Arduino代码–使用CardInfo测试SD卡模块 与SD卡进行通信需要大量工作,但对我们来说幸运的是,Arduino IDE已经包含一个非常不错的库SD,可简化对SD卡的读写操作。您可以在“示例”子菜单中看到它。 接下来,选择CardInfo示例草图。 该草图不会向卡中写入任何数据。它只是告诉您它是否能够识别卡,并显示有关它的一些信...

If your application uses the micro SD card reader, only pins 2 3 and 16 are available. However, the following constraints must be taken into account: The GPIO16 pin not being RTC, it will not be possible to wake up the ESP32-CAM using a PIR motion detector for example. ...
