For engineers working with microcontrollers, especially those using the 8051 series, the question often arises when discussing RTOS: “Why use RTOS? With such limited resources in microcontrollers, can RTOS ensure efficiency?” In response to this question, I would counter: “What is your purpose in using a microcontroller? Is it to program in C, assembly, or … Read more

Click the blue text Follow us 1. Introduction to Serial Communication Protocol The concept of serial communication is very simple; it is a method of communication that sends and receives bytes bit by bit. Although serial communication is slower than parallel communication, which transmits data by bytes, it can achieve data transmission using only two … Read more
A serial port (COM port) is a general term, UART is a protocol, and TTL/RS-232/RS-485 are voltage standards. Data using the UART protocol is transmitted through TTL (board-level short distance), RS-232 (± voltage anti-interference), or RS-485 (differential long distance multi-device) voltage standards, while COM port is the name given by Windows to this type of … Read more
