Struct e310x_hal::spi::SpiSharedDevice

pub struct SpiSharedDevice<'bus, SPI, PINS, CS> { /* private fields */ }

SPI shared device abstraction

Implementations

impl<'bus, SPI, PINS, CS> SpiSharedDevice<'bus, SPI, PINS, CS>where SPI: SpiX, PINS: PinsNoCS<SPI>, CS: PinCS<SPI>,

pub fn new(bus: &'bus SharedBus<SPI, PINS>, cs: CS, config: &SpiConfig) -> Selfwhere PINS: PinsNoCS<SPI>,

Create shared SpiSharedDevice using the existing SharedBus and given SpiConfig. The config gets cloned.

pub fn release(self) -> CS

Releases the CS pin back
