Introduction to Zephyr Part 9: Interrupts, Timers, and Counters

This 56-minute video tutorial from Digi-Key explores the critical concepts of interrupts, timers, and counters in Zephyr RTOS for embedded development. Discover how interrupts enable systems to respond instantly to events, learn to write efficient Interrupt Service Routines (ISRs), and understand time-sensitive operations implementation. Compare software-based timers using the kernel's internal clock with hardware-based counters offering microsecond precision. Master GPIO interrupt configuration for external events like button presses, including solutions for common challenges such as button debounce. Learn how workqueues allow deferring complex operations from ISRs to thread-based contexts, keeping interrupt handlers lightweight while maintaining system responsiveness. The tutorial includes practical demonstrations with code examples, supported by a GitHub repository and additional written explanations. Perfect for embedded developers working on IoT devices, motor control systems, or edge AI projects seeking to build efficient real-time applications with Zephyr RTOS.
