adxl345z i2c

[Roberto]

Hi i have to use this accelerometer and connect it through i2c

www.analog.com/.../EVAL-ADXL345Z.pdf

This is my connection:

VIO --> 3.3V GND --> GND CS --> 3.3V Vs --> ? SCL --> Pin x SDA --> Pin y SDO --> GND

But i cannot read data. I only see 0 0 0. Is it burned or i have done something wrong in the connection?

The Vs (voltage supply) it must be connected or not? and where? to 3.3V?

Thanks in advance

Hi,

Please take a look at this Quick Start Guide. Figure 4 in the guide shows you how to connect the adxl345z for i2c mode. Vs must be supplied(3.3 V is OK). See this data sheet for more information, take a look at the POWER SEQUENCING chapter (page 13).
