Pixel Clock is a minimalist digital clock UI built using LVGL v9 on the ESP32-P4.
It displays pixel-style digits over a grid layout and includes a hidden snake animation mode to bring life to your embedded screen — all optimized for real-time performance and ease of integration.

Designed for LVGL-ready environments. Just configure your display and grid, and you're ready to run.

• Pixel-style digits using a 3×5 font layout on a tile grid
• Blinking colon that toggles every second
• Optimized redraw — updates only the digits that change
• Tap interaction — trigger random colorful falling tiles
• Snake game mode:
  • Triggers randomly during idle
  • Green snake moves toward red tile
  • Snake disappears on contact, restoring clock UI

• ESP32-P4 (ESP-IDF framework)
• LVGL v9
• Modular C code
• Simple grid logic (19×9 by default)
