F20: Treasure Diver

Abstract

Treasure Diver is a single player game in which the player descends into watery depths on the hunt for treasure. The player must dodge obstacles and enemy creatures all while collecting treasure along the way. While descending the player is able to attack enemies at a range which in turn may give them power ups such as extra air, faster move speed, or temporary invincibility. When they reach the bottom they can collect the Motherlode. After that they have to ascend the cavern and make it out with all their treasure in one piece. Hitting an enemy or obstacle causes the player to lose air and a treasure chest and when their air hits zero it’s game over. At the end of a level the player is given a score based on treasure collected, remaining air, and the amount of enemies destroyed.

Parts List & Cost

Give a simple list of the cost of your project broken down by components. Do not write long stories here.

Design & Implementation

Insert diagram of all modules connected to each sj2 board (using pictures of actual modules)

PCB Design

Brief description. Insert PCB schematics and pictures of actual pcbs

CAD Enclosures Design

Brief description. Insert CAD design screenshots and pics of actual enclosures

RGB LED Matrix

Brief description of what this module does. Insert diagram of led matrix connected to sj2 (using pictures of actual modules)

Hardware Design

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

Use a flowchart(s)

Implementation

Short code snippets or pseudo-code with explanations

MP3 Decoder

The YX5300 MP3 Music Player Module is used in the project to play music at the menu, gameplay and at the Victory/Gameover screen. Although we use it to decode MP3 files, it can also decode MAV files. This board contains a slot for SD card mounting, which we command the module to read from. Insert diagram of MP3 decoder connected to sj2 (using pictures of actual modules)

Hardware Design

This module is easy to interface since it only uses UART pins (Rx and Tx), excluding the Vcc and Ground. This board was able to be powered with the 3.3V power from the SJ2 board. The MP3 decoder was connected to 2 SJ2 pins....(to be continued). Discuss your hardware design here. Show detailed schematics, and the interface here. In this section, you can describe how your hardware communicates, such as which BUSes used.

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:

CAD Enclosures Design

• Discuss issue and resolution 1.
• Discuss issue and resolution 2.
• Discuss issue and resolution n.

PCB Design

• Discuss issue and resolution 1.
• Discuss issue and resolution 2.
• Discuss issue and resolution n.

LED Matrix

• Discuss issue and resolution 1.
• Discuss issue and resolution 2.
• Discuss issue and resolution n.

MP3 Decoder

• The datasheet lacks some information and clarity on initializing the module and with some of the commands. When first using it, non of the commands appeared to work or have any effect. The issue was resolved after sending the command to select a device, which was not explicitly stated in the datasheet. Once this command is first sent, the MP3 decoder now begins accepting commands.
• Discuss issue and resolution 2.
• Discuss issue and resolution n.

Bluetooth Interface

• Discuss issue and resolution 1.
• Discuss issue and resolution 2.
• Discuss issue and resolution n.

Game Pad Controller

• Discuss issue and resolution 1.
• Discuss issue and resolution 2.
• Discuss issue and resolution n.

Advice for Future Students

CAD Enclosures Design

• Advice/tip #1
• Advice/tip #2
• Advice/tip #n

PCB Design

• Use EasyEDA to design your PCBs. It has an auto-routing feature so you don't have to perform any routing by hand which saves you so much time. It also automatically converts your schematic to components that you just "drag and drop" onto your PCB while the connections are automatically maintained.
• Order your PCBs from JLCPCB (integrated into EasyEDA). You'll get them in 1 week.
• In EasyEDA, may sure you check the connections for each footprint you're using. Sometimes the footprint's pinout won't exactly match your schematic.
