About this video:
In this video, we explore the concept of interrupt priority levels in the ARM Cortex-M architecture, focusing on how they are managed through the NVIC (Nested Vectored Interrupt Controller) registers. You'll learn how priority bits are structured, what priority grouping means, and how it affects interrupt preemption and sub-priority behavior.
We conclude with a practical demonstration running on an STM32 microcontroller, using Keil-MDK to show real-time configuration and behavior of interrupt priorities in action.
