: Standard methods like UART, SPI, and I2C for data exchange between chips.

: Components like temperature sensors for input and motors or LEDs for output.

Embedded programming requires a focus on efficiency and direct hardware control. How to Get Started Learning Embedded Systems

: Essential for interacting with the physical world, including: I/O Ports (GPIO) : For basic digital signals.

: Includes power sources, clock oscillators, and reset circuits. 2. Software & Programming Essentials

Embedded systems are specialised computing systems that perform dedicated functions within larger mechanical or electrical systems. They combine custom hardware with tightly coupled software to operate efficiently under constraints like low power and real-time performance. 1. Core Hardware Components

: Popular choices for beginners include Arduino (ATmega), ESP32 , and STM32 (ARM Cortex-M).

At the heart of an embedded system is the or Microprocessor (MPU) .
