In this project, we've created a version of the classic Space Invaders game. Instead of using a traditional joystick, the player controls the spaceship's movement using a linear potentiometer that responds to touch. The spaceship shoots to destroy enemies, and the entire game map scrolls in the opposite direction of the spaceship's movement. As the game progresses, the speed of the map's flow and the number of enemies increase, adding more challenge. The spaceship's health decreases when it collides with enemies or their bullets, and the game ends when the health reaches zero.

Introduction

In this project, we've created a version of the classic Space Invaders game. Instead of using a traditional joystick, the player controls the spaceship's movement using a linear potentiometer that responds to touch. The spaceship shoots to destroy enemies, and the entire game map scrolls in the opposite direction of the spaceship's movement. As the game progresses, the speed of the map's flow and the number of enemies increase, adding more challenge. The spaceship's health decreases when it collides with enemies or their bullets, and the game ends when the health reaches zero.

Design & Implementation

The 64x64 RGB LED Matrix connects to the SJ-Two microcontroller via GPIO pins, with additional connections for power and ground. The YX5300 MP3 decoder interfaces with the same microcontroller using UART TX and RX pins for serial communication. The decoder also has connections to an SD card for audio files and outputs audio to a connected speaker or amplifier, completing the setup for synchronized visuals and sound.

Hardware Design

Discuss your hardware design here. Show detailed schematics, and the interface here.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Supported Specifications

  • File Formats: MP3, WAV
  • Sampling Frequencies: 8 kHz, 11.025 kHz, 12 kHz, 16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, 48 kHz
  • SD cards (≤2GB) / SDHC cards (≤32GB)
  • File System: FAT16, FAT32
  • UART Baud Rate: 9600 bps
  • Volume Levels: 30 adjustable levels in hex
  • Power Supply: 3.2–5.2 VDC (3.3V)
  • Naming Songs:Name audio files as 001sng.mp3, 002sng.mp3, etc., and place them in folders like 01, 02 etc

Software Design

We developed a driver for the MP3 player module that sets up UART communication and connects the RX and TX pins properly. The driver makes it easy to send commands to the MP3 player, such as adjusting the volume, playing specific songs by their number or folder, skipping tracks, and setting playback modes like repeatt. For more details, check out the user manual: [3]

Implementation

  • Initialize MP3 decorder: Get the MP3 player ready by selecting the SD card that has your songs.
  • Cycle play mode: Set a song to play on repeat.
  • Pause a song: Temporarily stop playback.
  • Resume playback: Continue playing the song from where it was paused.
  • Play by index: Start playback of a specific song using its number.
  • Set volume: Adjust the playback volume to a desired level.
  • Next song: Skip to the next track in the playlist.
  • Previous song: Go back to the previous track in the playlist.

Code Structure

  • Initialization: Call sound_manager__init() to set up the sound manager, including initializing the MP3 decoder, creating FreeRTOS tasks for each sound effect, and configuring semaphores for synchronization.
  • Pin Selection: Configure the UART pins in mp3_dec.c using gpio__construct_with_function() to match your hardware setup.
  • Sound Effects: Trigger sound effects using the provided functions in the sound manager:

sound_manager__play_laser();
sound_manager__play_explosion();
sound_manager__play_won_game();
mp3_decoder__play_song_at_index(0x01);
