I2C是一种广泛应用于嵌入式系统中的短距离串行通信协议，支持多主多从设备模式，主机通过时钟信号SCL和数据线SDA与从机进行数据交互。在 RT-Thread 操作系统中，我们可以通过菜单配置工具menuconfig快速设置软件 I2C 的引脚，并借助其内部已实现的驱动程序 ...

做硬件设计，但是以前很少做micom关联的，软件更是没做过， 最近要设计几个MCU之间的通讯， 发现好多名词理解的不是很清楚，还会混淆，求大神帮忙解释下他们的作用及关系。 SDA,SCL,RX,TX 还有CLK啊。 谢谢。

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 ...

In this article, we will clarify how to build a bidirectional 2-bit mux circuit that can be used with I 2 C lines. The circuit also has the extra functionality of operating as a level shifter, if ...

This 8-bit I/O expander for the two-line bidirectional bus (I2C) is designed to provide general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL) ...
