Implementations

impl Ft4232h

pub unsafe fn with_serial_number_unchecked( serial_number: &str, ) -> Result<Ft4232h, FtStatus>

Open a Ft4232h device and initialize the handle.

Safety

This is unchecked meaning a device type check will not be performed. Methods that require this specific device type may fail in unexpected ways if the wrong device is used.

Example

use libftd2xx::Ft4232h;

let mut ft = unsafe { Ft4232h::with_serial_number_unchecked("FT4PWSEOA")? };

pub fn with_serial_number( serial_number: &str, ) -> Result<Ft4232h, DeviceTypeError>

Open a Ft4232h device and initialize the handle.

Example

use libftd2xx::Ft4232h;

Ft4232h::with_serial_number("FT4PWSEOA")?;

pub fn with_description(description: &str) -> Result<Ft4232h, DeviceTypeError>

Open a Ft4232h device by its device description.

Example

use libftd2xx::Ft4232h;

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