Here are some interview questions and answers related to UART (Universal Asynchronous Receiver-Transmitter):
- What is UART? UART stands for Universal Asynchronous Receiver-Transmitter. It’s a hardware component used for serial communication, commonly found in microcontrollers, communication peripherals, and other embedded systems.
- How does UART differ from other communication protocols like SPI and I2C?
UART is asynchronous, meaning it doesn’t require a clock signal to transmit data. SPI (Serial Peripheral Interface) and I2C (Inter-Integrated Circuit) are synchronous protocols and require a clock signal. Additionally, UART typically involves only two lines (TX and RX) for communication, while SPI and I2C can involve multiple lines.
