Include this [library](https://crates.io/crates/tca9539) as a dependency in your `Cargo.toml`:

```rust

[dependencies]

tca9539 = "0.1"

```

Use [embedded-hal](https://github.com/rust-embedded/embedded-hal) implementation to get I2C handle and then create chip handle:

```rust

use tca9539::*;

let pin = Pin::P13;

let mut u = Tca9539::default(i2c).unwrap();

u.set_direction(pin, Direction::Output).unwrap();

u.set_level(pin, Level::High).unwrap();

assert!(u.gpio(pin).unwrap());

```
