Control RGB LED displays from Rust
This repository contains rust bindings for the C++ library rpi-rgb-led-matrix, which enables controlling Hub75 based displays. In order to take advantage of the newer APIs, the minimum supported commit of the library is 55fa32f (Sept. 7th, 2020), which exposes all parameters that affect how the matrix runs.
Usage
The examples have more detailed usage, but here is basic usage to get things rendering on your display.
use rpi_led_matrix::{LedMatrix, LedColor};
let matrix = LedMatrix::new(None, None).unwrap();
let mut canvas = matrix.offscreen_canvas();
for red in 0..255 {
for green in 0..255 {
for blue in 0..255 {
canvas.fill(&LedColor { red, green, blue });
canvas = matrix.swap(canvas);
}
}
}Note that if you have wirings other than the libraries "default", you will need to construct arguments to the library to specify the layout. See LedMatrixOptions for more information.
