485 Communication Automatic Transceiving Circuit – The Most Detailed Explanation in History (Click to read) 5 Methods for Switching RS-485 Direction and Their Advantages and Disadvantages Analysis (ClickRead) [Guide] Hello everyone, I am Yijun. In the previous article, I summarized the industrial HART bus. Today, let’s talk about the RS-485 bus. RS-485 is also a … Read more
Communication issues, just like traffic problems, can have various situations such as high-speed, low-speed, congestion, interruptions, etc. If we compare serial communication to traffic, UART can be likened to a station, while a frame of data is similar to a car. Cars on the road must obey traffic rules. In urban areas, speed limits are … Read more
During debugging, various interfaces and conversion boards are encountered, and the feeling of not fully understanding can be quite frustrating! First, serial ports, UART ports, COM ports, and USB ports refer to physical interface forms (hardware). TTL, RS-232, and RS-485 refer to level standards (electrical signals). Serial Port: The term serial port is a general … Read more

1. History of Serial Ports First of all, the serial port is an essential tool for anyone working with hardware and embedded software, especially when debugging a system with an MCU or CPU. Generally, the first thing we do during debugging is to light up the GPIO, and the second is to establish a communication … Read more
