libftd2xx-ffi

Rust FFI bindings to the FTDI D2XX drivers.

This crate is just the C bindings. There is a separate crate, libftd2xx, which provides safe wrappers around the unsafe C bindings.

Usage

Simply add this crate as a dependency in your Cargo.toml. The static library is distributed in this crate with permission from FTDI. The default feature set will use dynamic linking.

[dependencies]
libftd2xx-ffi = "~0.8.6"

Bindgen

The default feature set will use pre-generated bindings. This is only available for Windows x86_64 and Linux x86_64 platforms.

The bindings can also be generated during compilation using the bindgen feature flag.

[dependencies]
libftd2xx-ffi = { version = "~0.8.6", features = ["bindgen"] }

Bindgen has additional dependencies that must be installed in order to compile successfully, see the bindgen requirements page for more details.

Static Linking

Static linking the FTD2XX library into this crate can be done by using the static feature flag.

[dependencies]
libftd2xx-ffi = { version = "~0.8.6", features = ["static"] }

Static linking may be preferred, however there may be license incompatibilities (static linking with GPL code). If in doubt, check the FTDI driver license terms.
