Now it's possible to construct outputs or enable pulls immediately: ```py >>> d = digitalio.DigitalInOut(board.A0, pull=digitalio.Pull.UP) >>> d.pull digitalio.Pull.UP ``` ```py >>> d = digitalio.DigitalInOut(board.A0, value=True) >>> d.direction digitalio.Direction.OUTPUT >>> d.value True ``` ```py >>> d = digitalio.DigitalInOut(board.A0, value=False, drive_mode=digitalio.DriveMode.OPEN_DRAIN) >>> d.drive_mode digitalio.DriveMode.OPEN_DRAIN ``` The finaliser means that if a pin object is allowed to go out of scope, then it will be deinitialized automatically when GC runs. **this is a potential incompatibility**: some hypothetical code that intentionally leaked a pin might function differently, i.e. ```py digitalio.DigitalInOut(board.A0).switch_to_output(True) ``` as a way to stick a pin in output mode indefinitely will no longer work (but may still appear to work "for awhile" because gc doesn't run right away). I made this change in part because it simplifies error handling in the constructor: An incorrect argument would otherwise have left the pin stuck in allocated state until the interpreter was reset; with this change, it's available again though not until the GC runs so it would remain perplexing in interactive situations: ```py >>> d = digitalio.DigitalInOut(board.A0, pull=7) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: pull must be of type Pull or None, not int >>> d = digitalio.DigitalInOut(board.A0) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: A0 in use >>> gc.collect() >>> d = digitalio.DigitalInOut(board.A0) >>> d <DigitalInOut> ``` |
