James Watanabe / ADXL345

Forked from Uwe Gartmann's ADXL345 library, customized as part of the 9DOF stick from Sparkfun.com

Fork of ADXL345 by Uwe Gartmann

ADXL345 is triple axis, digital interface, accelerometer.

This library is forked from Uwe Gartmann and Peter Swanson's work.

This library is for specific application using 9DoF-Stick.

Datasheet:

http://www.analog.com/static/imported-files/data_sheets/ADXL345.pdf

ADXL345は3軸のデジタルインターフェースを備えた加速度センサです。

このライブラリは 9DoF-Stick を使用した特定の企画のために保守しています。

mbed IDEが日本語をサポートするまでは英語でコメントを書いていきますが、サポートした後もきっと英語で書いていくでしょう。
