   Interact with SMBus peripherals using shell commands.

Overview
********

This is a simple SMBus shell sample that allows arbitrary boards with SMBus
driver supported exploring the SMBus communication with peripheral devices.

Building and Running
********************

This sample can be found under :zephyr_file:`samples/drivers/smbus` in the
Zephyr tree.
The sample can be built and run as follows for the ``qemu_x86_64`` board:

.. zephyr-app-commands::
   :zephyr-app: zephyr/samples/drivers/smbus
   :host-os: unix
   :board: qemu_x86_64
   :goals: run
   :compact:

Sample Output
*************

Output from console when application started:

.. code-block:: console

   *** Booting Zephyr OS build zephyr-v3.2.0-804-gfedd72615e82  ***
   Start SMBUS shell sample qemu_x86_64

개요

SMBus driver를 지원하는 임의의 board에서 peripheral device와의 SMBus 통신을 살펴볼 수 있게 하는 간단한 SMBus shell sample입니다.

Build와 실행

이 sample은 Zephyr tree의 samples/drivers/smbus에 있습니다. qemu_x86_64 board용으로 다음과 같이 build하고 실행할 수 있습니다.

west build -b qemu_x86_64 zephyr/samples/drivers/smbus
west build -t run

Sample 출력

Application을 시작하면 console에 다음 내용이 출력됩니다.

*** Booting Zephyr OS build zephyr-v3.2.0-804-gfedd72615e82  ***
Start SMBUS shell sample qemu_x86_64
uart:~$
