Tetris - Purdue Proton

This project implements a multiplayer Tetris variant on the Purdue Proton development board, which uses the same 2350B microcontroller as the Raspberry Pi Pico 2.

Overview

Battle Tetris runs on a 64×64 RGB LED matrix and supports head-to-head multiplayer using UART communication between two Proton boards.
Gameplay uses an NES controller for input, includes custom audio playback over PWM, and features a full UI rendered with a custom bitmap font.

Core Features

• LED Matrix Graphics
  Rendering to a 64×64 Adafruit matrix using GPIO and DMA-driven framebuffer updates.

• NES Controller Input
  GPIO-based polling and detection of an original NES controller.

• Multiplayer Support
  Board-to-board communication over UART via a USB-A cable for real-time competitive gameplay.

• Audio System PWM-based playback of music and sound effects through a filtered line-level output, with double-buffered DMA streaming.

Team Roles

• Andrei – game logic and coordination
• Raahil – graphics engine, enclosure design
• Amy – audio system and UI
• Davis – multiplayer communication and input hardware
