Much appreciated David!
So the 9150 code can be used also for the 6050? I am not familiar with that
sensor, but it sounds like it is the previous version of the 6150?
The ADXL335 should be I2C compliant; at least that's what I was told, when
I purchased it. The example that you posted is in the internal scripting
language for cloud9, correct? I am not familiar with that...I know only C
and C++, so I am not sure how can I use that to drive a C++ program on the
BBB.
Thanks for the info, I have something to start to study at least :)

Hi Karl,
I'm (quite) in the same approach as you do currently with a slightly
difference coming that I learn Xenomai for this too -Thanks Charles btw-
and use ADXL 335 and Invensense 9150.
For ADXL 335 -it's analog not I2C right ?- you could 1st test it with the
provided script : http://beagleboard.org/Support/BoneScript/accelerometer/
For invensense you are lucky as it's more supported than 9150 :
http://www.i2cdevlib.com/devices/mpu6050#source .
Anyway there are quite close so for C/C++ code you have things like this
that are great : https://github.com/Pansenti/linux-mpu9150
Hope this helps.

Hi all
I am learning how to use I2C, and I choose to use a gyro and an
accelerometer sensor, for my project.
The gyro is the MPU-6050, while the accelerometer is the ADXL335
I have the data sheet; but I don't see any code example that show how to
get the data and process it. Is there a library already available for the
BBB by any chance, for these 2 sensor?
I am not sure if others here use these sensor, but I was told that these
are the most common ones; but the only thing that pops up in a search is
related to the arduino.
Any pointer is more than welcome; Ideally I would like to write code in
C++, to drive an application that process the data; and having a library
that would interface with the device would save me time to write one
(unless necessary; why re-invent the wheel if this has been already done?)
Thanks in advance and sorry for the newbie question...If there was a book
showing how to do it, I would gladly buy it and study it.
