.. zephyr:code-sample:: uart-passthrough
   :name: UART Passthrough
   :relevant-api: uart_interface

   Pass data directly between the console and another UART interface.

Overview
********

This sample will virtually connect two UART interfaces together, as if Zephyr
and the processor were not present. Data read from the console is transmitted
to the "*other*" interface, and data read from the "*other*" interface is
relayed to the console.

The source code for this sample application can be found at:
:zephyr_file:`samples/drivers/uart/passthrough`.

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

#. One UART interface, identified as Zephyr's console.
#. A second UART connected to something interesting (e.g: GPS), identified as
   the chosen ``uart,passthrough`` device - the pins and baudrate will need to
   be configured correctly.

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

Build and flash the sample as follows, changing ``nucleo_l476rg`` for your
board:

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/uart/passthrough
   :board: nucleo_l476rg
   :goals: build flash
   :compact:

개요

이 sample은 Zephyr와 processor가 없는 것처럼 UART interface 두 개를 가상으로 직접 연결합니다. Console에서 읽은 data는 다른 interface로 전송하고, 다른 interface에서 읽은 data는 console로 relay합니다.

Sample application source code는 samples/drivers/uart/passthrough에 있습니다.

요구 사항

  1. Zephyr console로 식별되는 UART interface 하나
  2. GPS 같은 대상에 연결된 두 번째 UART. 선택된 uart,passthrough device로 식별하며 pin과 baudrate를 올바르게 설정해야 합니다.

Build와 실행

다음과 같이 sample을 build하고 flash합니다. nucleo_l476rg는 사용하는 board 이름으로 바꾸십시오.

west build -b nucleo_l476rg samples/drivers/uart/passthrough
west flash
