communication protocols used in embedded systems

Communication protocols used in embedded systems include:

1. **UART (Universal Asynchronous Receiver/Transmitter)**: Asynchronous serial communication for point-to-point connections.

2. **SPI (Serial Peripheral Interface)**: Synchronous serial communication for high-speed, short-distance communication.

3. **I2C (Inter-Integrated Circuit)**: Synchronous serial communication for multi-device communication on a two-wire bus.

4. **CAN (Controller Area Network)**: Robust protocol for vehicle and industrial communication with multi-master support.

5. **RS-485**: Differential serial communication for long-distance and noisy environments.

6. **Ethernet**: Network protocol for high-speed data communication over local area networks (LANs).
