9DOF Accelerometer Research and Dev

I spent some time last night working with the MPU-9150 breakout and a 16×2 LCD.  I pulled down some sample code from sparkfun’s github and played around with a few libraries.  I had challenges pushing data provided by the 9150 library to the LCD.  So, I did a little digging and found the MPU-6050 was more cooperative for me.
