Interfacing

Embedded systems interfacing is the practice of connecting and communicating between an embedded system (often a microcontroller or microprocessor-based device) and other hardware components or external systems.

This allows the embedded system to interact with sensors, actuators, displays, memory devices, communication modules, and other peripherals.

Types of Interfaces:

Digital Interfaces:

Communicate using discrete binary signals (high/low voltage), commonly used in digital I/O pins.

Analog Interfaces:

Handle continuous signals, allowing for sensing and outputting analog signals (e.g., audio or temperature sensors).

Communication Interfaces:

Standardized protocols for data exchange, including I2C, SPI, UART, and CAN.
