Struct nrf52832_hal::qdec::Qdec

pub struct Qdec { /* fields omitted */ }

A safe wrapper around the QDEC peripheral with associated pins.

Implementations

impl Qdec

pub fn new(
    qdec: QDEC,
    pin_a: Pin<Input<PullUp>>,
    pin_b: Pin<Input<PullUp>>,
    pin_led: Option<Pin<Input<PullUp>>>,
    sample_period: SamplePeriod
) -> Qdec

Takes ownership of the QDEC peripheral and associated pins, returning a safe wrapper.

pub fn debounce(&self, enable: bool) -> &Qdec

Enables/disables input debounce filters.

pub fn led_polarity(&self, polarity: LedPolarity) -> &Qdec

LED output pin polarity.

pub fn led_pre(&self, usecs: u16) -> &Qdec

Time period the LED is switched ON prior to sampling (0..511 us).

pub fn reset_events(&self)

Marks the interrupt trigger event as handled.

pub fn enable_interrupt(&self, num_samples: NumSamples) -> &Qdec

Triggers the QDEC interrupt on the specified number of non-zero samples.

pub fn disable_interrupt(&self) -> &Qdec

Disables the QDEC interrupt triggering.

pub fn enable(&self)

Enables the quadrature decoder.

pub fn disable(&self)

Disables the quadrature decoder.

pub fn read(&self) -> i16

Returns the accumulated change since last read (-1024..1023).

pub fn free(
    self
) -> (QDEC, Pin<Input<PullUp>>, Pin<Input<PullUp>>, Option<Pin<Input<PullUp>>>)

Consumes self and returns back the raw QDEC peripheral.
