1. Introduction UART, full name Universal Asynchronous Receiver/Transmitter, translated as Universal Asynchronous Transceiver. The emergence of serial ports was around 1980, with data transmission rates of 115kbps～ 230kbps. Initially, serial ports were used to connect computer peripherals, typically connecting mice, external Modems, and old cameras and graphics tablets. Serial ports can also be used for … Read more
Reprinted from CSDN: https://blog.csdn.net/an520_/article/details/125479812 UART, SPI, I2C, and other serial communications are very common communication methods in embedded development. The underlying communication principles of these protocols are not difficult, but many beginners struggle to learn them. Today, I will share some common underlying data transmission principles. 1. UART Serial Port UART: Universal Asynchronous Receiver/Transmitter. The … Read more

In the previous article “UART Communication Interface Protocol – UART (I) Protocol Basics”, we briefly and meticulously describedUART configuration items and the signal timing of the communication process. This article will continue to introduce some interface specifications used by theUART interface under different electrical characteristics. 1. Introduction In fact,UART only defines the signal timing without … Read more
The serial port enables reliable communication between two terminal devices, functioning as the transport layer in this process. This article focuses on the data protocol. Similar Scenarios Hey! Hey! This is Dong Guai! Please respond! Please respond! over! Such dialogues are often seen in war-themed films when calling teammates through walkie-talkies or related wireless devices. … Read more
Embedded devices need to set parameters during operation, which is often accomplished by a PC. A communication protocol must be designed for both parties, with three representative protocols as follows: As can be seen from the table above, embedded devices generally have limited memory and computational performance, so fixed binary is the preferred communication protocol. … Read more
