F24: Tilt Maze
Contents
Project Title
Tilt Maze
Abstract
Tilt Maze is a motion-controlled puzzle game that challenges players to navigate a luminous ball through procedurally generated mazes using device tilting mechanics. Players must reach the exit within time constraints while maneuvering around obstacles and collecting power-ups that provide temporary advantages. The game combines physical device control with strategic gameplay elements, offering high replayability through its randomized level design and emphasizing skills in balance, spatial reasoning, and quick decision-making.
Objectives & Introduction
The Tilt Maze Game combines hardware and software to create an interactive puzzle experience. It uses an ADXL345 accelerometer for tilt-based movement control, navigating a character through a maze displayed on a 64x64 LED matrix. FreeRTOS manages concurrent tasks like accelerometer input, display updates, and game logic, ensuring smooth and responsive gameplay. Game states, collision detection, and immersive audio feedback via an MP3 decoder enhance the experience. Semaphores and mutexes ensure thread-safe resource management, while debug outputs provide insights during development. This project demonstrates advanced integration of peripherals and real-time systems in a cohesive gaming application.

Design & Implementation
The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.
Hardware Design
Discuss your hardware design here. Show detailed schematics, and the interface here.
Hardware Interface
Hardware Interface
- **LED Matrix Display**: 13 GPIO channels on SJ2 microcontroller
- **Accelerometer (ADXL345)**: I2C communication on SJ2 microcontroller (SCL, SDA)
- **MP3 Decoder**: SPI communication using MOSI, CS, SCK on SJ2 microcontroller
- **Speaker**: AUX cord for audio output
- **Power Supply**: 5V/4A adapter for powering the LED matrix and SJ2 microcontroller
Software Design
- LED Matrix:
* 1. Initialized LED matrix connected pins to board IOs. * 2. Designed matrix driver for screen display by rendering maze patterns and player movements.
- Accelerometer:
* 1. Initialized I2C communication for ADXL345 accelerometer. * 2. Configured accelerometer in measurement mode and set sensitivity to ±2g. * 3. Processed tilt data to calculate real-time player movement commands.
- Mp3 Player:
* 1. Initialized using UART2. * 2. Set the device to the selected SD card and configured volume level. * 3. Played background music and sound effects based on game state.
Implementation
This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.
Testing & Technical Challenges
Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.
Include sub-sections that list out a problem and solution, such as:
<Bug/issue name>
Discuss the issue and resolution.
Conclusion
