Components for ESP-IDF Development

There are some C++ components for ESP-IDF Development.

An overview can be found at Physical Computing.

Integrated Development Environment

I’m using a simple IDE for the ESP-IDF Development on my MacBook.

First I did the standard toolchain installation as described by Espressif here. This will install the ESP-IDF environment on your computer.

Then I installed the community edition of IntelliJ IDEA.

Building and Deploying a Component

To build and deploy a component to an ESP32 SoC follow these steps in IntelliJ IDEA:

We will walk through the steps with component wifi_manager on an ESP32C3 system.

• Clone the repository of the component on GitHub to your computer:
  Open IntelliJ IDEA, click on “Clone Repository” and enter the GiHub URL of wifi_manager: https://github.com/elrebo-de/wifi_manager.git
• In the project wifi_manager, which you have cloned, open a terminal.
• In the terminal call the export command of ESP-IDF to make the idf commands available:
  source /Users/christophoberle/esp-idf/esp-idf/export.sh
  The directory on your computer will be different. It is the location of the esp-idf environment to be used.
• Navigate to the example directory: cd example/wifi_manager_test
• Set the target with: idf.py set-target esp32c3
  Now the build files for an ESP32C3 board are created.
• Build the program with: idf.py build
  Now the ESP32C3 images are created.
• Connect the ESP32C3 board to your computer with a USB cable.
• Flash the program to the ESP32C3 system and run it with:
  idf.py flash monitor
  Now the program is written onto the device and it is started. The log will be written to the terminal.
