I am quiet new to STM32 programming and can't get the external interrupt to work.I started with the NUCLEO-L011K4 and wrote my programm without any issues. I switched to my own board (pdf included) and weren't able to get extrenal interrupts to work....

I manually sodered a 10k pull-down resistor between PB6 and GND but Change_Pin is still constantly reporting 64 instead of 0.

Signal directly on PB6 after phototransistor.

VDD of 3,3V is present at all times. I measure 0V on the pin when the programm is loaded on the MCC. Before the programm is transfered I measure 3V on PB6.

I already tried it with the GPIO_InitStruct.Pull = GPIO_PULLDOWN; and without but it didnt make any difference.
