Hello, I would like to contact you because, following the code made on Keil uvision 5, I cannot get my interrupt to work.Objective of the code, turn on and off the LED (pb0) of the card with the button (pc13) on it itself.PCB Used : STM32F767ZI

Hello, I would like to ask you to know how it is that the PA5 pin in OUTPUT (non-pullup and non-pulldown) delivers a voltage of only 2.6 V instead of 3.3 V like the others? Thanks in advance
