What Is An Interrupt Request (IRQ) In Microcontrollers? - Electrical Engineering Essentials

Описание: What Is An Interrupt Request (IRQ) In Microcontrollers? In this informative video, we'll dive into the concept of Interrupt Requests (IRQ) in microcontrollers, a fundamental aspect of how these devices operate efficiently. We'll start by defining what an IRQ is and how it enables microcontrollers to manage multiple events simultaneously. Understanding the role of IRQs is essential for anyone interested in electronics and embedded systems.

We'll discuss the two primary sources of IRQs: external pins and internal peripherals. You'll learn how these requests help microcontrollers respond promptly to important events, such as button presses or data from sensors. Additionally, we’ll explain the function of the interrupt controller and how it prioritizes multiple requests to ensure the processor executes the correct Interrupt Service Routine.

The video will also cover the process of saving the processor's state during an IRQ and the significance of the interrupt vector table in identifying the source of the interrupt. By the end of this discussion, you'll see how IRQs contribute to the smooth operation of embedded systems, particularly in real-time applications.
