SPI peripheral configuration

Implementations

impl Config

pub fn frequency(&self) -> Rate

The target frequency.

pub fn clock_source(&self) -> ClockSource

Available on crate feature unstable only.

The clock source.

pub fn with_mode(self, mode: Mode) -> Self

Assign the given value to the mode field.

pub fn mode(&self) -> Mode

SPI sample/shift mode.

pub fn with_read_bit_order(self, read_bit_order: BitOrder) -> Self

Assign the given value to the read_bit_order field.

pub fn read_bit_order(&self) -> BitOrder

Bit order of the read data.

pub fn with_write_bit_order(self, write_bit_order: BitOrder) -> Self

Assign the given value to the write_bit_order field.

pub fn write_bit_order(&self) -> BitOrder

Bit order of the written data.

pub fn with_min_async_transfer_size( self, min_async_transfer_size: usize, ) -> Self

Available on crate feature unstable only.

Assign the given value to the min_async_transfer_size field.

pub fn min_async_transfer_size(&self) -> usize

Available on crate feature unstable only.

Minimum transfer size in bytes below which CPU-driven (blocking) I/O is used instead of async or DMA transfers.

This can reduce overhead for small transfers where DMA setup or async context-switch cost exceeds the benefit. For SpiDma, the threshold applies in both blocking and async DMA modes: when met, DMA is disabled and the transfer is performed by the CPU. This applies to both full-duplex and half-duplex transfers.

A value of 0 (the default) disables the threshold — all transfers use the driver’s default method.

impl Config

pub fn with_frequency(self, frequency: Rate) -> Self

Sets the frequency of the SPI bus clock.

The closest available frequency that does not exceed frequency is used, so the bus never runs faster than requested.

pub fn with_clock_source(self, clock_source: ClockSource) -> Self

Available on crate feature unstable only.

Sets the clock source of the SPI bus.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.
