This library enables users to communicate with the ADXL345 accelerometer through the I2C bus on the mbed. The API names are similar and work nearly the same way as those made in the SPI libraries for the ADXL345.

| peterswanson87 | 0:d0adb548714f | 2 | * @author Peter Swanson |
| peterswanson87 | 0:d0adb548714f | 3 | * A personal note from me: Jesus Christ has changed my life so much it blows my mind. I say this because |
| peterswanson87 | 0:d0adb548714f | 4 | * today, religion is thought of as something that you do or believe and has about as |
| peterswanson87 | 0:d0adb548714f | 5 | * little impact on a person as their political stance. But for me, God gives me daily |
| peterswanson87 | 0:d0adb548714f | 6 | * strength and has filled my life with the satisfaction that I could never find in any |
| peterswanson87 | 0:d0adb548714f | 7 | * of the other things that I once looked for it in. |
| peterswanson87 | 0:d0adb548714f | 8 | * If your interested, heres verse that changed my life: |
| peterswanson87 | 0:d0adb548714f | 9 | * Rom 8:1-3: "Therefore, there is now no condemnation for those who are in Christ Jesus, |
| peterswanson87 | 0:d0adb548714f | 10 | * because through Christ Jesus, the law of the Spirit who gives life has set |
| peterswanson87 | 0:d0adb548714f | 11 | * me free from the law of sin (which brings...) and death. For what the law |
| peterswanson87 | 0:d0adb548714f | 12 | * was powerless to do in that it was weakened by the flesh, God did by sending |
| peterswanson87 | 0:d0adb548714f | 13 | * His own Son in the likeness of sinful flesh to be a sin offering. And so He |
| peterswanson87 | 0:d0adb548714f | 14 | * condemned sin in the flesh in order that the righteous requirements of the |
| peterswanson87 | 0:d0adb548714f | 15 | * (God's) law might be fully met in us, who live not according to the flesh |
| peterswanson87 | 0:d0adb548714f | 16 | * but according to the Spirit." |
