What a blessed day today, I got my 6DOF Digital IMU earlier this morning (3 days ahead of time) and just a couple of hours' effort and it's up and running.
I have used Fabio's blog (the one mentioned above by Lauszus) http://www.varesano.net/blog/fabio/my-first-6-dof-imu-sensors-fusion-implementation-adxl345-itg3200-arduino-and-processing
All the Arduino & Processing code is available on the link above. It took me a couple of hours to establish the whole link as it was my first ever interaction with "Processing", Otherwise it was just a matter of a few minutes. Fabio's code is quite nicely written and commented wherever necessary. The only change I had to make in the code was to change Gyro Address (from 0x69 to 0x68), that too mentioned by Fabio.
The interfacing of the sensor with Arduino is too simple (3.3V, GND, SDA and SCL) of sensor to (3.3V, GND, A4 and A5 respectively) of Arduino.
Since all is hooked up now and running like a charm, it's time to give another "good reading" to Lauszus's article ;-)
Lauszus, I am just loving the way you write.
I don't know about you guys but since I am new to Arduino/electroics, my way of accomplishing a task is usually as follows.
1. Interfacing - Get the electronics (sensors, wires, resistors, capacitors etc) and hook them all up
2. Interaction - Get the code, algorithm (wherever applicable) and read the data
3. Understanding - Since by now I have had a working model of what I wanted to experiment on. At this point I start playing with the "toy" and do a lot of R&D to understand the concept and know and insight of the blackbox. And that's done by Google readings and Forum postings.
OK guys, billions of thanx to all of you. it's like a big milestone hit for me. Thanx to Google but people like you are cherry on the cake (make it '"cherries" instead ;-)
