As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>. This patch proposes to then include <zephyr/kernel.h> instead of <zephyr/zephyr.h> since it is more clear that you are including the Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a catch-all header that may be confusing. Most applications need to include a bunch of other things to compile, e.g. driver headers or subsystem headers like BT, logging, etc. The idea of a catch-all header in Zephyr is probably not feasible anyway. Reason is that Zephyr is not a library, like it could be for example `libpython`. Zephyr provides many utilities nowadays: a kernel, drivers, subsystems, etc and things will likely grow. A catch-all header would be massive, difficult to keep up-to-date. It is also likely that an application will only build a small subset. Note that subsystem-level headers may use a catch-all approach to make things easier, though. NOTE: This patch is **NOT** removing the header, just removing its usage in-tree. I'd advocate for its deprecation (add a #warning on it), but I understand many people will have concerns. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no> |

.. _accel_polling:
Generic 3-Axis accelerometer polling sample
###########################################
Overview
********
This sample application demonstrates how to use 3-Axis accelerometers.
Building and Running
********************
This sample supports up to 10 3-Axis accelerometers. Each accelerometer needs
to be aliased as ``accelN`` where ``N`` goes from ``0`` to ``9``. For example:
.. code-block:: devicetree
/ {
aliases {
accel0 = &lis2dh;
};
};
Make sure the aliases are in devicetree, then build and run with:
.. zephyr-app-commands::
:zephyr-app: samples/sensor/accel_polling
:board: <board to use>
:goals: build flash
:compact:
