Struct SubghzSpi 

pub struct SubghzSpi<'d, M: Mode> { /* private fields */ }

Sub-GHz radio SPI interface driver.

Wraps the internal SUBGHZSPI peripheral and hardware slave-select line (PWR_SUBGHZSPICR.NSS). Implements embedded-hal and embedded-hal-async SpiDevice traits.

Implementations

impl<'d, M: Mode> SubghzSpi<'d, M>

pub fn set_nss(level: bool)

Control the Sub-GHz radio SPI NSS (slave select) signal.

• false: NSS low (asserted / active).
• true: NSS high (deasserted / inactive).

pub fn nss() -> bool

Read the current state of the Sub-GHz radio SPI NSS signal.

impl<'d> SubghzSpi<'d, Async>

pub fn new<T: Instance, D1: TxDma<T>, D2: RxDma<T>>( peri: Peri<'d, T>, tx_dma: Peri<'d, D1>, rx_dma: Peri<'d, D2>, irq: impl Binding<D1::Interrupt, InterruptHandler<D1>> + Binding<D2::Interrupt, InterruptHandler<D2>> + 'd, ) -> Self

Create a new asynchronous SubghzSpi driver using DMA.

pub async fn write(&mut self, words: &[u8]) -> Result<(), Error>

Send a write command or buffer asynchronously over SUBGHZSPI.

pub async fn read(&mut self, words: &mut [u8]) -> Result<(), Error>

Read data asynchronously from SUBGHZSPI.

pub async fn transfer( &mut self, read: &mut [u8], write: &[u8], ) -> Result<(), Error>

Perform a full-duplex asynchronous transfer over SUBGHZSPI.

pub async fn transfer_in_place(&mut self, words: &mut [u8]) -> Result<(), Error>

Perform an in-place asynchronous transfer over SUBGHZSPI.

impl<'d> SubghzSpi<'d, Blocking>

pub fn new_blocking<T: Instance>(peri: Peri<'d, T>) -> Self

Create a new blocking SubghzSpi driver without DMA.

pub fn blocking_write(&mut self, words: &[u8]) -> Result<(), Error>

Send a write command or buffer blockingly over SUBGHZSPI.

pub fn blocking_read(&mut self, words: &mut [u8]) -> Result<(), Error>

Read data blockingly from SUBGHZSPI.

pub fn blocking_transfer( &mut self, read: &mut [u8], write: &[u8], ) -> Result<(), Error>

Perform a full-duplex blocking transfer over SUBGHZSPI.

pub fn blocking_transfer_in_place( &mut self, words: &mut [u8], ) -> Result<(), Error>

Perform an in-place blocking transfer over SUBGHZSPI.
