Communication Protocols are a set of rules that allow two or more communication systems to communicate data via any physical medium. The rules, regulations, synchronization between communication systems, syntax to be followed and semantics are all defined by the term protocol.
Embedded communication protocols have different characteristics which differentiate them: Asynchronous / Synchronous : In a synchronous communication protocol, sender and receive share a common clock.
Jan 20, 2021 · UART in embedded system. Embedded systems, microcontrollers, and computers mostly use a UART as a form of device-to-device hardware communication protocol. Among the available communication protocols, a UART uses only two wires for its transmitting and receiving ends.
Mar 6, 2024 · Communication protocols in embedded systems are essential for enabling devices to exchange data efficiently. They ensure seamless communication between components such as microcontrollers, sensors,...
Jan 6, 2020 · Communication protocols such as UART, SPI, and I2C provide an essential function in embedded systems. They function as an interface between a microcontroller and a peripheral to allow the devices to communicate with each other and the external world.
What is a communication protocol? “A set of formal rules describing how to exchange data.” “Low-level protocols define the electrical and physical standards to be observed, bit- and byte-ordering and the transmission and error detection and correction of the bit stream.”
Communication protocols play a crucial role in enabling data exchange between different components in embedded systems. Three commonly used protocols are UART (Universal Asynchronous Receiver-Transmitter), SPI (Serial Peripheral Interface), and I2C (Inter-Integrated Circuit).
