Introduction

Jubeat is a music game uses an arrangement of a 3x4 grid for the game play. An animation pops up on each grid according to the beat of the song. The player has to use his fingers to tap on the screen and catch the animation in time. Different scores will be given depending on when the player catch the animation. Tapes can be judged as PERFECT, GOOD, OK, and MISS.

Objectives & Introduction

This system:

1. Recognizes finger touch as the input to record the score.

2. Supports real time capacitive touch detection on a LED matrix display.

3. Update corresponding score on the LED display.

4. Outputs the audio via a mp3 module and the soundtracks are stored in an SD card.

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.

For detailed schematic, [click 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.

Software Design

Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

Implementation

The 64x64 matrix display is divided into 4 rows, the top row (16x64) is used as a scoreboard, and the remaining rows are divided into 12 square regions, each 16x16 that connects to the ITO buttons that connects to the capacitive sensor for the game input.

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

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
