Struct Flex

pub struct Flex<'d> { /* private fields */ }

Expand description

GPIO flexible pin.

This pin can be either an input or output pin. The output level register bit will remain set while not in output mode, so the pin’s level will be ‘remembered’ when it is not in output mode.

Implementations§

impl<'d> Flex<'d>

pub fn new(pin: impl Peripheral<P = impl Pin> + 'd) -> Self

Wrap the pin in a Flex.

The pin remains disconnected. The initial output level is unspecified, but can be changed before the pin is put into output mode.

pub fn set_pull(&mut self, pull: Pull)

Set the pin’s pull.

pub fn set_drive_strength(&mut self, strength: Drive)

Set the pin’s drive strength.

pub fn set_slew_rate(&mut self, slew_rate: SlewRate)

Set the pin’s slew rate.

pub fn set_schmitt(&mut self, enable: bool)

Set the pin’s Schmitt trigger.

pub fn set_as_input(&mut self)

Put the pin into input mode.

The pull setting is left unchanged.

pub fn set_as_output(&mut self)

Put the pin into output mode.

The pin level will be whatever was set before (or low by default). If you want it to begin at a specific level, call set_high/set_low on the pin first.

pub fn toggle_set_as_output(&mut self)

Toggle output pin.

pub fn is_high(&self) -> bool

Get whether the pin input level is high.

pub fn is_low(&self) -> bool

Get whether the pin input level is low.

pub fn get_level(&self) -> Level

Returns current pin level

pub fn set_high(&mut self)

Set the output as high.

pub fn set_low(&mut self)

Set the output as low.

pub fn set_level(&mut self, level: Level)

Set the output level.

pub fn is_set_high(&self) -> bool

Is the output level high?

pub fn is_set_low(&self) -> bool

Is the output level low?

pub fn get_output_level(&self) -> Level

What level output is set to

pub fn toggle(&mut self)

Toggle pin output

pub async fn wait_for_high(&mut self)

Wait until the pin is high. If it is already high, return immediately.

pub async fn wait_for_low(&mut self)

Wait until the pin is low. If it is already low, return immediately.

pub async fn wait_for_rising_edge(&mut self)

Wait for the pin to undergo a transition from low to high.

pub async fn wait_for_falling_edge(&mut self)

Wait for the pin to undergo a transition from high to low.

pub async fn wait_for_any_edge(&mut self)

Wait for the pin to undergo any transition, i.e low to high OR high to low.

pub fn dormant_wake(&mut self, cfg: DormantWakeConfig) -> DormantWake<'_>

Configure dormant wake.
