Struct SpiRegisters 

pub struct SpiRegisters<SPI> { /* private fields */ }

A register map behind an SPI chip select, in the Bosch framing.

The first byte of every transfer is the control byte: the register address with bit 7 set to read or cleared to write. On a read the part then streams consecutive registers; on a write the value follows. The part accepts SPI modes 0 and 3.

Implementations

impl<SPI> SpiRegisters<SPI>

pub fn new(device: SPI) -> SpiRegisters<SPI>

Wraps an SPI device, which is the bus plus the part’s chip-select line.

Arguments

• device - the SPI device.

Returns

The register map.

pub fn release(self) -> SPI

Gives back the device.

Returns

The device the map was built from.

Trait Implementations

impl<SPI: Debug> Debug for SpiRegisters<SPI>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<SPI: SpiDevice> RegisterBus for SpiRegisters<SPI>

type Error = <SPI as ErrorType>::Error

The error the bus underneath reports.

fn read_registers( &mut self, first: u8, buffer: &mut [u8], ) -> Result<(), Self::Error>

Reads consecutive registers starting at first, as many as buffer holds.

fn write_register(&mut self, register: u8, value: u8) -> Result<(), Self::Error>

Writes one register.

fn read_register(&mut self, register: u8) -> Result<u8, Self::Error>

Reads one register.
