I'm not sure that I'm write in the right place. So if this topic does not match with the section, please move it.

I'm trying to work with a accelerometer from ST, the LSM303DLHC.
Now I can communicate with it and receive some data.

The problem is it the data are very unstable for axes X and Y, especially with it stopped, without any kind of shake.

Is it normal, with this conditions, the values changes between -200 and +200 (with scale of +-2g)?



Grateful for your help

 

Anyone can tell me if this is a normal situation?

 

I've never used that device, but a quick google showed that it uses I2C data interface;

I think the most likely cause of the problem is that your software is not working correctly to interface to the device.

Accelerometers when left alone always produce a highly stable output, never a change from -200 to +200!
