Project Title

Goals of Glory

Abstract

Gesture-based gaming is getting tremendous adoption due to immersive gameplay and increased player engagement. Goals of Glory is a classic penalty shootout game where 2 players can play wirelessly, and the corresponding game visuals are displayed on the LED Matrix in real time. The logic for player movement is based on the output from a Gyroscope and an Accelerometer embedded on MPU 6050 whereas accelerometer on the SJone helps drive goalkeeper movements. Thus the motion of player leg movements to kick and hand movements of the goalkeeper to stop the ball is mapped and the corresponding game animations are displayed on 64x64 LED Matrix. The LED matrix is interfaced to the SJone board in such a way that the main SJone board controlling the LED Matrix receives commands wirelessly from hand and leg movements of each player via the Nordic wireless mesh network. Three display screens are developed for the game UI- Start screen, Game screen, and Result screen. Thus, by playing Goals of Glory, players can experience gesture-based gaming capabilities.

Objectives & Introduction

Introduction

The project is divided into 3 modules

1) LED Module: The 64x64 LED matrix is driven by a Master SJone board which is responsible to map game visuals.

2) Wireless Module: Responsible for communication medium between the goalkeeper, player, and main SJone board

3) Accelerometer Module: This module is responsible for getting the player and goalkeeper movement that will later be mapped to drive game visuals

Game Stats:

2-Player Penalty shootout Game
3-sec timer for each player to shoot
Press switch on the main SJOne board to start
Move the Goalkeeper SJone board left-right to have a corresponding movement of LED Matrix
Control the ball movement via player SJone board to give direction i.e. left, right or straight
Highest player to score wins and is displayed on the result screen

Objectives

Our project involved a focused and rigorous approach to testing each module functionality and make necessary changes thereafter.

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.

Nordic S

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>

-'''Nordic Wireless'''<br>
-The project uses nRF24L01+ single chip 2.4GHZ transceiver rooted on SJone board to establish wireless communication between input and output modules. It uses embedded baseband protocol engine (Enhanced ShockBurst™), suitable for ultra low power wireless applications. The nRF24L01+ is designed for operation in the world wide ISM frequency band at 2.400 - 2.4835GHz. It is configured and operated through Serial Peripheral Interface (SPI0) of LPC1758 microcontroller. The embedded baseband protocol engine (Enhanced ShockBurst™) is based on packet communication and supports various modes from manual operation to advanced autonomous protocol operation. Internal FIFOs ensure a smooth data flow between the radio front end and the system’s MCU. Enhanced Shock-Burst™ reduces system cost by handling all the high speed link layer operations. The radio front end uses GFSK modulation. It consists of 126 different RF channels, which gives a possibility to have a network of 125 independently working modems in one place. It has a power consumption of about 12mA during transmission which is even lower than a single LED. Its operating voltage is between 1.8 and 3.7V.
