I must use the funcion pwm o adc to configure the sensor?

thanks

The sensor is :

Level Output detected: High (3.3V)
Level Output undetected Low (0 V)

thanks

I apologize for the lack of clarity are not very practical about this tab

I would like to enable the pin an input to a motion sensor

I would like some sample code to configure this sensor and pin input

thanks

sorry but I do not understand
board.h file to activate the input pin must remove the pullu-up?

and the documentation about pal drivers where can i take?

hello to all

I have a question concerning the stm32f303-discovery
I would like to set up a motion sensor (PIR) with it
I would like to know how I can do and how do I enable pin input

thanks
