Exploring Interrupts and Priorities in STM32F4 Microcontrollers

Join us in this session as we delve into the intricacies of handling multiple interrupts using the STM32F4 microcontroller, based on the Cortex-M architecture. The video demonstrates the practical implementation of interrupts using two LEDs and buttons to highlight how interrupt priorities are managed. Learn how to configure external interrupts, set priorities, enable and disable interrupts, and understand key concepts like pending bits and interrupt lifecycle. This session provides a detailed explanation of using ST's HAL APIs for NVIC controller access, along with real-time code demonstrations and essential tips for optimizing interrupt handling in embedded systems.
