An Embedded System is a purpose-built computing unit designed to carry out specific tasks within a broader electrical or mechanical setup. Unlike general-purpose computers, these systems are fine-tuned for high efficiency, stability, and performance in targeted applications.
Embedded systems often operate in real time, requiring fast and accurate responses to sensor inputs, user interactions, or environmental changes.They typically use microcontrollers, processors, and firmware engineered for low power consumption and stable operation.Due to their compact architecture and high dependability, embedded systems form the foundation of today’s smart technologies and automated solutions.
Common Communication Protocols in Embedded Systems
- I2C / SPI – Used for interfacing sensors, microchips, and peripheral devices.
- UART / USART – Standard protocols for serial data transmission.
- CAN – A robust communication bus commonly used in automotive
- Ethernet / Wi-Fi / BLE – Protocols for wired and wireless networking.
- USB – Enables connection between devices and computers or peripherals.
