Transmission speeds vary dramatically, from the typical 9600 baud setting to 115200 and beyond. This speed is known as the baud rate, expressed in bits per second, or bps. This ends a packet.ДЄs an asynchronous protocol- no clock line regulates data transmission speed- users must set both devices to communicate at the same speed. Finally, one or more stop bits are transmitted where the line is set to high. After the start bit, five to nine data bits transmit in what is known as the packetвЂ™s data frame, followed by an optional parity bit to verify proper data transmission. Half duplex : Data flows in one direction at a timeДata transmission takes place in the form of data packets, beginning with a start bit, where the ordinarily high line is pulled to ground. Full duplex : Simultaneous communication to and from each master and slave UARTs transmit data serially, in one of three modes: The second UART receives this data on its Rx pin and transforms it back into parallel to communicate with its controlling device.

When sending on the Tx pin, the first UART translates this parallel information into serial and transmits it to the receiving counterpart.Д¤. Data travels to and from a UART in parallel to the controlling device (e.g., a CPU).ДЈ. UART is a single-master, single-slave protocol, where one device is set up to communicate with only one partner.Дў. Commonly, the transmission will take place at 3.3 or 5V. One chipвЂ™s Tx (transmit) pin connects directly to the otherвЂ™s Rx (receive) pin and vice versa. UART was adapted into single-chip units in the early 1970s, starting with Western DigitalвЂ™s WD1402A.ДЎ. As a вЂњuniversalвЂќ setup, we can configure UART to work with many different types of serial protocols.
