F21: Juvenile Jumpers

Abstract

Doodle Jump is an endless platform game in which there are enemies and obstacles on various platforms. It is a single-player game. The doodle is a four-legged creature and has a trunk that he uses to shoot at enemies. The objective of the game is to go as high as you can without falling while avoiding/killing monsters and random obstacles. After each level, the difficulty of the game increases with more enemies and obstacles.

High level layout of Doodle Jump

Objectives & Introduction

The idea is to build the doodle jump game on a 64x64 RGB LED Screen. The game is played using a joystick. The doodle keeps on jumping and its direction can be controlled using left and right control of the joystick, which can also be used in forward and backward direction as gun to shoot the monsters. MP3 decoder is used for different sound effects in the background of game.

Design & Implementation

Juvenile Jumpers game is designed using SJ-Two board and RGB LED Matrix to see the visuals. The game is controlled by using a two-axis joystick and to play the music we have used an MP3 decoder.

Hardware Design

All the essential hardware is retained using a printed circuit board. For this game, we have designed a two-layer PCB. The schematic and board layout for the PCB is designed using Autodesk's Eagle software and fabrication vendor is JLPCB.

Dual Axis Joystick

This project uses the joystick to control the movements of the jumper and a switch on the joystick is used to start the game. The joystick provides the analog output, therefore the joystick is connected to ADC pins of the SJTwo board.

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

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

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?
