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 callback function by adding the … WebWell, HAL delay relies on a variable that is incremented in the SysTick interrupt. If the EXTI interrupt is a higher priority, then that variable would never get incremented. Edit: pretty sure the timeout parameter works the same way so it probably isn’t working either, not that it probably matters.
