MMA8452Q - Strange reading values

Question asked by Sebastian Peryt on Nov 8, 2014

Hi,

 

I am currently testing MMA8452Q accelerometer in my application and during test I found totally strange values coming out. While normally all axis should be between 0 - 1 g from very beginning of measurements I have x axis value around 15g. This value is constant no matter if sensor is laying or I am moving it in any direction - all the time it is around 15g. Can someone give me advice what might be wrong? Is it something wrong with IC, or should I look somewhere else? For reference I am enclosing my readings.

 

Thank you in advance.
