ADXL345 I2C Accelerometer NOT WORKING

I have also tried using I2C directly and still got nothing.

I would like to try SPI, but I don't know how I would get the data back in the code, the DigitalInput class only returns boolean values, not doubles.

If someone could tell me how to use SPI in Java or what I'm doing wrong with the I2C I would really appreciate it!!! Thanks.

There is not currently an easy-to-use API in java for accessing SPI so I recommend against that (unless you are savvy C++ to Java porters and would like to contribute an implementation). I2C should work (works on the sensor I have) but check for errors on the console.
