Overview

Quick Start

Example Support

PlatformIO

1. Install VisualStudioCode, choose the version for your system.

2. Open the "Extensions" in the sidebar of Visual Studio Code (or use Ctrl+Shift+X), search for the "PlatformIO IDE" extension and install it.

3. While the extension is installing, you can go to GitHub to download the program. You can download the main branch code by clicking the green "<> Code" button, or download the "Releases" version from the sidebar.

4. After the extension is installed, open the sidebar's Explorer (or use Ctrl+Shift+E), click "Open Folder", find the project code you just downloaded (the entire folder), click "Add", and the project files will be added to your workspace.

5. Open the "platformio.ini" file in the project folder (PlatformIO will automatically open the "platformio.ini" of the corresponding folder after adding it). Under the "[platformio]" section, uncomment to select the example program you want to upload (marked by "default_envs = xxx"). Then click the "[√]" at the bottom left to compile. If the compilation is successful, connect the microcontroller to your computer and click "[→]" at the bottom left to upload.

Arduino

1. Install Arduino IDE, choose the version for your system.

2. Open the "example" directory in the project folder, select the example project folder, and open the file ending with ".ino" to open the Arduino IDE project workspace.

3. Open the "Tools" menu in the top bar -> Select "Board" -> "Boards Manager", find or search for "esp32", and install the board files by "Espressif Systems". Then return to the "Board" menu and select the board type under "ESP32 Arduino". The board type to select is determined by the "board = xxx" header under the [env] section in the "platformio.ini" file. If the corresponding board is not available, you need to manually add the board from the "board" directory in the project folder.

4. Open the menu bar "File" -> "Preferences", find the "Sketchbook location" field, and copy all the library files along with their folders from the "libraries" folder in the project directory to the "libraries" folder in this location.

5. Select the correct settings in the "Tools" menu as shown in the table below.

6. Select the correct port.

7. Click the "√" in the top right corner to compile. If the compilation is successful, connect the microcontroller to your computer and click "→" in the top right corner to upload.

Development Platforms

1. Micropython
2. Arduino IDE
3. Platform IO
