DigitalInOut
– digital input and output¶
A DigitalInOut is used to digitally control I/O pins. For analog control of
a pin, see the AnalogIn
and
AnalogOut
classes.
-
class
digitalio.
DigitalInOut
(pin)¶ Create a new DigitalInOut object associated with the pin. Defaults to input with no pull. Use
switch_to_input()
andswitch_to_output()
to change the direction.Parameters: pin (Pin) – The pin to control -
deinit
()¶ Turn off the DigitalInOut and release the pin for other use.
-
__enter__
()¶ No-op used by Context Managers.
-
__exit__
()¶ Automatically deinitializes the hardware when exiting a context. See Lifetime and ContextManagers for more info.
-
switch_to_output
(value=False, drive_mode=digitalio.DriveMode.PUSH_PULL)¶ Set the drive mode and value and then switch to writing out digital values.
Parameters:
-
switch_to_input
(pull=None)¶ Set the pull and then switch to read in digital values.
Parameters: pull (Pull) – pull configuration for the input Example usage:
import digitalio import board switch = digitalio.DigitalInOut(board.SLIDE_SWITCH) switch.switch_to_input(pull=digitalio.Pull.UP) # Or, after switch_to_input switch.pull = digitalio.Pull.UP print(switch.value)
-
direction
¶ The direction of the pin.
Setting this will use the defaults from the corresponding
switch_to_input()
orswitch_to_output()
method. If you want to set pull, value or drive mode prior to switching, then use those methods instead.
-
value
¶ The digital logic level of the pin.
-
drive_mode
¶ The pin drive mode. One of:
-
pull
¶ The pin pull direction. One of:
Raises: AttributeError – if direction
