I'm trying to implement free-fall using ADXL345 but when I keep my ADXL flat on a surface, Z axis raw is around 4g. I tried bringing it down by updating the offset reg with maximum negative value (0x80) but I could only manage bringing it down to 2g. I want to bring it down to 1g, so , is there any way it can be done. I have tried ±2g, ±4g, ±8g, ±16g and full resolution but my results are same and as a result I'm unable to implement free-fall.
