So far, protocols like I2C, SPI, and UART remain the most commonly used communication protocols in electronic embedded devices. In this article, we will analyze these three protocols to provide a clear and intuitive understanding of their functions, advantages, and limitations, supplemented with GIF animations. I2C Protocol I2C is a serial communication protocol commonly used … Read more
Follow+Star Public Number, don’t miss exciting content Author | strongerHuang WeChat Official Account | strongerHuang Recently, I saw some netizens discussing whether ‘CAN is more difficult than UART’ in a technical group. Some said CAN is easy, while others said it is difficult. In fact, whether it is difficult or not mainly depends on your … Read more
I2C Communication Protocol Basics 3.1 Introduction to Communication I²C (Inter-Integrated Circuit) is a serial communication bus designed by Philips in the early 1980s. It facilitates communication between motherboards, embedded systems, or mobile phones and peripheral devices. Due to its simplicity, it is widely used for communication between microcontrollers and sensor arrays, displays, IoT devices, EEPROMs, … Read more
1. Qiu Qianzhang’s Lightness Skill: UART In the Legend of the Condor Heroes, Qiu Qianzhang says that UART is like my lightness skill, allowing me to float over water to cross rivers. To communicate (cross the river), set up hidden stakes in advance, and during the crossing, maintain a fixed step based on the distance … Read more
1.I2C: Inter-Integrated Circuit, abbreviated as I2C Bus. I2C mainly distinguishes slave devices through addresses, and its communication principle is relatively simple. 2.SPI: Serial Peripheral Interface, a common serial synchronous communication protocol widely used in applications. 3.UART: Universal Asynchronous Receiver/Transmitter, a serial, asynchronous, full-duplex communication protocol.

UART, I2C, RS485… These communication protocols are commonly used, but their explanations can be ambiguous. I feel it’s necessary to organize them to consolidate and differentiate. The article is a bit long, so I suggest saving it for later reference. UART stands for Universal Asynchronous Receiver-Transmitter. The UART port refers to a type of physical … Read more
