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(Inter-Integrated Circuit)总线(也称 IIC 或 I2C) 是有PHILIPS公司开发的两线式串行总线，用于连接微控制器及外围设备，是微电子通信控制领域广泛采用的一种总线标准。它是同步通信的一种特殊形式，具有接口线少、控制方式简单、器件封装形式小、通信速率较高等 ...

You only really need two data wires to transfer a ton of data. Standards like UART, USB2, I2C, SPI, PS/2, CAN, RS232, SWD (an interface to program MCUs), RS485, DMX, and many others, all are a ...

I2C协议是在开发中使用非常频繁的一种协议，相信大家在学习单片机的时候经常会用到支持I2C协议的模块，I2C 总线仅仅使用 SCL、SDA 这两根信号线就实现了设备之间的数据交互，极大地简化了对硬件资源和 PCB 板布线空间的占用。因此，I2C 总线被非常广泛地应用 ...

The availability of powerful I2C buffers that drive their I/Os on both sides to a nominal ground or ‘zero offset’ logic level allows the removal of noise introduced into one section of a larger bus ...

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

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...

The I2C-MS core is a controller for the Inter-Integrated Circuit (I2C) bus. The highly configurable core can implement an I2C bus master, slave, or a ...

The circuit shown can be used to interface multiple serial devices to the I2C bus, even if they lack the extended-addressing capability required. Information transfer be-tween I2C devices connected to ...
