L38: Interrupts in real-time operating systems (RTOS)

Welcome to Lecture 38 of the course “Embedded C Programming” by Prof. Nitin Chandrachoodan.

Video Overview
This lecture explains how Real-Time Operating Systems (RTOS) manage interrupts to efficiently handle external events and task execution. Learn about deferred interrupt handling, where Interrupt Service Routines (ISRs) respond instantly to interrupts and delegate longer processing to background tasks using semaphores, queues, and notifications. A practical FreeRTOS example on Arduino demonstrates how interrupts, sensor data, and tasks integrate seamlessly in real-world embedded applications, showcasing effective synchronization and event-driven design.
