Project Midway Report

Overview

DDRUM is a four-pad rhythm game in the spirit of DDR and Guitar Hero. Notes descend in four lanes on a display while a song plays. The player strikes one of four drum pads on the beat, and the system scores accuracy as Perfect, Good, or Miss with real-time visual feedback and a running score/combo.

Specifications

• Audio Playback: .wav file playback via MCU DAC
• Input Detection: Four piezo sensors captured by the FPGA with clear inputs
• Visual Features: At least Four lanes, falling notes, combo counter, and live updates based on hits
• Memory Reading: Reads music files, premade beatmaps, and reads/writes a persistent high-score leaderboard from an SD card using FatFs.
• Synchronization: Smooth visuals, accurate scoring, synchronized audio, and a full playable song with consistent performance.
• Reach Goal: Random Mode: 3 Game modes that vary on difficulty, selecting all bass notes randomly
• Reach Goal: Audio Analysis: Successful beat-detection using MIDI File Read
