Introduction

This 128 X 128 LCD Display Dodger Game has "evil invaders" coming from all corners of the screen and the user must avoid them at all costs. The player can be moved in all 2D directions to dodge invaders using the changes in accelerometer readings of the IMU LSM9DS1. If the player collides with an invader the game ends. This project gives the designer practice using reasonably complex color graphics and interfacing external input/output devices to holistically create a working embedded system.

In this version of the Dodger game, the LCD panel will show you invaders (red squares) randomly coming from any side of the screen.There is also background music that sets the theme of the game. Press the pushbutton to begin the game. The player (green circle) must use the controller (LSM9DS1) to move away from the invaders. If the player collides with the invader the speaker plays a crashing sound and the game ends. To play again you will need to reset the mbed.
