Sensor Shell Module Sample
##########################
Overview
********
This is a simple shell module to get data from sensors presented in the system.
Building and Running
********************
Build the sample app by choosing the target board that has sensors drivers
enabled, for example:
.. zephyr-app-commands::
:zephyr-app: samples/subsys/shell/sensor_module
:board: reel_board
:goals: build flash
Shell Module Command Help
=========================
.. code-block:: console
sensor - Sensor commands
Subcommands:
get :Get sensor data. Channel names are optional. All channels are read when
no channels are provided. Syntax:
<device_name> <channel name 0> .. <channel name N>
**get**: prints all the sensor channels data for a given sensor device name.
Optionally, a single channel name or index can be passed to be printed out. The
device name and channel name are autocompleted.
Output example (reel_board):
.. code-block:: console
uart:~$ sensor get mma8652fc@1d
channel idx=0 accel_x = 0.000000
channel idx=1 accel_y = 0.268150
channel idx=2 accel_z = 9.959878
channel idx=3 accel_xyz x = 0.000000 y = 0.268150 z = 9.959878
uart:~$ sensor get mma8652fc@1d accel_z
channel idx=2 accel_z = 9.959878
uart:~$ sensor get mma8652fc@1d 2
channel idx=2 accel_z = 9.959878
.. note::
A valid sensor device name should be passed otherwise you will get an
undefined behavior like hardware exception. This happens because the shell
subsystem runs in supervisor mode where API callbacks are not checked before
being called.
