The I2C Manual provides a broad overview of the various serial buses, why the I2C bus should be considered, technical detail of the I2C bus and how it works, previous limitations / solutions, ...

当前有很多串行通信协议，但其中I2C和SPI非常有名。这两种都是总线协议，允许用户进行短距离的串行数据传输。其中，I2C是飞利浦（现在是NXP）制造的两线通信，而SPI是摩托罗拉制造的。 这两种协议通常用于智能手机、电视和笔记本电脑等电子设备中，以控制 ...

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 ...

Delivers the flexible, multiple-peripherals simplicity of I2C and the faster, lower-latency communication of SPI in a single, efficient, easier-to-use IP core Woodcliff Lake, New Jersey — September 5, ...

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 ...

The first parallel-to-serial I2C interface lets designers add I2C interfaces to any digital system. The PCA9564 controller provides a 400-kHz I2C serial bus and operates from 2.5 to 3.3 V. The chip is ...

Jesus Echavarria has created a new design for a Dual USB Serial and I2C Converter he has created and released the schematic of the board making it available to download. The design is based on the on ...

The 24VL025 is a 2K I2C serial EEPROM. The device operates in a VCC ranging from 1.5 V to 3.6 V. It is organized as a single block of 256 x 8-bit memory with a 2-wire serial interface. Low-current ...

The CC-I2C_MST-APB is a synthesisable Verilog model of a I2C serial interface controller. The I2C core can be efficiently implemented on FPGA and ASIC ...
