在本教程中,我们将学习使用 ESP32 I2C 通信 通道。我们将学习如何使用 ESP32 除了默认 I2C 引脚之外的不同引脚进行 I2C 通信,将不同的 I2C 设备连接到同一总线,以及如何使用两个 I2C 总线接口。此外,我们将 ESP32 与通过 I2C 协议通信的不同传感器和设备连接,并对我们的板进行编程以运行 I2C 扫描仪。该扫描...

ESP32-CAM具有非常明亮的内置LED,可以在拍摄照片时用作闪光灯。该LED内部连接到GPIO 4。该GPIO也已连接到microSD卡插槽,因此尝试同时使用它们时可能会遇到麻烦-使用microSD卡时手电筒将点亮。注意:我们的一位读者分享说,如果按照以下方式初始化microSD卡,则不会出现此问题,因为microSD卡不会使用该数据线。*...

we have a total of 36 GPIO pins, but we will be usingGPIO22as a digital output pin. On different boards, these pins can be located at different locations. Therefore, you need to check its datasheet before using pin number in programming which I will explain in the programming part of ...
