driver-64x64-pixel-matrix

HUB75 RGB LED matrix driver for ESP32. Designed for 64×64 panels in 1/32 scan, but configurable for other sizes via generics const.

Features

• Bit-bang HUB75 protocol over GPIO (no RMT/I2S required)
• 1-bit-per-color display (8 colors)
• Configurable panel size via generics (PixelMap<W, H>)
• no_std compatible
• FPS counter in demo binaries

Hardware

Default pinout

Pins are fully configurable via Hub75Pins::new().

Usage

use driver_64x64_pixel_matrix::{display_frame, Hub75Pins, PixelMap, Rgb565};

let mut pins = Hub75Pins::new(/* 14 GPIO outputs */);
let mut fb = PixelMap::<64, 64>::new();

fb.fill(Rgb565::red());

loop {
    display_frame(&mut pins, &fb);
}

Examples

# Solid colors cycling
cargo run --example solid_colors

# Checkerboard pattern
cargo run --example checkerboard

# Vertical color bars
cargo run --example color_bars
