Introduction

There are many serial communication protocol as I2C, UART and SPI.

A Universal Asynchronous Receiver/Transmitter (UART) is a block of

circuitry responsible for implementing serial communication.

UART is Full Duplex protocol (data transmission in both directions

simultaneously)

Transmitting UART converts parallel data from the master device (eg.

CPU) into serial form and transmit in serial to receiving UART.

Receiving UART will then convert the serial data back into parallel data

for the receiving device
