Zephyr Example Application

This repository contains a Zephyr example application. The main purpose of this repository is to serve as a reference on how to structure Zephyr based applications. Some of the features demonstrated in this example are:

• Basic application skeleton
• Custom boards
• Custom devicetree bindings
• Out-of-tree drivers
• Documentation using Doxygen and Sphinx
• Example CI configuration (using Github Actions)

Getting Started

Before getting started, make sure you have a proper Zephyr development environment. You can follow the official Zephyr Getting Started Guide.

Initialization

The first step is to initialize the workspace folder (my-workspace) where the example-application and all Zephyr modules will be cloned. You can do that by running:

# initialize my-workspace for the example-application (main branch)
west init -m https://github.com/zephyrproject-rtos/example-application --mr main my-workspace
# update Zephyr modules
cd my-workspace
west update

Build & Run

The application can be built by running:

west build -b $BOARD -s app

where $BOARD is the target board. The custom_plank board found in this repository can be used. Note that Zephyr sample boards may be used if an appropriate overlay is provided (see app/boards).

A sample debug configuration is also provided. You can apply it by running:

west build -b $BOARD -s app -- -DOVERLAY_CONFIG=debug.conf

Note that you may also use it together with rtt.conf if using Segger RTT. Once you have built the application you can flash it by running:

west flash
