Struct ftd2xx_embedded_hal::Spi

pub struct Spi<'a, Device: FtdiCommon> { /* fields omitted */ }

FTDI SPI interface.

This is created by calling FtHal::spi.

Implementations

impl<'a, Device: FtdiCommon> Spi<'a, Device>

pub fn set_clock_polarity(&mut self, cpol: Polarity)

Set the SPI clock polarity.

FTD2XX devices only supports SPI mode 0 and 2, clock phase is fixed.

Example

use embedded_hal::spi::Polarity;
use ftd2xx_embedded_hal as hal;

let ftdi = hal::Ft232hHal::new()?.init_default()?;
let mut spi = ftdi.spi()?;
spi.set_clock_polarity(Polarity::IdleLow);
