应用设计中，用一条I2C总线驱动多个I2C设备师很常见，实施也很简单，本项目将连接以下I2C设备： Adafruit_GFX, Adafruit_SSD1306.h 和 SPI.h，控制SSD1306 128×32 OLED显示屏。 由于所有元件相距不远，没必要I2C总线使用上拉电阻，因为这些杜邦线就是组件的一部分。 本项目 ...

很多人不知道怎么看着时序图写程序，下面结合一个非标准的I2C器件，教大家如何写一个高效的IO模拟I2C时序。 观察该时序，具备I2C的开始信号，I2C的结束信号，I2C的应答、非应答、响应应答，以及写字节和读字节的基本操作时序。 下面，我们一步一步分析。

A while ago I received a couple of I/O port expander modules that use the I 2 C protocol. Using that Chinese module, you can use only the SDA and SCL pins of your ...

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] has ...
