A high-speed, vertical Pong clone designed specifically for the Waveshare ESP32-S3-Touch-LCD-4.3.

This project demonstrates how to handle 2D game physics, touch input mapping, and high-performance rendering using LVGL on the ESP32-S3, achieving a smooth ~30 FPS without screen tearing.

• Vertical Gameplay: Optimized for the 480x800 Portrait orientation.
• Smart Touch Control: "Drag Anywhere" input. You don't need to cover the paddle with your finger; dragging anywhere on the screen controls the player paddle.
• Simple AI: An automated opponent tracks the ball with adjustable difficulty settings.
• Smooth Physics: Dedicated timer-based physics loop running independently of the rendering loop.
• Neon Aesthetics: High-contrast visuals (Black BG, Neon Green Player, Neon Red AI).

• Board: Waveshare ESP32-S3-Touch-LCD-4.3 (480x800 RGB Interface).
• Power: USB-C.

This project relies on the Espressif Display Panel framework. Ensure you have the following installed in Arduino IDE:

Your sketch folder must contain these specific configuration files to match the Waveshare hardware:

• pong.ino: The main game logic.
• esp_panel_board_custom_conf.h: Defines the specific RGB timing and pinout for this board.
• lvgl_v8_port.h & .cpp: Handles the LVGL buffer flushing and task management.

To prevent screen flickering and ensure touch inputs align with the vertical screen, you must configure lvgl_v8_port.h exactly as follows:

// In lvgl_v8_port.h

// 1. Use Partial Refresh (Mode 0) for stable performance
#define LVGL_PORT_AVOID_TEARING_MODE      (0)

// 2. Rotate the Touch Input 90 degrees to match Portrait orientation
#define LVGL_PORT_ROTATION_DEGREE         (90)
