Struct SpiDeviceWithConfig

pub struct SpiDeviceWithConfig<'a, M: RawMutex, BUS: SetConfig, CS> { /* private fields */ }

SPI device on a shared bus, with its own configuration.

This is like SpiDevice, with an additional bus configuration that’s applied to the bus before each use using SetConfig. This allows different devices on the same bus to use different communication settings.

Implementations

impl<'a, M: RawMutex, BUS: SetConfig, CS> SpiDeviceWithConfig<'a, M, BUS, CS>

pub fn new(bus: &'a Mutex<M, BUS>, cs: CS, config: BUS::Config) -> Self

Create a new SpiDeviceWithConfig.

pub fn set_config(&mut self, config: BUS::Config)

Change the device’s config at runtime

where BUS: ErrorType + SetConfig, CS: OutputPin, M: RawMutex,

type Error = SpiDeviceError<<BUS as ErrorType>::Error, <CS as ErrorType>::Error>

Error type.
