Implementations

impl<'d, DEVICE, DRIVER> SpiSoftCsDeviceDriver<'d, DEVICE, DRIVER>

where DEVICE: Borrow<SpiSharedDeviceDriver<'d, DRIVER>>, DRIVER: Borrow<SpiDriver<'d>> + 'd,

pub fn new( shared_device: DEVICE, cs: impl Peripheral<P = impl OutputPin> + 'd, cs_level: Level, ) -> Result<SpiSoftCsDeviceDriver<'d, DEVICE, DRIVER>, EspError>

pub fn cs_pre_delay_us( &mut self, delay_us: u32, ) -> &mut SpiSoftCsDeviceDriver<'d, DEVICE, DRIVER>

Add an aditional Amount of SPI bit-cycles the cs should be activated before the transmission (0-16). This only works on half-duplex transactions.

pub fn cs_post_delay_us( &mut self, delay_us: u32, ) -> &mut SpiSoftCsDeviceDriver<'d, DEVICE, DRIVER>

Add an aditional delay of x in uSeconds after transaction between last clk out and chip select

pub fn transaction( &mut self, operations: &mut [Operation<'_, u8>], ) -> Result<(), EspError>

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

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

pub fn transfer_in_place(&mut self, buf: &mut [u8]) -> Result<(), EspError>

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

fn read( &mut self, buf: &mut [u8], ) -> Result<(), <SpiSoftCsDeviceDriver<'d, DEVICE, DRIVER> as ErrorType>::Error>

Do a read within a transaction.

fn write( &mut self, buf: &[u8], ) -> Result<(), <SpiSoftCsDeviceDriver<'d, DEVICE, DRIVER> as ErrorType>::Error>

Do a write within a transaction.

fn transaction( &mut self, operations: &mut [Operation<'_, u8>], ) -> Result<(), <SpiSoftCsDeviceDriver<'d, DEVICE, DRIVER> as ErrorType>::Error>

fn transfer( &mut self, read: &mut [Word], write: &[Word], ) -> Result<(), Self::Error>

Do a transfer within a transaction.

fn transfer_in_place(&mut self, buf: &mut [Word]) -> Result<(), Self::Error>

Do an in-place transfer within a transaction.
