.. zephyr:code-sample:: timeaware-gpio
   :name: Time-aware GPIO
   :relevant-api: tgpio_interface

   Synchronize clocks.

Overview
********

A sample application that can be used with any supported boards. eg. RPL.
prints configuration info to the console. Below functionalities are tested:

1. Periodic pulse generation (an Oscilloscope or loopback may be required)
2. Input pulse timestamping (a pulse generator or loopback may be required)

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

This application can be built and executed as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/misc/timeaware_gpio
   :board: intel_rpl_crb
   :host-os: unix
   :goals: build


To build for another supported board, change "intel_rpl_crb" to that board's
name (if supported).

개요

지원되는 모든 board, 예를 들어 RPL에서 사용할 수 있는 sample application입니다. 설정 정보를 console에 출력하며 다음 기능을 시험합니다.

  1. 주기적 pulse 생성. Oscilloscope 또는 loopback이 필요할 수 있습니다.
  2. 입력 pulse timestamp 기록. Pulse generator 또는 loopback이 필요할 수 있습니다.

Build와 실행

다음과 같이 application을 build하고 실행할 수 있습니다.

# From the root of the zephyr repository
west build -b intel_rpl_crb samples/drivers/misc/timeaware_gpio

지원되는 다른 board용으로 build하려면 intel_rpl_crb을 해당 board 이름으로 바꾸십시오.
