WebJul 26, 2015 · EXTI library is used to set GPIO pin as external interrupt. It is designed to easily enable/disable interrupt and handle irq requests. If you don’t know how EXTI works on STM32F4 or STM32F7 lines, you should take a look here. Library Read more about new HAL libraries Features Allows up to 16 external interrupts at a time Allows to setup … Webmy problem: when i press the micro switch i expect that the void HAL_GPIO_EXTI_Callback(ut16 GPIO_Pin) executed two times. one time for rising edge and one time for falling edge. but it is executed three times. also when i press and hold down the micro switch, the callback routine executes repeatedly.

WebIf you want to change the state of your LED on each push button event, you don't need to put a delay in the HAL_GPIO_EXTI_Callback. It's not a good practice in firmware development. IRQs are supposed to manage events quickly. Their processes have a higher priority than the program execution (here, your main). 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. faith evangelical church radcliffe ia
