UARTs & USARTs

⁠

UART is a hardware device or microchip that translates data between parallel and serial forms. It is used for asynchronous communication, meaning it doesn't require a clock signal to synchronize the output of bits from the transmitting UART to the sampling of bits by the receiving UART. Instead, the sender and receiver agree on a baud rate (bits per second) before communication begins. UARTs are commonly used in applications like GPS receivers, Bluetooth modules, and wireless radio frequency modules.

USART is similar to UART, but it can also operate synchronously. In synchronous mode, data transfer is synchronized by a clock signal generated by the USART hardware. This allows for higher data rates than asynchronous communication as it eliminates the need for start and stop bits. USARTs are often used in applications that require high-speed wired communication. Both UART and USART require careful configuration of parameters like baud rate, parity, stop bits, and data length. The specific configuration depends on the requirements of the devices being connected.
