An ergonomics-first Open Pixel Control client for devices like Fadecandy and Total Control Lighting.

extern crate easyopc;

use easyopc::*;

fn main() {
    let mut opc = PixelControl::default();
    let mut pixels = vec![Pixel{r:0,g:0,b:0}; 512];
    draw_with_interval_ms(1000, ||{
        for i in 0..512 {
            pixels[i] = opc.random_color();
        }
        opc.emit(&pixels).unwrap();
    });
}

This library is currently pre-1.0, which means breaking changes will happen. Consider pinning to a specific version to not have your build break.

My intention for this library is to create a small set of examples and simplify the api as needed to make the examples easier, more succinctly expressive, and simpler. Once I have a diverse set of examples at a satisfactory local minimum of complexity, I'll stabilize the library. Please open an issue if you have an example that's overly difficult to implement.

Configuration is drawn from environment variables with sensible defaults.

Sets ever pixel in the canvas to a random RGB value every second.

cargo run --example random_pixels

Rotates through red, green, and blue every 10 seconds. This demonstrates crossfading well.
