Voted "Best Game" in ECE319K Class Competition (Fall 2025)

Features

• Multiplayer: UART-based protocol handling data packets for position syncing and item events (Banana/Bomb).
• Physics Engine: Custom collision detection (AABB), velocity and breaking mechanics, and bounce mechanics.
• Hardware Drivers: Direct register-level drivers for:
  • UART: Interrupt-driven networking.
  • SPI: display communication.
  • ADC: Joystick input processing.
  • DAC/Timer: Sound generation and game loop timing (30Hz).

Hardware Requirements

• Microcontroller: TI MSPM0G3507 LaunchPad.
• Display: ST7735 128x160 TFT LCD.
• Input: Analog Joystick (2-axis) + Buttons.
• Audio: DAC made with resistors + amplifier.

Build & Run

1. Clone the repo:

   git clone https://github.com/bshihab/Embedded-Multiplayer-Racer.git

2. Import the project folder into Code Composer Studio.
3. Build and Flash to the LaunchPad.
4. Multiplayer: Connect two boards via UART (Tx to Rx, Rx to Tx, GND to GND).

Project Structure

• /images: Raw sprite data arrays converted from BMPs.
• /sounds: Audio data arrays for game sound effects.
• Lab9Main.c: Main game loop and state machine.
• Graphics.c/h: LCD rendering logic.
• GameObjects.c/h: sprite management and collision logic.
