Struct SpiDevice

pub struct SpiDevice<Device: MpsseCmdExecutor> { /* private fields */ }

FTDI SPI device, a SPI bus with chip select pin.

This is created by calling FtHal::spi_device.

This is specific to embedded-hal version 1.

Implementations

impl<Device, E> SpiDevice<Device>

where Device: MpsseCmdExecutor<Error = E>, E: Error, Error<E>: From<E>,

pub fn set_clock_polarity<P: Into<Polarity>>(&mut self, cpol: P)

Set the SPI clock polarity.

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

Example

use eh1::spi::Polarity;
use ftdi_embedded_hal as hal;

let device = libftd2xx::Ft2232h::with_description("Dual RS232-HS A")?;
let hal = hal::FtHal::init_freq(device, 3_000_000)?;
let mut spi = hal.spi_device(3)?;
spi.set_clock_polarity(Polarity::IdleLow);
