Every time your function is called, you start out with button_value of 0. You may need a global variable that starts out as False (or 0), and once flipped to True (or 1) and then stays there: button_value = False # or: button_value = 0 def button(): global button_value pushbutton = bus.read_byte_data( address, GPIOB ) if pushbutton > 0: button_value = True # or: button_value = 1 return button_value Also I think I'd probably pass the IO address as a parameter to the button function. -- Denis McMahon, denismfmcma...@gmail.com -- https://mail.python.org/mailman/listinfo/python-list
