ADXL3xx 3-axis accelerometer example for Educational BoosterPack MK II
http://boosterpackdepot.info/wiki/index.php?title=Educational_BoosterPack_MK_II
Absolute rating/conversion can be determined from the ADXL3xx datasheet.
As a quick reference, for LaunchPads with 12-bit ADC (MSP430F5529, Tiva C, etc.),
the entire analog range is [0,4096]. For simple tilting calculation
[-1g,1g] ~ = [mid-800, mid + 800] = [2048-800,2048+800] = [1248,2848]
Modified from ADXL3xx example by David A. Mellis & Tom Igoe
Reads an Analog Devices ADXL3xx accelerometer and communicates the
acceleration to the computer. The pins used are designed to be easily
compatible with the breakout boards from Sparkfun, available from:

The circuit:
* analog 25: z-axis
* analog 24: y-axis
* analog 23: x-axis
