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 ...

I2C 相关的硬件问题汇总及死锁解决办法 IIC 是一个两线串行通信总线，包含一个 SCL 信号和 SDA 信号，SCL 是时钟信号，从主设备发出，SDA 是数据信号，是一个双向的，设备发送数据和接收数据都是通过 SDA 信号。 在设计 IIC 信号电路的时候我们会在 SCL 和 SDA 上加 ...

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 ...

I2C is a two-wire, bidirectional bus protocol that enables effective communication between one master (or multiple masters) and one or more slave devices. It is a straightforward, half-Duplex, ...

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 ...
