What are communication protocol used in embedded devices communication?

Question

Accepted Answer

Communication protocols used in embedded devices include SPI, I2C, UART, CAN, Ethernet, and Bluetooth.

SPI (Serial Peripheral Interface) is a synchronous serial communication protocol used for short distance communication between microcontrollers and peripheral devices.
I2C (Inter-Integrated Circuit) is a synchronous serial communication protocol used for communication between integrated circuits on a circuit board.
UART (Universal Asynchronous Receiver/Transmitter) is an asynchronous serial communication protocol used for short distance communication between microcontrollers and peripheral devices.
CAN (Controller Area Network) is a serial communication protocol used for communication between microcontrollers and devices in a vehicle or industrial automation system.
Ethernet is a wired networking protocol used for communication between embedded devices and other devices on a network.
Bluetooth is a wireless communication protocol used for short distance communication between embedded devices and other devices.
