I am using STM32F4 micro controller and few GPIO pins i am making as input pins for sensor input staus and few as output pins to activate the LEDs. As soon as i configure few pins as input pins for sensor, few out pins for LED drive stop working, I am confuse, what could be the reason, software or hardware?
