3️⃣ Quick Start 🎁

🟢 PlatformIO is recommended because these examples were developed on it. 🟢

1、PlatformIO

1. Install Visual Studio Code and Python, and clone or download the project;
2. Search for the PlatformIO plugin in the VisualStudioCode extension and install it;
3. After the installation is complete, you need to restart VisualStudioCode
4. After opening this project, PlatformIO will automatically download the required tripartite libraries and dependencies, the first time this process is relatively long, please wait patiently;
5. After all the dependencies are installed, you can open the platformio.ini configuration file, uncomment in example to select a routine, and then press ctrl+s to save the .ini configuration file;
6. Click ☑️ under VScode to compile the project, then plug in USB and select COM under VScode;
7. Finally, click the ➡️ button to download the program to Flash;

2、Arduino IDE

1. Install Arduino IDE

2. Copy all files under this project/lib/ and paste them into the Arduion library path (generally C:\Users\YourName\Documents\Arduino\libraries);

3. Open the Arduion IDE and click File->Open in the upper left corner to open an example in this project/example/xxx/xxx.ino under this item;

4. Then configure Arduion. After the configuration is completed in the following way, you can click the button in the upper left corner of Arduion to compile and download;
