# Examples
|
|
|
|
This directory contains a range of example ESP-IDF projects. These examples are intended to demonstrate parts of the ESP-IDF functionality, and to provide code that you can copy and adapt into your own projects.
|
|
|
|
# Example Layout
|
|
|
|
The examples are grouped into subdirectories by category. Each category directory contains one or more example projects:
|
|
|
|
* `bluetooth/bluedroid` Classic BT, BLE and coex examples using default Bluedroid host stack.
|
|
* `bluetooth/nimble` BLE examples using NimBLE host stack.
|
|
* `bluetooth/esp_ble_mesh` ESP BLE Mesh examples.
|
|
* `bluetooth/hci` HCI transport (VHCI and HCI UART) examples.
|
|
* `build_system` Examples of build system features.
|
|
* `cxx` C++ language utilization examples and experimental components.
|
|
* `ethernet` Ethernet network examples.
|
|
* `get-started` Simple examples with minimal functionality. Good start point for beginners.
|
|
* `mesh` Wi-Fi Mesh examples.
|
|
* `network` Examples related to general network environment, test & analysis.
|
|
* `openthread` OpenThread examples.
|
|
* `peripherals` Examples showing driver functionality for the various onboard ESP32 peripherals.
|
|
* `protocols` Examples showing network protocol interactions.
|
|
* `provisioning` Wi-Fi provisioning examples.
|
|
* `security` Examples about security features.
|
|
* `storage` Examples showing data storage methods using SPI flash, external storage like the SD/MMC interface and flash partitioning.
|
|
* `system` Demonstrates some internal chip features, or debugging & development tools.
|
|
* `wifi` Advanced Wi-Fi features (For network protocol examples, see `protocols` instead.)
|
|
|
|
In addition to these examples, `commmon_components` directory contains code shared by several examples.
|
|

# Using Examples
|
|
|
|
Before building an example, be sure to follow the [ESP-IDF Getting Started Guide](https://idf.espressif.com/) to ensure you have the required development environment.
|
|
|
|
Building an example is the same as building any other project:
|
|
|
|
* Change into the directory of the new example you'd like to build.
|
|
* Run `idf.py set-target TARGET` to select the correct chip target to build before opening the project configuration menu. By default the target is `esp32`. For all options see `idf.py set-target --help`
|
|
* Run `idf.py menuconfig` to open the project configuration menu. Most examples have a project-specific "Example Configuration" section here (for example, to set the WiFi SSID & password to use).
|
|
* `idf.py build` to build the example.
|
|
* Follow the printed instructions to flash, or run `idf.py -p PORT flash`.
|
|
|
|
# Copying Examples
|
|
|
|
Each example is a standalone project. The examples *do not have to be inside the esp-idf directory*. You can copy an example directory to anywhere on your computer in order to make a copy that you can modify and work with.
|
|
|
|
The `IDF_PATH` environment variable is the only thing that connects the example to the rest of ESP-IDF.
|
|
|
|

In the ESP-IDF documentation, you can find a "Creating Examples" page which lays out the steps to creating a top quality example.
