MPUTeapot plane idle about i2cdevlib

[Odutna]

Hi,

I have the same issue. I tried the FreeIMU Lib, written by Fabio Varesano
and based on i2cdevlib, and all works fine.
I'm still trying to figure out if I did something wrong, and what ...

I'm trying MPUTeapot with Arduino UNO, a MPU6050.
In processing, when I run the sketch I'm able to see the ypr values but
the image of the plane is always idle.
I used the latest version of your sketches, the latest toxiclibs library,
Arduino 1.0.5 IDE and Processing 2.1 on several PCs and OS.
The MPU6050 is a GY-521.

Hello,

If you can see YPR values, then the Arduino sketch is not outputting the correct format. For the MPUTeapot demo to work, you have to comment out all of the OUTPUT #define's except for the TEAPOT one, which is a special binary format. The MPUTeapot example was built to mimic the format used by InvenSense's own Teapot demo application and uses this binary packet output.

Thank you very much, it works like a charm!

Hi
I'm using MPUTeapot and Teensy 3.1 based on Arduino software. I can see the raw values and Quaternion on Arduino. However, when I run the MPUTeapot it gives me the following error:
"The constructor Quaternion(float, float, float, float) is not visible"
Please help me with this.

Thanks.

Hi,

Have you add the library for Quaternion which I mean *.h like helper_3dmath.h ?

No! where can I find this Quaternion library?

[jrowberg]

The Quaternion library used in the Processing sketch comes from ToxicLibs:

• http://toxiclibs.org/downloads/

The code comment block at the top of MPUTeapot.pde points to this:

// NOTE: requires ToxicLibs to be installed in order to run properly.
// 1. Download from http://toxiclibs.org/downloads
// 2. Extract into [userdir]/Processing/libraries
//    (location may be different on Mac/Linux)
// 3. Run and bask in awesomeness
