Project Title

Zero Zero UFO

Abstract

Bringing a classic game back to life using Embedded Processors and FreeRTOS will help bring a new take to the basic handheld game. We decided to develop the UFO survival game. The objective is to keep the UFO flying for as long as you can whilst avoiding randomly generated obstacles and the other players ufo. The players will control their respective UFOs with the help of the "Accelerometer" sensor present on the SJone board. The ufo can move in either of these directions; Upward, Downward, Forward, Backward , to avoid crashing. The obstacles will move from Right to Left but the Players' UFOs will stay in the field of vision, i.e. they will always be on the screen. The obstacles will have random spacing and random size, testing the users focus. Player who survives longer wins the Game.

Objectives & Introduction

Primary objective of this project was to write efficient code to develop a game using FreeRTOS. SJOne Boards act as the heart of the project with one acting as the hub and one acting as the wireless controller. The accelerometer sensor on the SJOne board which is connected via I2C is used to register the controller orientation. This orientation is then transferred to the hub using a wireless packet. Once the hub, receives the orientation in the queue, game logic decides wether to move the UFO up or down. The obstacles are generated randomly and are moved from right to left on the LED matrix. If player's UFO collides with any of the obstacles its game over. The speed of obstacle movement increases as the levels goes up.

Game development is a big industry and this project helps us in understanding logic development and manipulating FreeRTOS features to get a good and interesting output. The project includes following modules:

• 1. Wireless Controller: 1 SJOne board is used as the controller. It wirelessly transmits orientation.
• 2. Master Hub: The other SJOne Board is used as the master device. The game logic resides on this board. It is also used to drive the display.
• 3. Display Module: Adafruit 64x64 Led Matrix display is used to display the game. This is driven by the GPIO pins on the master SJOne Board.

The Game

• Wireless UFO game.
• Press switch on controller to start the game.
• Randomly generated obstacles of varying sizes.
• Tilt controller up or down to fly the UFO.

Design & Implementation

This section talks about how the various modules of the project were designed and implemented. The system block diagram is given below. The hardware utilizes 2 SJOne boards and a 64x64 Adafruit LED matrix display.

Wireless Transmitter

HUB

1. Wireless Module

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.

2. Master Module

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.

3.Display Module

LED Matrix Front View

LED Matrix Back View

This is a 64x64 RGB LED Matrix Panel, it has 4096 full-color RGB LEDs in all. Each LED can be independently addressed and controlled. It requires at least 13 digital GPIOs to control the LED matrix. The led matrix has 2 IDC connectors (DATA_IN, DATA_OUT) on the back, you can cascade multiple panels and make a huge screen together. There are two 5*32 decoders used for decoding the address rows. Two 3*64 bit shift registers are used for selecting the colors. This is done by clocking the 64 bit shift registers. There are 5 address lines A,B,C,D,E,F for selecting the rows and R1,G1,B1,R2,G2,B2 for illuminating the leds.
