It is designed in different ways based on system requirements, and these protocols have a specific rule agreed upon between devices to achieve successful communication.Р вЂќР’В®mbedded systems, microcontrollers, and computers mostly use UART as a form of device-to-device hardware communication protocol. Р Р†Р вЂљРЎС™The single biggest problem in communication is the illusion that it has taken place.Р Р†Р вЂљРЎСљР вЂќР’В¬ommunication protocol plays a big role in organizing communication between devices. During product development, this document also aims to share some basic steps when checking on a data sheet for actual usage.Р вЂќР вЂћt the end of the article, the goal is for better understanding and compliance of UART standards to maximize the capabilities and application, particularly when developing new products.

In this article, we will discuss the fundamental principles when using UART, with a focus on packet transmission, standard frame protocol, and customized frame protocols that are value added features for security compliance when implemented, especially during code development. Depending on the application and system requirements, serial communications needs less circuitry and wires, which reduces the cost of implementation. In two-way communication, we use two wires for successful serial data transfer. In serial communication, data is transferred bit by bit using a single line or wire. When properly configured, UART can work with many different types of serial protocols that involve transmitting and receiving serial data.

This article shows how to use UART as a hardware communication protocol by following the standard procedure. UART, or universal asynchronous receiver-transmitter, is one of the most used device-to-device communication protocols.
