The UART (Universal Asynchronous Receiver/Transmitter) is a serial communication device that serves as a bidirectional, serial, asynchronous communication bus. It can achieve full-duplex communication using one data receiving line (RX), one data transmitting line (TX), and a ground line (GND). As shown in the figure below: When communicating using UART, the unit of transmission is … Read more
6. Serial Interface Parallel Communication and Serial Communication Asynchronous and Synchronous Communication Asynchronous Serial Full Duplex (P3.0-RXD P3.1-TXD) Timer 1 serves as the baud rate generator to control the rhythm of opening the door, generating transmission and reception completion interrupts TI, RI Mode 0 is used for expanding IO, while Modes 1-2 are communication modes. … Read more

Background Introduction In embedded systems, UART serial ports are commonly used for debugging and communication. Typically, there are no specific requirements for the baud rate of the debugging serial port, with a common configuration being 115200 8N1. Besides debugging, UART serial ports can also serve as data communication interfaces for interconnecting with other boards or … Read more
Click the blue text above to follow us Embedded Training – Choose Jufeng Smart Link 1. Definition UART (Universal Asynchronous Receiver/Transmitter) is a widely used serial communication protocol for transmitting data asynchronously between devices. It does not require a shared clock signal but relies on pre-agreed parameters (such as baud rate) for communication. Functions and … Read more
Your device connects to another device, and if it can automatically recognize the baud rate without knowing the baud rate of the other device, wouldn’t that be very convenient? 1 Overview Regarding the issue of automatically recognizing UART serial port baud rates, those with project experience or who have studied serial ports should know a … Read more
