Struct kernel::hil::spi::cs::ChipSelectPolar

pub struct ChipSelectPolar<'a, P: Output> {
    pub pin: &'a P,
    pub polarity: Polarity,
}

A convenience wrapper type around Output GPIO pins that implements IntoChipSelect for both ActiveLow and ActiveHigh.

Fields

pin: &'a P

The underlying chip select “pin”.

polarity: Polarity

The polarity from which this wrapper was derived using IntoChipSelect.

Implementations

impl<'a, P: Output> ChipSelectPolar<'a, P>

When wrapping a GPIO pin that implements gpio::Output, users can use the activate and deactivate methods to automatically set or clear the chip select pin based on the stored polarity.

pub fn deactivate(&self)

Deactivate the chip select pin.

High if active low, low if active high.

pub fn activate(&self)

Active the chip select pin.

Low if active low, high if active high.

Trait Implementations

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
