Vlad Cazan / Mbed 2 deprecated XYZData

I plan on using my mbed to capture some raw acceleration data from a rocket that I plan to launch soon. What I have build is a little program that records data from an accelerometer. When you flip the switch, the program automatically starts recording all x,y, and z values to a cvs file which can later be opened in excel to produce a graph. I have also added a mobile lcd screen to output the results.

Dependencies:   mbed
