Struct microbit::hal::lpcomp::LpComp

pub struct LpComp { /* fields omitted */ }

A safe wrapper around the LPCOMP peripheral.

Implementations

impl LpComp

pub fn new<P>(lpcomp: LPCOMP, input_pin: &P) -> LpComp where
    P: LpCompInputPin, 

Takes ownership of the LPCOMP peripheral, returning a safe wrapper using specified input pin and a default Vref of Vdd/2.

pub fn vref(&self, vref: VRef) -> &LpComp

Selects comparator Vref.

pub fn aref_pin<P>(&self, ref_pin: &P) -> &LpComp where
    P: LpCompRefPin, 

Sets analog reference pin.

pub fn hysteresis(&self, enabled: bool) -> &LpComp

Enables/disables comparator hysteresis.

pub fn analog_detect(&self, event: Transition) -> &LpComp

Analog detect event configuration, used for analog signal power up from OFF.

pub fn enable_interrupt(&self, event: Transition) -> &LpComp

Enables COMP_LPCOMP interrupt triggering on the specified event.

pub fn disable_interrupt(&self, event: Transition) -> &LpComp

Disables COMP_LPCOMP interrupt triggering on the specified event.

pub fn enable(&self)

Enables the comparator and waits until it’s ready to use.

pub fn disable(&self)

Disables the comparator.

pub fn is_up(&self) -> bool

Checks if the Up transition event has been triggered.

pub fn is_down(&self) -> bool

Checks if the Down transition event has been triggered.

pub fn is_cross(&self) -> bool

Checks if the Cross transition event has been triggered.

pub fn event_up(&self) -> &Reg<u32, _EVENTS_UP>

Returns reference to Up transition event endpoint for PPI.

pub fn event_down(&self) -> &Reg<u32, _EVENTS_DOWN>

Returns reference to Down transition event endpoint for PPI.

pub fn event_cross(&self) -> &Reg<u32, _EVENTS_CROSS>

Returns reference to Cross transition event endpoint for PPI.

pub fn reset_event(&self, event: Transition)

Marks event as handled.

pub fn reset_events(&self)

Marks all events as handled.

pub fn read(&self) -> CompResult

Returns the output state of the comparator.

pub fn free(self) -> LPCOMP

Consumes self and returns back the raw LPCOMP peripheral.
