UART
📡🔬 Exploring the World of UART in Embedded Systems! 🎛️💡
In the realm of embedded systems, communication is key. One of the most popular methods of serial communication is through UART - Universal Asynchronous Receiver/Transmitter. UARTs facilitate communication between devices, such as microcontrollers, computers, and other peripheral devices, making them a fundamental component in embedded systems. 🌐🤝
UART is versatile and straightforward, enabling the transmission and reception of data over a serial link. Let's take a closer look at its main features:
1️⃣ Asynchronous Communication: With UART, data is transmitted asynchronously, meaning there is no clock signal to synchronize the output of bits from the transmitting UART to the sampling of bits by the receiving UART. Instead, both sides agree on a data rate beforehand.
2️⃣ Data Frame Structure: A UART data frame consists of a start bit, data bits, an optional parity bit, and stop bits. This structure ensures data integrity and detection of communication errors.
3️⃣ Baud Rate: The speed of data transmission in UART is specified by the baud rate - the number of bits transmitted per second.
4️⃣ Hardware Independence: UART communication can occur between devices with different hardware architectures, making it a versatile choice for various applications.
