CFR-50JB-52-18R UARTs (Universal Asynchronous Receiver Transmitter) highlighting the core functional technology articles and application development cases of UARTs (Universal Asynchronous Receiver Transmitter) that are effective.
Overview of UART (Universal Asynchronous Receiver Transmitter)UART (Universal Asynchronous Receiver Transmitter) is a widely used hardware communication protocol that facilitates asynchronous serial communication between devices. It is particularly prevalent in embedded systems, microcontrollers, and various electronic devices for data transmission. The core functionalities of UART include:
1. Asynchronous Communication UART operates without a clock signal for synchronization, allowing for simpler and more flexible point-to-point communication.2. Data Framing Data is transmitted in frames, typically consisting of a start bit, data bits, an optional parity bit, and one or more stop bits.3. Baud Rate The speed of data transmission is defined by the baud rate, which indicates the number of signal changes per second. Common baud rates include 9600, 115200, and others.4. Full-Duplex Communication UART supports simultaneous sending and receiving of data, enhancing communication efficiency.5. Error Detection Simple error detection mechanisms, such as parity bits, can be implemented to ensure data integrity.1. Data Transmission and Reception2. Interrupt-Driven Communication3.
