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.

Digixx 0:1e4aa22fc1a1 2 * @author Peter Swanson
Digixx 0:1e4aa22fc1a1 3 * A personal note from me: Jesus Christ has changed my life so much it blows my mind. I say this because
Digixx 0:1e4aa22fc1a1 4 * today, religion is thought of as something that you do or believe and has about as
Digixx 0:1e4aa22fc1a1 5 * little impact on a person as their political stance. But for me, God gives me daily
Digixx 0:1e4aa22fc1a1 6 * strength and has filled my life with the satisfaction that I could never find in any
Digixx 0:1e4aa22fc1a1 7 * of the other things that I once looked for it in.
Digixx 0:1e4aa22fc1a1 8 * If your interested, heres verse that changed my life:
Digixx 0:1e4aa22fc1a1 9 * Rom 8:1-3: "Therefore, there is now no condemnation for those who are in Christ Jesus,
Digixx 0:1e4aa22fc1a1 10 * because through Christ Jesus, the law of the Spirit who gives life has set
Digixx 0:1e4aa22fc1a1 11 * me free from the law of sin (which brings...) and death. For what the law
Digixx 0:1e4aa22fc1a1 12 * was powerless to do in that it was weakened by the flesh, God did by sending
Digixx 0:1e4aa22fc1a1 13 * His own Son in the likeness of sinful flesh to be a sin offering. And so He
Digixx 0:1e4aa22fc1a1 14 * condemned sin in the flesh in order that the righteous requirements of the
Digixx 0:1e4aa22fc1a1 15 * (God's) law might be fully met in us, who live not according to the flesh
Digixx 0:1e4aa22fc1a1 16 * but according to the Spirit."
Digixx 0:1e4aa22fc1a1 17 *
Digixx 0:1e4aa22fc1a1 18 * A special thanks to Ewout van Bekkum for all his patient help in developing this library!
