.. zephyr:code-sample:: w1-scanner
   :name: 1-Wire scanner
   :relevant-api: w1_interface

   Scan for 1-Wire devices and print their family ID and serial number.

Overview
********

This sample demonstrates how to scan for 1-Wire devices. It runs the 1-Wire
scan routine once and prints the family id as well as serial number of the
devices found.

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

Set DTC_OVERLAY_FILE to "ds2484.overlay" or "w1_serial.overlay" in order to
enable and configure the drivers.
