Hi guys,
I want to apologise in advance for my bad english.
I downloaded the Arduino AHRS code and I wanted to see the data in 3D real time so i downloaded the files “Python 2.7 " , “pywin32”, “pyserial” and “VPython” all for x32 system as recommended(if you scroll down the posted URL adress you will see them)and i tried to run the “MinIMU-9-test.py” file atached in Arduino AHRS folder.After installing everything and running the “MinIMU-9-test.py” I received the result in text form (the window on the right of the atached picture),but the 2 windows on the left wich should show the data in 3d don’t respond and stays gray.I am running a Windows 7 Ultimate (x64) .I tried to reinstall the needed programs with compatibility mode(“with run as administrator” and " Run with Windows XP Service Pack 2” options selected) but its still not working.Does someone have an idea how to fix this.Appreciate your time.Cheers.

This is a test/3D visualization program for the Pololu MinIMU-9 + Arduino
AHRS, based on “Test for Razor 9DOF IMU” by Jose Julio, copyright 2009.
This script needs VPython, pyserial and pywin modules
First Install Python 2.6.4 (Python 2.7 also works)
Install pywin from http://sourceforge.net/projects/pywin32/
Install pyserial from http://sourceforge.net/projects/pyserial/files/
Install VPython from http://vpython.org/contents/download_windows.html
