Blinkt

Blinkt is a Rust library that provides an interface for the Pimoroni Blinkt!, and any similar APA102 or SK9822 strips or boards, on a Raspberry Pi.

Blinkt accesses the BCM283x GPIO peripheral either through /dev/gpiomem (preferred) or /dev/mem. Both the original APA102 and the SK9822 clone are supported. The APA102 RGB LED/driver ICs are referred to as pixels throughout the code and documentation.

Documentation

Documentation for the latest release can be found at docs.golemparts.com/blinkt. Documentation for earlier releases is stored at docs.rs/blinkt.

Usage

Add a dependency for blinkt to your Cargo.toml.

toml [dependencies] blinkt = "0.3"

Link and import blinkt from your crate root.

rust extern crate blinkt;

Call Blinkt::new() to create a new Blinkt with the default settings. In production code, you'll want to parse the result rather than unwrap it.

```rust use blinkt::Blinkt;

let mut blinkt = Blinkt::new().unwrap(); ```

Example

```rust extern crate blinkt;

use std::{thread, mem}; use std::time::Duration;

use blinkt::Blinkt;

fn main() { let mut blinkt = Blinkt::new().unwrap(); let (red, green, blue) = (&mut 255, &mut 0, &mut 0);

loop {
    blinkt.set_all_pixels(*red, *green, *blue);
    blinkt.show();

    thread::sleep(Duration::from_millis(250));

    mem::swap(red, green);
    mem::swap(red, blue);
}

} ```
