Calibration of the accelerometer
Posted: 23:37, 02 Jul 2015
Hello. I'm starting my "leveler" app and everything works fine.
I'm obtaining from the accelerometer some raw data from X, Y and Z axes, but they are not "0" of course: they change in a fixed interval. I want to set a reference (calibration), maybe using the red button on the SensorTag, and then I want to convert the raw data in roll and pitch degree.
Someone has something ready (maybe a library with some helpers)?
Is possibile to save the three calibration value on the tag? Is there a small memory storage available to use?
