Interview Questions – UART

“In an interview, questions are the bridges between a candidate’s experiences and an employer’s expectations. They pave the way for understanding, insight, and the journey towards finding the perfect professional match. Before entering into UART interview questions, it is suggested to go through the UART protocol tutorial at least once. UART, or Universal Asynchronous Receiver-Transmitter, is a communication protocol used for serial communication between devices. It involves the transmission of data between devices bit by bit, without a shared clock signal.

UART

UART is commonly employed in various applications, serving functions such as connecting microcontrollers to other peripherals, facilitating communication between embedded systems, and interfacing with sensors and other hardware components. Moreover, its versatility extends across a spectrum of use cases. Additionally, this adaptability positions UART as an integral component in diverse fields, showcasing its significance in fostering seamless communication within a wide range of electronic systems

The protocol defines the format of the data being sent, including start and stop bits, data bits, and optional parity for error checking. Additionally, UART provides a simple and versatile method for devices to exchange information serially. Moreover, this inherent flexibility and ease of implementation make it a widely adopted communication standard in various applications, ranging from microcontroller communication to data logging and industrial automation.
