window watchdog in stm32f103

Posted on September 02, 2015 at 22:29

hi every one

I'm trying to initial stm32f103rbt6's window watchdog with keil cmsis examples,

every thing is OK but in reverse direction,i mean it seems external interrupt & wwdg interrupt handlers are act instead of each others.

based on keil read me descriptions periodically it must update wwdg counter & blink leds except when i pulled down portb.9(then wwdg must reset mcu)

but know exti interrupt handler act normally & when i pulled down exti then wwdg handler act.

i am completely mixed up,hope to any body guide me,i attached my project in keil too

with best regards.

#stm32f1 #iwdg-wwdg
