Struct ftd2xx_embedded_hal::Ft232hHal

pub struct Ft232hHal<INITIALIZED> { /* fields omitted */ }

FT232H device.

Implementations

impl Ft232hHal<Uninitialized>

pub fn new() -> Result<Ft232hHal<Uninitialized>, DeviceTypeError>

Create a new FT232H structure.

Example

use ftd2xx_embedded_hal as hal;

let ftdi = hal::Ft232hHal::new()?.init_default()?;

pub fn with_serial_number(
    sn: &str
) -> Result<Ft232hHal<Uninitialized>, DeviceTypeError>

Create a new FT232H structure from a serial number.

Example

use ftd2xx_embedded_hal as hal;

let ftdi = hal::Ft232hHal::with_serial_number("FT6ASGXH")?.init_default()?;

pub fn with_description(
    description: &str
) -> Result<Ft232hHal<Uninitialized>, DeviceTypeError>

Open a Ft4232h device by its device description.

Example

use libftd2xx::Ft4232h;

Ft4232h::with_description("FT4232H-56Q MiniModule A")?;

pub fn init_default(self) -> Result<Ft232hHal<Initialized>, TimeoutError>

Initialize the FTDI MPSSE with sane defaults.

Default values:

• Reset the FTDI device.
• 4k USB transfer size.
• 1s USB read timeout.
• 1s USB write timeout.
• 16ms latency timer.
• 100kHz clock frequency.

Example

use ftd2xx_embedded_hal as hal;
use hal::{Ft232hHal, Initialized, Uninitialized};

let ftdi: Ft232hHal<Uninitialized> = hal::Ft232hHal::new()?;
let ftdi: Ft232hHal<Initialized> = ftdi.init_default()?;

pub fn init(
    self,
    mpsse_settings: &MpsseSettings
) -> Result<Ft232hHal<Initialized>, TimeoutError>

Initialize the FTDI MPSSE with custom values.

Note: The mask field of MpsseSettings is ignored for this function.

Panics

Panics if the clock_frequency field of MpsseSettings is None.

Example

use ftd2xx_embedded_hal as hal;
use hal::libftd2xx::MpsseSettings;
use hal::{Ft232hHal, Initialized, Uninitialized};

let ftdi: Ft232hHal<Uninitialized> = hal::Ft232hHal::new()?;
let ftdi: Ft232hHal<Initialized> = ftdi.init(&MpsseSettings {
    clock_frequency: Some(500_000),
    ..MpsseSettings::default()
})?;

impl Ft232hHal<Initialized>

pub fn spi(&self) -> Result<Spi<'_>, TimeoutError>

Aquire the SPI peripheral for the FT232H.

Pin assignments:

• AD0 => SCK
• AD1 => MOSI
• AD2 => MISO

Panics

Panics if pin 0, 1, or 2 are already in use.

Example

use ftd2xx_embedded_hal as hal;

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

pub fn i2c(&self) -> Result<I2c<'_>, TimeoutError>

Aquire the I2C peripheral for the FT232H.

Pin assignments:

• AD0 => SCL
• AD1 => SDA
• AD2 => SDA

Yes, AD1 and AD2 are both SDA. These pins must be shorted together for I2C operation.

Panics

Panics if pin 0, 1, or 2 are already in use.

Example

use ftd2xx_embedded_hal as hal;

let ftdi = hal::Ft232hHal::new()?.init_default()?;
let mut i2c = ftdi.i2c()?;

pub fn ad0(&self) -> OutputPin<'_>

Aquire the digital output pin 0 for the FT232H.

Panics

Panics if the pin is already in-use.

pub fn ad1(&self) -> OutputPin<'_>

Aquire the digital output pin 1 for the FT232H.

Panics

Panics if the pin is already in-use.

pub fn ad2(&self) -> OutputPin<'_>

Aquire the digital output pin 2 for the FT232H.

Panics

Panics if the pin is already in-use.

pub fn ad3(&self) -> OutputPin<'_>

Aquire the digital output pin 3 for the FT232H.

Panics

Panics if the pin is already in-use.

pub fn ad4(&self) -> OutputPin<'_>

Aquire the digital output pin 4 for the FT232H.

Panics

Panics if the pin is already in-use.

pub fn ad5(&self) -> OutputPin<'_>

Aquire the digital output pin 5 for the FT232H.

Panics

Panics if the pin is already in-use.

pub fn ad6(&self) -> OutputPin<'_>

Aquire the digital output pin 6 for the FT232H.

Panics

Panics if the pin is already in-use.

pub fn ad7(&self) -> OutputPin<'_>

Aquire the digital output pin 7 for the FT232H.

Panics

Panics if the pin is already in-use.
