Hal_gpio_exti_clear_it

WebThe GPIO external interrupt handle function can clear the interrupt flag, and call the interrupt to callback the function HAL_GPIO_EXTI_Callback(). We only need to refactor the interrupt … http://www.iotword.com/9356.html

Why to clear the interrupt flag before the user callback function?

The EXTI (EXTernal Interrupt/Event) controller consists of up to 40 edge detectors for generating event/interrupt requests on STM32L47x/L48x devices. Each input line can be independently configured to select the type (interrupt or event) and the corresponding trigger event (rising, falling, or both).

WebHAL 库提供了一个定时器中断公共处理函数 HAL_TIM_IRQHandler，该函数又会调用HAL_TIM_PeriodElapsedCallback 等一些回调函数，需要用户根据中断类型选择重定义对应的中 断回调函数来处理中断程序。 注意： 1、中断处理最好写在回调函数里面。 WebMay 29, 2024 · As far as I'm aware, simply overriding the HAL_GPIO_EXTI_Callback function is the way to handle an interrupt, but the pin never toggles. What am I missing here? In STOP mode I believe I should simply place the CPU into STOP mode once and do any processing in an ISR as opposed to, for example, a state machine?
