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

Welcome to Lecture 38 of the course "Embedded C Programming" by Prof. Nitin Chandrachoodan. Full Course: https://study.iitm.ac.in/es/course_pa... 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. About IIT Madras' online Bachelor of Science programme IIT Madras offers four-year BS programmes that aim to provide quality education to all, irrespective of age, educational background, or location. The BS programme has multiple levels, which provide flexibility to students to exit at any of these levels. Depending on the courses completed and credits earned, the learner can receive a Foundation Certificate from IITM CODE (Centre for Outreach and Digital Education), Diploma(s) from IIT Madras, or BSc/BS Degrees from IIT Madras.
