Video Overview
This lecture examines serial communication protocols as efficient alternatives to parallel communication. Learn how serial systems offer simpler wiring and reduced costs, making them ideal for embedded applications. We explore UART (Universal Asynchronous Receiver/Transmitter), SPI (Serial Peripheral Interface), and I²C (Inter-Integrated Circuit), discussing their key features, benefits, limitations, and typical use cases. The session concludes with a brief look at the high-speed Universal Serial Bus (USB), highlighting its relevance in modern embedded systems.
