Sylvio Alves 4a4d7584ff boards: rename and update esp32 related conf and overlay files There are several esp32-based boards that its conf and overlay files are missing proper renaming to match cpu cluster. This also removes all _SOC_ name from files. Signed-off-by: Sylvio Alves <sylvio.alves@espressif.com>		2024-04-23 15:36:13 +02:00

.. zephyr:code-sample:: alarm
   :name: Counter Alarm
   :relevant-api: counter_interface

   Implement an alarm application using the counter API.

Overview
********
This sample provides an example of alarm application using :ref:`counter API <counter_api>`.
It sets an alarm with an initial delay of 2 seconds. At each alarm
expiry, a new alarm is configured with a delay multiplied by 2.

.. note::
   In case of 1Hz frequency (RTC for example), precision is 1 second.
   Therefore, the sample output may differ in 1 second

Requirements
************

This sample requires the support of a timer IP compatible with alarm setting.
