IO_MUX和GPIO交换矩阵是ESP32芯片的两个重要模块，它们用于将外设信号传输到GPIO pad上，实现灵活的IO配置。 IO_MUX是指输入/输出 ...

Using hardware I2C on an ESP32? Do you need to connect multiple I2C devices with the same address? Normally, you wouldn’t be able to do that without extra parts, but on the ESP32, [BastelBaus ...

All of the ESP32 GPIO pins are terminated on a GPIO header, with jumper options to disable terminations to the standard interfaces and instead route them to the GPIO header as needed. Additionally ...

In fact, the underlying procedure is mostly the same even when you’re on an ESP32 board. Once you’ve connected the BME280 (or ...
