easyopc - Open Pixel Control in Rust

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

Usage

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();
    });
}

Stability

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

Configuration is drawn from environment variables with sensible defaults.

Examples

Random Pixels

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

cargo run --example random_pixels

RGB Rotate

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

cargo run --example rgb_rotate
