Struct embedded_hal_async::spi::ExclusiveDevice

pub struct ExclusiveDevice<BUS, CS> { /* private fields */ }

SpiDevice implementation with exclusive access to the bus (not shared).

This is the most straightforward way of obtaining an SpiDevice from an SpiBus, ideal for when no sharing is required (only one SPI device is present on the bus).

Implementations

impl<BUS, CS> ExclusiveDevice<BUS, CS>

pub fn new(bus: BUS, cs: CS) -> Self

Create a new ExclusiveDevice
