A5 and SDA to A4 inputs with pull-up resistors (10k or 4,7k) on Ardruino MEGA. GND to Ground & VDD to 3,3V. But I2C Scanner didn't find my MPU6050 board. What i do wrong????!!!!

Hi, you know where to buy MPU 9150 ? http://www.invensense.com/mems/gyro/mpu9150.html I found an AliExpress @ 10 USD but one must buy a lot because of DHL cost... http://www.aliexpress.com/store/product/100-New-INVENSENSE-MPU9150-MotionTracking-Sensor-MPU-9150/102034_558565991.html are many of you interested ? Can Sparkfun reease a breakout board with the MPU9150 sooner ? thanks Lotfi

what does the sync pin do?

Anyone know if this breakout is any good? Does it actually combine the data from the other sensors into the 6050? Also, is the 6050 programmed to automatically interface with the other sensors, or will I have to program the 6050 to make it interface?

EDIT: Got rid of errors, uploaded the code to the board, but i get no display about anything so i dont know if the code is working right. Isnt a screen suppose to pop up and give me values?

Hey, who bought all the boards?! - edit: already back in stock!

So, I noticed in that Invensense is trying to submit drivers for the MPU series for the Linux Kernel. I haven't been able to find the full source that they're trying to submit, but it does look like there are references to DMP firmware in what I could find. Also it appears that much of the MPU-6X50 commands are identical to the new MPU-9150.

Hi

For many days I look for examples of DMP data (Euler angles) to read with the Arduino. I find nothing! I hope there is someone who knows this? Thank you for your help.

best regards Hummer

When are these coming back in stock?

How does this compare w/ the http://www.sparkfun.com/products/10121 6DOF IMU? E.g. is all the fusion done on the 6050?

What would you like to see on the Invensense Developers Corner site? Honest question by those who make this chip. I've made my own opinions known. Like Jeff said, the company is aware of their mistakes and is looking to be more supportive in the future. If you've got suggestions, you could voice them here or email me.

The new chip with the magnetometer on board will be out soon. 2 weeks supposedly, but they (Invensense) often slip.

Where can I get an C code for the MPU-6050? I'm using ARM Cortex-M3 CPU core

Misleading statement in feature list. �I2C Digital-output of 6 or 9-axis MotionFusion data in rotation matrix, quaternion, Euler Angle, or raw data format

-- "when external magnetometer is connected" --> this should be added

Otherwise there is no way to get a rotation matrix/quaternion/complete set of Euler angles out of kust accelerometer+gyro data

The VLOGIC pin on the MPU6050 cannot be pulled just low. It needs to be pulled high with a capacitor to GND. The MPU6000 and 6050 have a difference of /CS and VLOGIC.

Pulling VLOGIC high is necessary as state in the datasheet. I may be wrong but pretty sure that needs to be high.

Hi Jeff, I just got the arduino UNO board and I connect the pins like VDD - Arduino 3.3v GND - Arduino GND INT - Arduino digital pin 2 FSYNC - leave unconnected SCL - Arduino SCL (dedicated pin or Analog 5) SDA - Arduino SDA (dedicated pin or Analog 4) VIO - Arduino 3.3v CLK - leave unconnected ASCL - leave unconnected ASDA - leave unconnected, then I type the c code in arduino SDK:
