换句话说,ESP32 有自己的内部实时时钟,可以通过settimeofday( )进行设置,也可以通过 NTP 服务器进行设置。 参考:- ESP-IDF Programming Guide latest documentation 完整的工程代码: #include "I2C_BM8563.h" #include <WiFi.h> // RTC BM8563 I2C port // I2C pin definition for M5Stick & M5Stick Plus ...
In the ESP32 Series Datasheet (V4.6) it is clear to me that ESP32-D0WD-V3 has two I2C interfaces and can be routed to any GPIO pin. What happens is that they don't even mention I2C in the pin definition of the ESP32-WROOM-32E Datasheet and this has got me a bit confused. ...

首先,调用库函数,初始化I2C总线(类似于stm32那样) 这个初始化结构体看起来也挺简单 初始化模式 :Master IO口引脚 :ESP32具有两个I2C,分别映射到的引脚为18 19 25 26。我们这里选择I2C0,也就是I2C_NUM_0,对应18 19号引脚。 总线上拉使能 :enable ...
The ESP32 chips have a GPIO matrix that allows you to route most peripherals (like I2C) to any available GPIO pin. In other words: pick two convenient GPIO pins, make sure they're not otherwise occupied (flash connected to them, bootstrap pins etc), and you can use them as your I2C...
