I am using the XDK accelerometer in 16g mode. Now, even if there is no vibration, it gives a z axis value around 527. That means equals to 1g. I would like to know if its because of the gravitational acceleration, because, most of the accelerometers do not give this value as far as I know. Can anyone help?

Hi Ankit,

It is actually the earth acceleration. If you put the XDK on the side you see the 1g on another axis. But you could calibrate the sensor so that it outputs 0 in normal condition. Here are the functions you need: SDK / xdk110 / Platform / SensorToolbox

Can you give me some more details about calibrating the XDK to get a 0 mean in normal condition?

Hi Ankit,

I have no experience with calibration myself, so I just asked a colleague. A calibration is not required. If your application does not change the orientation of the XDK and you only want to measure the vibration, you can simply subtract the 527 in your implementation, or you can implement a high-pass filter that only filters out the permanent states.
