Setting Up the Development Environment

To start working with the ESP32, you need to set up your development environment. Here are the required tools and software:

Required Tools and Software:

1. Visual Studio Code (VSCode)

2. ESP-IDF (Espressif IoT Development Framework)

3. Python and Git

Installing Visual Studio Code (VSCode):

1. Download VSCode: Go to the Visual Studio Code website and download the version suitable for your operating system.

1. Install VSCode: Follow the installation instructions on the website to install VSCode on your computer.

Installing ESP-IDF Extension:

1. Open VSCode: Once installed, open Visual Studio Code.

2. Install the Extension: Click on the Extensions icon in the left sidebar. In the search bar, type "ESP-IDF" and install the official ESP-IDF extension by Espressif.

click on Configure Extension

Choose Express first option.

Make sure your configuration look like below Image and press Install.

After Completion of Installation Click on ESP-IDF extension

Then click on Show Example Then hello_world

Now Click Create project using example

Select Destination folder.

If you able to get below image Window means you have successfully created a project.

Then click on main folder and open hello_world.c.

Now Select your com port and click on build project

You can see logs in the terminal window for every new project. The first build will take more time.

After successful build you will see below log in output tab.

Now click on Flash Device and select UART

You will see the message below in the terminal window. Then, press the boot button on the ESP32 for 3 seconds. After this, the flash will start automatically. If the flash starts before 3 seconds, then, you can release the boot button earlier.

After successful flash you can see below log on terminal window.

Now from ESP-IDF menu select Monitor tab.

On serial monitor you can see Hello world! print and every 10 seconds esp32 will restart and again you can see same print with restarting countdown logs.

Now you have successfully installed IDE and created Development environment for ESP-IDF.
