Introduction to UART

by
Introduction to UART

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
