When I got the 3 acceleration, the resultant acceleration is not 9.81, it is like 9.31
There are some post said I need to leave the chip for 5-10 mins for calibration.
I think the calibration is just for the offset, right? So, even without the calibration, should the resultant force be 1g? Does the temperature only affect the offset? Will the temperature affect the scaling of 16384/g?
Plan B, as the chip is as rest, I use the 3 values as the offset, then, the resultant acceleration value will be the true acceleration.
