The manual for the HSCDTD008A gives us a scaling for the three axis as +/- 2.4mT (24 Gauss) per axis. The manual for the AMI305 and AMI306 gives us a scaling for the three axis as +/- 12 Gauss per axis. Tests with the HSCDTD008A sensor, cat the raw values: $ cat in_magn_*_raw raw 45 189 -19 The scaling factor in in_magn_*_scale is 0.001464843, which gives: 0.065 Gauss 0.277 Gauss -0.027 Gauss The earths magnetic field is in the range of 0.25 to 0.65 Gauss on the surface according to Wikipedia, so these seem like reasonable values. Again we are guessing that the AK8974 has a 12 bit ADC, based on the similarity with AMI305 and AMI306.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
