compatible way. Read more

impl<'a> SpiMaster<'a> for Iom<'a>
§type ChipSelect = &'a GpioPin<'a>
type ChipSelect = &'a GpioPin<'a>
Chip select is an associated type because different SPI
buses may have different numbers of chip selects. This
allows peripheral implementations to define their own type.
source§fn init(&self) -> Result<(), ErrorCode>
fn init(&self) -> Result<(), ErrorCode>
Initialize this SPI interface. Call this once before
invoking any other operations. Return values are: Read more
source§fn set_client(&self, client: &'a dyn SpiMasterClient)
fn set_client(&self, client: &'a dyn SpiMasterClient)
Change the callback handler for
read_write_bytes
calls.source§fn is_busy(&self) -> bool
fn is_busy(&self) -> bool
Return whether the SPI peripheral is busy with
read_write_bytes

Perform an asynchronous read/write operation, whose
completion is signaled by invoking SpiMasterClient on
the client. Write-only operations may pass
None
for
read_buffer
, while read-write operations pass Some
for read_buffer
. Read moresource§fn write_byte(&self, val: u8) -> Result<(), ErrorCode>
fn write_byte(&self, val: u8) -> Result<(), ErrorCode>
Synchronously write a single byte on the bus. Not for general
use because it is blocking: intended for debugging.
Return values: Read more
source§fn read_byte(&self) -> Result<u8, ErrorCode>
fn read_byte(&self) -> Result<u8, ErrorCode>
Synchronously write a 0 and read a single byte from the bus.
Not for general use because it is blocking: intended for debugging.
Return values: Read more
source§fn read_write_byte(&self, val: u8) -> Result<u8, ErrorCode>
fn read_write_byte(&self, val: u8) -> Result<u8, ErrorCode>
Synchronously write and read a single byte.

Return values: Read more
source§fn specify_chip_select(&self, cs: Self::ChipSelect) -> Result<(), ErrorCode>
fn specify_chip_select(&self, cs: Self::ChipSelect) -> Result<(), ErrorCode>
Specify which chip select to use. Configuration settings
(rate, polarity, phase) are chip-select specific and are
stored for that chip select.
source§fn set_rate(&self, rate: u32) -> Result<u32, ErrorCode>
fn set_rate(&self, rate: u32) -> Result<u32, ErrorCode>
Set the clock/data rate for the current chip select. Return values: Read more
source§fn set_polarity(&self, polarity: ClockPolarity) -> Result<(), ErrorCode>
fn set_polarity(&self, polarity: ClockPolarity) -> Result<(), ErrorCode>
Set the bus polarity (whether idle is high or low) for the
current chip select. Return values: Read more
source§fn get_polarity(&self) -> ClockPolarity
fn get_polarity(&self) -> ClockPolarity
Return the current bus polarity.
source§fn set_phase(&self, phase: ClockPhase) -> Result<(), ErrorCode>
fn set_phase(&self, phase: ClockPhase) -> Result<(), ErrorCode>
Set the bus phase for the current chip select (whether data is
sent/received on leading or trailing edges). Read more
source§fn get_phase(&self) -> ClockPhase
fn get_phase(&self) -> ClockPhase
Get the current bus phase for the current chip select.
source§fn hold_low(&self)
fn hold_low(&self)
Hold the chip select line low after a read_write_bytes completes.
This allows a client to make one long SPI read/write with
multiple calls to
read_write_bytes
.source§fn release_low(&self)
fn release_low(&self)
Raise the chip select line after a read_write_bytes completes.
This will complete the SPI operation.
