Struct rppal::gpio::Pin [−][src]
pub struct Pin { /* fields omitted */ }
Expand description
Unconfigured GPIO pin.
Pin
s are constructed by retrieving them using Gpio::get
.
An unconfigured Pin
can be used to read the pin’s mode and logic level.
Converting the Pin
to an InputPin
, OutputPin
or IoPin
through the
various into_
methods available on Pin
configures the appropriate mode, and
provides access to additional methods relevant to the selected pin mode.
The unproven
embedded-hal
digital::InputPin
trait implementation for Pin
can be enabled
by specifying the optional hal-unproven
feature in the dependency declaration for
the rppal
crate.
Implementations
Returns the GPIO pin number.
Pins are addressed by their BCM numbers, rather than their physical location.
Consumes the Pin
and returns an InputPin
. Sets the mode to Input
and enables the pin’s built-in pull-down resistor.
The pull-down resistor is disabled when InputPin
goes out of scope if reset_on_drop
is set to true
(default).
Consumes the Pin
and returns an InputPin
. Sets the mode to Input
and enables the pin’s built-in pull-up resistor.
The pull-up resistor is disabled when InputPin
goes out of scope if reset_on_drop
is set to true
(default).
Consumes the Pin
and returns an OutputPin
. Sets the mode to Mode::Output
and leaves the logic level unchanged.
Consumes the Pin
and returns an OutputPin
. Changes the logic level to
Level::Low
and then sets the mode to Mode::Output
.
Consumes the Pin
and returns an OutputPin
. Changes the logic level to
Level::High
and then sets the mode to Mode::Output
.
