USART in Arduino
Introduction
USART
(Universal Serial Asynchronous Receiver Transmitter) is a serial
communication protocol used to transmit/receive data serially at a
specific baud rate.
UART Communication Protocol
UART (Universal Asynchronous Transmitter Receiver), this is the most common protocol used for full duplex serial communication. It is a single LSI (large scale integration) chip designed to...
RS232 Protocol
Historically, RS232 Communication protocol is an old serial communication protocol developed by EIA (Electronics Industry Alliance)/TIA (Telecommunications Industry Association)-232 in the year 1962. Modern hardware designs...
