Implementations

impl<REMAP, PINS> Spi<SPI1, REMAP, PINS, u8, Master>

pub fn spi1( spi: SPI1, pins: PINS, mapr: &mut MAPR, mode: Mode, freq: Hertz, clocks: Clocks, ) -> Self

where REMAP: Remap<Periph = SPI1>, PINS: Pins<REMAP>,

Constructs an SPI instance using SPI1 in 8bit dataframe mode.

The pin parameter tuple (sck, miso, mosi) should be (PA5, PA6, PA7) or (PB3, PB4, PB5) configured as (Alternate<...>, Input<...>, Alternate<...>).

You can also use NoSck, NoMiso or NoMosi if you don’t want to use the pins
