WebJul 15, 2024 · The HAL_GPIO_EXTI_IRQHandler()implementation clears the pending bit in the peripheral, not in the NVIC. If it didn't clear the pending bit by calling __HAL_GPIO_EXTI_CLEAR_IT(GPIO_Pin), then the handler would be called again and again. Webpic10f • 1 yr. ago. The use of a callback separates the job of handling the interrupt itself (recognizing that it occurred and clearing any interrupt-specific flags) and the function handler that matters to the application (like setting a flag or putting a data byte into a queue). It allows the application designer (you) to create the handler ...
