Question

What is the difference of UART and USART communication

Answer 1

USART vs UART: Know the difference. ... A USART -- a Universal Synchronous/Asynchronous Receiver/Transmitter -- is a microcontroller peripheral that converts incoming and outgoing bytes of data into a serial bit stream. Hmm. The definition of a USART is identical to that of a UART, but with "synchronous" added to the term.
