Re: ADXL345 accelerometer problems

And all of the wires are straight through? (VCC to VCC, SCL to SCL, SDA to SDA, GND to GND)

And can you get a voltage on SDA and SCL? They should be around 5 volts.

If possible, an oscilloscope would be useful in determining whether or not the I2C bus is working. You should hook up a probe to the SDA line, and confirm that the bits are changing.
