Module stm32f1xx_hal::spi

Serial Peripheral Interface

To construct the SPI instances, use the Spi::spiX functions.

The pin parameter is a tuple containing (sck, miso, mosi) which should be configured as (Alternate<PushPull>, Input<Floating>, Alternate<PushPull>).

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

• SPI1 can use (PA5, PA6, PA7) or (PB3, PB4, PB5).
• SPI2 can use (PB13, PB14, PB15)
• SPI3 can use (PB3, PB4, PB5) or (PC10, PC11, PC12)

Initialisation example

  // Acquire the GPIOB peripheral
  let mut gpiob = dp.GPIOB.split(&mut rcc.apb2);

  let pins = (
      gpiob.pb13.into_alternate_push_pull(&mut gpiob.crh),
      gpiob.pb14.into_floating_input(&mut gpiob.crh),
      gpiob.pb15.into_alternate_push_pull(&mut gpiob.crh),
  );

  let spi_mode = Mode {
      polarity: Polarity::IdleLow,
      phase: Phase::CaptureOnFirstTransition,
  };
  let spi = Spi::spi2(dp.SPI2, pins, spi_mode, 100.khz(), clocks, &mut rcc.apb1);
