Fun and Easy UART - How the UART Protocol Works
•
1 recomendación•856 vistas
Learn how the UART Protocol works. A universal asynchronous receiver/transmitter is a computer hardware device for asynchronous serial communication in which the data format and transmission speeds are configurable. The electric signaling levels and methods (such as differential signaling, etc.) are handled by a driver circuit external to the UART.
