3.1 Arduino IDE还是PlatformIO 零基础我推荐 Arduino IDE ，因为库安装简单，示例多。 但如果你已经熟悉VS Code，PlatformIO更舒服，依赖管理清晰。 两个我都用过，下面以Arduino IDE为主讲，PlatformIO的配置我会在代码部分顺带提。 Arduino IDE需要先装ESP32的开发板支持。
RFID无线射频识别技术通过13.56MHz电磁波实现非接触式卡号读取，其核心在于读卡器与卡片间的电磁感应与SPI通信协议。在物联网开发中，ESP32凭借丰富的GPIO、稳定的SPI接口和内置WiFi，成为驱动MFRC522模块的理想平台。掌握这一技术，不仅能构建门禁、考勤等实用系统，还能深入理解嵌入式硬件通信与 ...
