PROGRESS 3: INTRODUCTION

Before I get started with this project, I had done some researches about the Universal Asynchronous Receiver/ Transmitter to get overview for more understanding.

A Universal Asynchronous Receiver/Transmitter is a piece of computer hardware that translates data between parallel and serial forms. UARTs are commonly used in conjunction with communication standards such as EIA, RS-232, RS-422 or RS-485. The universal designation indicates that the data format and transmission speeds are configurable. The electric signaling levels and methods such as differential signaling are handled by a driver circuit external to the UART. A UART is usually an individual (or part of an) integrated circuit used for serial communications over a computer or peripheral device serial port. UARTs are now commonly included in microcontrollers. A dual UART, or DUART, combines two UARTs into a single chip. Many modern ICs now come with a UART that can also communicate synchronously these devices are called USARTs (Universal Synchronous/Asynchronous Receiver/ Transmitter).
