Implementations

impl<PINS> Spi<SPI1, PINS>

where PINS: Pins<SPI1>,

impl<PINS> Spi<SPI2, PINS>

pub fn spi2( spi: SPI2, pins: PINS, mode: Mode, freq: Hertz, clocks: Clocks, ) -> Self

where PINS: Pins<SPI2>,

impl<PINS> Spi<SPI3, PINS>

pub fn spi3( spi: SPI3, pins: PINS, mode: Mode, freq: Hertz, clocks: Clocks, ) -> Self

where PINS: Pins<SPI3>,

impl<PINS> Spi<SPI4, PINS>

pub fn spi4( spi: SPI4, pins: PINS, mode: Mode, freq: Hertz, clocks: Clocks, ) -> Self

where PINS: Pins<SPI4>,

impl<PINS> Spi<SPI5, PINS>

pub fn spi5( spi: SPI5, pins: PINS, mode: Mode, freq: Hertz, clocks: Clocks, ) -> Self

where PINS: Pins<SPI5>,

impl<PINS> Spi<SPI6, PINS>

pub fn spi6( spi: SPI6, pins: PINS, mode: Mode, freq: Hertz, clocks: Clocks, ) -> Self

where PINS: Pins<SPI6>,

impl<SPI, PINS> Spi<SPI, PINS>

where SPI: Deref<Target = RegisterBlock>,

pub fn init(self, mode: Mode, freq: Hertz, clock: Hertz) -> Self

pub fn listen(&mut self, event: Event)

Enable interrupts for the given event:

• Received data ready to be read (RXNE)
• Transmit data register empty (TXE)
• Transfer error

pub fn unlisten(&mut self, event: Event)

Disable interrupts for the given event:

• Received data ready to be read (RXNE)
• Transmit data register empty (TXE)
• Transfer error

pub fn is_txe(&self) -> bool

Return true if the TXE flag is set, i.e. new data to transmit can be written to the SPI.

pub fn is_rxne(&self) -> bool

Return true if the RXNE flag is set, i.e. new data has been received and can be read from the SPI.

pub fn is_modf(&self) -> bool

Return true if the MODF flag is set, i.e. the SPI has experienced a Master Mode Fault. (see chapter 28.3.10 of the STM32F4 Reference Manual)

pub fn is_ovr(&self) -> bool

Return true if the OVR flag is set, i.e. new data has been received while the receive data register was already filled.

pub fn free(self) -> (SPI, PINS)
