Hi I'm having problem uploading the code to arduino uno... the error below appears everytime...
can someone help to rectify this issue.. thanx

Code:

// I2C device class (I2Cdev) demonstration Arduino sketch for MPU6050 class
// 10/7/2011 by Jeff Rowberg <jeff@rowberg.net>
// Updates should (hopefully) always be available at https://github.com/jrowberg/i2cdevlib
//
// Changelog:
//     2011-10-07 - initial release

[Reply #1 on:]

You've copied the code from a website, and it has illegal characters in it.
I'd copy it into an editor like Notepad++, and use that to sniff out and eliminate the illegal characters.

[Reply #2 on:]

Can you please specify the illegal characters...
i have already converted the files to ANSI Encoding... after copying from the website...it doesn't seem to work.

[Reply #3 on:]

I had that happen with code I copied from a website and ended up having to go into a hex editor to get rid of it. When you look in the hex editor you will see it right away as the first byte.

[Reply #4 on:]

The code you posted above does not compile, for me, because I don't have any of the libraries it includes. But, it does not generate any messages about stray \ characters. So, the issue is in the libraries, not the sketch.

[Reply #5 on:]

Can you please tell how to add this library.. to resolve this issue... i created a the missing library folders in \Documents\Arduino\libraries folder.. n copied the files to it, it doesn't seem to work..

https://github.com/jrowberg/i2cdevlib/tree/master/Arduino/MPU6050
this is the original site i got the code from...

[Reply #6 on:]

Use this link instead and click on "ZIP"
https://github.com/jrowberg/i2cdevlib

This will actually download all the files instead trying to copy and paste them which is what is causing your problem.

[Reply #7 on:]

Have I ever mentioned that I hate github. That has got to be the crappiest excuse for a web interface in the history of the internet. If you click the Code link, you can download a zip file.

Doing that, extracting the libraries, and pasting your code into the IDE again results in just one "error" message:

Binary sketch size: 6,330 bytes (of a 30,720 byte maximum)

Thank you very much guys... it's finally working..
