Why I²C is One of the Most Common Communication Protocols in Embedded Systems?

Why I²C is One of the Most Common Communication Protocols in Embedded Systems?

Why I²C is one of the most commonly used communication protocols in embedded systems?1. Background and Importance of I²C Communication The I²C (Inter-Integrated Circuit) communication protocol was developed in the 1980s by Philips (now NXP Semiconductors) to simplify communication between various integrated circuits within electronic devices. It is particularly suitable for scenarios requiring low-speed interconnection … Read more

Master-Slave Architecture in Multi-Agent Systems

In the past year, Multi-Agent systems have been gaining significant traction, with continuous funding and increasing popularity. From AutoGPT to MetaGPT, from CrewAI to LangGraph, various multi-agent frameworks are emerging. The domestic phenomenon Manus, along with the recently open-sourced OpenManus by the MetaGPT team, are notable examples. OpenAI’s Swarm, Microsoft’s AutoGen, and Anthropic’s Claude Code … Read more

In-Depth Analysis of the I2C Communication Bus: Physical Structure, Communication Structure, Timing, Protocol, and Operational Process

In-Depth Analysis of the I2C Communication Bus: Physical Structure, Communication Structure, Timing, Protocol, and Operational Process

I2C is a synchronous, half-duplex serial communication bus protocol used for connecting low-speed peripherals. The main features include: Two-wire system: SCL clock line and SDA data line Multi-master and multi-slave: Supports multiple master and slave devices, but only one master is allowed at any given time. Addressing: Each slave device has a unique address Speed: … Read more

Detailed Explanation of the SPI Protocol

Detailed Explanation of the SPI Protocol

Introduction to the SPI Protocol SPI is the Serial Peripheral Interface. It is a synchronous serial interface technology introduced by Motorola, characterized by high speed and full-duplex synchronous communication, capable of operating at frequencies exceeding hundreds of MHz. Typically, SPI requires four lines (for duplex communication), but it can also operate with three lines (for … Read more
