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 ...

When an air quality display project needed a display, [Inderpreet] looked into small character-based LCDs. [Inderpreet’s] chosen LCD used an I2C interface, which was new to him. Rather than shy away, ...

I2C不是AUTOSAR中标准的MCAL模块，所以I2C在车载电控件中基本不用（一般都使用SPI），但是因为I2C一主多从只需要两个Pin脚就能控制多个外设的特性，在一些带SOC的控制器中会使用到，且Vector的SIP包中也有I2C模块，所有有必要学下以下，本文就概要的介绍下TC3xx芯片 ...

i2c的设备树和驱动是如何匹配以及何时调用probe的？粉丝手里的I2C外设是ov5640，一个摄像头。粉丝提问，一口君必须安排。 i2c_device_match（），匹配总线维护的驱动链表和设备信息链表，如果其中名字完全相同，则返回true，否则false；i2c_device_probe（），当 ...

This FAQ analyzes the open-drain physical layer and the nuances of register-level addressing to better understand I2C communication.

If you’ve ever been laying out a network I2C devices inside a project box or throughout your robot’s body, you’ll probably know that I2C is not without its pitfalls. But for many of those pitfalls, ...

This dual bidirectional I2C buffer is operational at 2.7 V to 5.5 V. The TCA9517 is a BiCMOS integrated circuit intended for I2C bus and SMBus systems. It can provide ...

NXP Semiconductors’ family of level shifting bus buffers are detailed in this application note that discusses device operation, maximum cable length and frequency ...

NXP Semiconductors has introduced its first no-offset I2C-bus buffers, which are designed to isolate capacitance and so allow interface with other bus buffers. Significantly, the bus buffers use the ...
