Struct SPI 

pub struct SPI<Miso, Mosi, Sck, Timer>
where
    Miso: InputPin,
    Mosi: OutputPin,
    Sck: OutputPin,
    Timer: CountDown + Periodic,
{ /* private fields */ }

A Full-Duplex SPI implementation, takes 3 pins, and a timer running at 2x the desired SPI frequency.

Implementations

impl<Miso, Mosi, Sck, Timer, E> SPI<Miso, Mosi, Sck, Timer>

where Miso: InputPin<Error = E>, Mosi: OutputPin<Error = E>, Sck: OutputPin<Error = E>, Timer: CountDown + Periodic,

pub fn new(mode: Mode, miso: Miso, mosi: Mosi, sck: Sck, timer: Timer) -> Self

Create instance

pub fn set_bit_order(&mut self, order: BitOrder)

Set transmission bit order

pub fn access_timer<F>(&mut self, f: F)

where F: FnOnce(Timer) -> Timer,

Allows for an access to the timer type. This can be used to change the speed.

In closure you get ownership of the timer so you can destruct it and build it up again if necessary.

Example

spi.access_timer(|mut timer| {
   timer.set_freq(4.mhz());
   timer
});

Trait Implementations

where Miso: InputPin<Error = E>, Mosi: OutputPin<Error = E>, Sck: OutputPin<Error = E>, Timer: CountDown + Periodic,

type Error = Error<E>

An enumeration of SPI errors

fn read(&mut self) -> Result<u8, Self::Error>

Reads the word stored in the shift register

fn send(&mut self, byte: u8) -> Result<(), Self::Error>

Sends a word to the slave
