Hi.I have some problem with Nucleo stm32f030r8.I make a led blinking application.I make porta_0 as output and portb_0 as input and i make portb_0 pull down mode I want that when portb_0 being 1 level porta_0 turn to 1 level and led torn on but i have problem that i always read 1 value from idr for portb_0
It only works when i connect portb_0 to ground then led turns off
I dont know why ?))
