Project Title
Survival Dodge
Abstract
Survival Dodge is a classic arcade-style game focused on quick reflexes and survival, reminiscent of retro gaming experiences. This project aims to recreate the intense and fast-paced gameplay using the SJ-2 board and an LED matrix display. In this game, players control a character (or an object) that must dodge incoming obstacles from multiple directions, with the speed and frequency of obstacles increasing over time. The objective is to survive as long as possible, setting high scores based on survival time. Players will use buttons or a joystick to maneuver, with core implementation focusing on responsive controls, real-time collision detection, and adaptive difficulty for sustained challenge.
Objectives & Introduction
"Survival Dodge" aims to create an engaging game where players maneuver a character to avoid obstacles and accumulate points, displayed on an LED matrix. As players progress, the game increases in difficulty by accelerating the obstacles, testing reflexes and enhancing engagement through simple button-based controls.

Design & Implementation
LED Matrix Display:
The 64 x 64 LED matrix comprises 4,096 pixels, each equipped with three channels for the colors red, green, and blue. The matrix uses a 5:32 decoder to address every two rows simultaneously, resulting in two distinct sections: the upper half includes rows 0 to 31, and the lower half consists of rows 32 to 64. To activate each LED, the corresponding RGB pins must be set to HIGH and fed into a 64-bit shift register that aligns with the matrix's 64 columns. The upper half of the display is managed by the RGB pins labeled R1, G1, and B1, while the lower half is controlled by R2, G2, and B2.
The figure and table below shows the pin-out of RGB LED matrix with description.

Momentary Press Buttons
We utilized Weideer 16mm Push buttons sourced from Amazon for user input. These buttons offered a tactile response and a specific degree of switch travel, with each button featuring two terminals. We wired one terminal of each button to three distinct GPIO pins on the SJ2 Board for input signal reception. The other terminal was connected to the 3.3V Vcc of the SJ2. To avoid any floating inputs when the buttons were not active, we activated pull-down resistors in the software for these switches.
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.

Conclusion
Developing "Survival Dodge" was a highly engaging and stimulating experience that kept us constantly intrigued. Tackling the various technical challenges, particularly in adjusting the game dynamics and LED matrix display, enhanced our practical problem-solving skills. Through this project, we applied key concepts from our game design and software engineering coursework, gaining deeper insights into real-time system management and user interface design. Collaborating on this project not only honed our teamwork and time management skills but also boosted our confidence in handling complex embedded systems and preparing for technical interviews.
