Interrupts Vs Polling: Efficient Event Handling In Embedded Systems
Interrupts handle high-priority tasks while callbacks execute code after events occur. They differ in purpose but often used together in embedded systems.
Introduction In embedded systems, responsiveness and efficiency are crucial for the smooth operation of real-time applications. Whether it’s processing sensor data, managing communication protocols, or handling time-sensitive tasks, the system needs to react promptly to external stimuli. This is where interrupts and callbacks come into play. Both mechanisms are essential for improving the responsiveness of embedded systems by enabling event-driven programming, reducing latency, and enhancing overall system efficiency. This article will explore interrupts and callbacks in embedded systems, thei...
