Development Environment Configuration

• The following development system is Windows by default

ESP-IDF

• It is recommended to use the VSC plugin for development

Develop with VSCode Plug-in

Install VSCode

1. Open the download page of the official VSCode website, and select the corresponding system and system bit to download
   Esp32-vscod-01.jpg
2. After running the installation package, the rest can be installed by default, but here for the subsequent experience, it is recommended to check boxes 1, 2, and 3
   Esp32-vscod-02.jpg
   • After the first two items are enabled, you can open VSCode directly by right-clicking files or directories, which can improve the subsequent user experience
   • After the third item is enabled, you can select VSCode directly when you choose how to open it

Install Espressif IDF Plugin

• Note: Currently the latest version of the plugin is V1.6.0, users can choose the same version as us for a consistent experience

1. Open VSCode, use Shift+Ctrl+X enter the plug-in manager
   Esp32-vscod-03.jpg
2. In the search bar, enter Espressif IDF to select the corresponding plug-in and click Install
   Esp32-vscod-04.jpg
3. Use the shortcut key F1 and enter
