Posted on May 17, 2011 at 13:10Hi jschatz Can you paste you configuration for GPIO NVIC and EXTI for that specific port also I found in a lot examples that they always clearing the pending bit I have been using external interrupts for many thing fro...
Posted on May 17, 2011 at 13:10yes you are correct the interrupt should only work on a transition, but from personal experience with the stm32 i know that if an interrupt is set the way yo described and tends to not work properly. in theory what you...
Posted on May 17, 2011 at 13:10you set the interrupt to respond to a rising edge but you said that the actual pin in pulled high this would mean that interrupt is always TRUE therefore why it keeps going back to the interrupt routine, you do clear t...

Posted on May 17, 2011 at 13:03also when you set the alarm dont do this: RTC_SetCounter(0x00015170); RTC_ALR_FLAG = 0x00015170 + 2 ; RTC_SetAlarm((RTC_ALR_FLAG)); since you dont know for sure that the counter is at that value still. of course if you...
