12Building and Running
13********************
14
15This sample supports up to 10 3-Axis accelerometers. Each accelerometer needs
16to be aliased as ``accelN`` where ``N`` goes from ``0`` to ``9``. For example:
17
18.. code-block:: devicetree
19
20 / {
21 aliases {
22 accel0 = &lis2dh;
23 };
24 };
25
26Make sure the aliases are in devicetree, then build and run with:
