1 UART UART is an asynchronous serial communication protocol, with the full English name Universal Asynchronous Receiver/Transmitter. Unlike communication protocols such as SPI and I2C, it is also a commonly used IP in SoCs. Its greatest advantage is that it uses only two wires for communication, supporting full-duplex, meaning one wire (UTx) is used for … Read more

Learn more in this article. Any form of communication requires rules to help ensure everyone stays consistent. In the electronics field, these rules … Read more
In serial communication, both parties are required to use a standard interface, allowing different devices to connect easily for communication. The RS-232 communication standard is defined by a 25-pin interface and was widely used in early computers such as PC or XT models. However, in models after the AT series, a simplified 9-pin version is … Read more
Hello everyone, we are the Low Voltage Industry Network! RS232, RS422, and RS485 have always been common interfaces in the low voltage industry. Many friends have mentioned the differences between them. In this issue, the Low Voltage Industry Network will summarize the main differences, which can be categorized into six aspects. Let’s take a look. … Read more
Overview of RS232 The RS-232 interface complies with the serial data communication interface standard established by the Electronic Industries Alliance (EIA). The original designation is EIA-RS-232 (abbreviated as 232, RS232). It is widely used for connecting computer serial interface peripherals. This includes connection cables as well as mechanical, electrical, signal, and transmission processes. The RS-232-C … Read more
Serial interfaces are primarily used for serial bit-by-bit data transmission, allowing for bidirectional communication with just a pair of transmission lines, which offers the advantages of simple communication lines and low costs. Nowadays, many serial data interfaces are used in specific fields, with common examples including I2C, CAN, LIN, SPI, Flex, MOST, and I2S. Of … Read more

In this article, I will explain the role and application scenarios of serial WiFi modules. WiFi Module 1. Definition: The serial WiFi module is a widely used wireless communication module that … Read more
Bluetooth communication is quite interesting! In simple terms, it allows microcontrollers to chat with mobile phones and communicate with tablets. Beginners often find this quite challenging, but really… it’s just a serial port! Today, we will start from the basics and break down these seemingly advanced technologies. Basic Concepts – Don’t Be Intimidated by Terminology … Read more
UART, or Universal Asynchronous Receiver/Transmitter, is one of the most commonly used communication protocols between devices. When configured correctly, UART can work with many different types of serial protocols that involve sending and receiving serial data. In serial communication, data is transmitted bit by bit over a single line or wire. In bidirectional communication, we … Read more
Hello everyone, I am Da Yi, and today we are going to talk about the serial communication protocol between microcontrollers (MCU) and PLCs. When it comes to serial communication, many of you might feel confused, but don’t worry, I will clarify everything shortly. What is Serial Communication?Communication is everywhere; for example, the way you and … Read more
