.. zephyr:code-sample:: mbox_data
   :name: MBOX Data
   :relevant-api: mbox_interface

   Perform inter-processor mailbox communication using the MBOX API with data.

Overview
********

This sample demonstrates how to use the :ref:`MBOX API <mbox_api>` in data transfer mode.
It can be used only with mbox driver which supports data transfer mode.

Sample will ping-pong up to 4 bytes of data between two cores via two mbox channels.
After each core receives data, it increments it by one and sends it back to other core.

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

The sample can be built and executed on boards supporting MBOX with data transfer mode.

Sample Output
=============

Open a serial terminal (minicom, putty, etc.) and connect the board with the
following settings:

- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1

Reset the board and the following message will appear on the corresponding
serial port, one is the main core another is the remote core:

개요

이 sample은 data transfer mode에서 MBOX API를 사용하는 방법을 보여줍니다. Data transfer mode를 지원하는 mbox driver에서만 사용할 수 있습니다.

Sample은 mbox channel 두 개를 통해 두 core 사이에서 최대 4byte data를 ping-pong합니다. 각 core는 data를 수신할 때마다 값을 1 증가시킨 뒤 다른 core로 돌려보냅니다.

Build와 실행

Data transfer mode의 MBOX를 지원하는 board에서 sample을 build하고 실행할 수 있습니다.

Sample 출력

Minicom이나 PuTTY 같은 serial terminal을 열고 다음 설정으로 board에 연결합니다.

Speed: 115200
Data: 8 bits
Parity: None
Stop bits: 1

Board를 reset하면 해당 serial port 두 곳에 다음 message가 나타납니다. 하나는 main core이고 다른 하나는 remote core입니다.
