Crate rpi_led_matrix

Rust bindings for the C++ library rpi-rgb-led-matrix.

Example Usage

use rpi_led_matrix::{LedMatrix, LedColor};
let matrix = LedMatrix::new(None, None).unwrap();
let mut canvas = matrix.offscreen_canvas();
for red in (0..255).step_by(16) {
    for green in (0..255).step_by(16) {
        for blue in (0..255).step_by(16) {
            canvas.fill(&LedColor { red, green, blue });
            canvas = matrix.swap(canvas);
        }
    }
}
