▲Click the card above to follow and learn more▲ Communication issues, like traffic problems, can vary in speed, congestion, and interruptions. If we compare serial communication to traffic, UART can be likened to a station, and a frame of data is akin to a car. Cars on the road must obey traffic rules. In the … Read more
SPI (Serial Peripheral Interface) SPI is a high-speed, full-duplex, synchronous, serial communication bus with a 3-4 wire interface, operating in a master-slave mode, allowing multiple SPI devices to be interconnected. The SPI device that provides the SPI serial clock is the SPI master, while other devices are the SPI slaves. The SPI bus consists of … Read more
Look at the image below; you probably guessed that today’s protagonist is UART. The serial port we commonly refer to includes both TTL level and RS-232 level, and in embedded systems, the serial port of microcontrollers is usually TTL level. Today’s content is about the frame format of UART, which is quite simple; those who … Read more

1. What is UART? As one of the three commonly used low-speed buses (UART, SPI, IIC), UART plays an important role in designing various communication interfaces and debugging. UART stands for Universal Asynchronous Receiver/Transmitter, which is mainly used for serial data transmission, and operates in a full-duplex mode. When sending data, it converts parallel data … Read more
UART stands for Universal Asynchronous Receiver/Transmitter, also known as serial communication. Unlike communication protocols like SPI and I2C, it is a physical circuit within microcontrollers or an independent IC. The main purpose of UART is to send and receive serial data, and its greatest advantage is that it uses only two wires to transmit data … Read more
UART (Universal Asynchronous Receiver/Transmitter) is a widely used serial communication protocol in embedded systems. It supports full-duplex communication, allowing simultaneous data transmission and reception, making it very useful in applications that require bidirectional communication. The working principle of UART is to transmit data bit by bit, meaning each binary bit is transmitted independently through signal … Read more
