F20: Flappy
Contents
FLAPPY
Abstract
FLAPPY is one of the most anticipated gaming machines of the year 2020. Adopted the timeless design of the Gameboy Advance, it can play one and only one game(albeit the best game of all time in our opinion): FLAPPY BIRD. The player is advised to move the main character wisely (up and down) to NOT hit the beautiful green pipe. With simple gameplay and catchy music, it guarantees thousands of seconds of interesting game for the entire family.
Objectives & Introduction
The main objective of our project was to re-create the iconic Flappy Bird mobile game into a physical gaming device. Our team tried to simplify the device in accordance with the original game spirit: its simplicity. Using the SJ2 board, our team started by researching for suitable components and interfaced them together to replicate Flappy Bird
Objectives:
- Smooth button usage and it must handle the push differently based on the scenes
- Write a simple driver to communicate with the LED
- Write a separate driver for game graphic
- Design a state machine to handle different game tasks such as the start screen, gameplay, and ending screen
- Implement the game logic for movement of the bird, collision detection, randomized obstacle generation, and a score keeping system

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
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
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>
<1. Unit Testing vs Combined Design>
We faced some unexpected issues when putting our project together. When testing each component individually they would preform to our expectations, but issues would arise when multiple components were used in tandem or on the PCB vs. direct GPIO connections.
<2. Music/Sound Effect Playback>
One of the issues we experienced was our speakers only outputting noise during final project testing. This issue did not show up when testing parts individually using the SJ2 as a 3.3V power source. The issue was however determined to be the SJ2. Although it correctly flashed code and ran the LED matrix or DAC+AMP individually without issue, when combined the DAC was unable to output music. Using a different groupmate's SJ2 solved the issue completely.
<3. RGB LED Matrix Some Brighter LED Rows>
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?
