UART
Universal Asynchronous Receiver/Transmitter (Universal Asynchronous Receiver/Transmitter, usually called UART ) is a serial asynchronous receiving and sending protocol, which is widely used. The working principle of UART is to transmit the binary bits of data bit by bit. In the UART communication protocol, the high level of the status bit on the signal line represents '1' and the low level represents '0'. Of course, when two devices use UART serial communication, you must first agree on the transmission rate and some data bits.
In the process of software testing, if you need to capture the serial port log, UART is a commonly used tool. This article is just a concept popularization. If you purchase related equipment, you can search on Taobao. Keyword: UART
