Breakout on ARM7 LPC2148

Description

We are porting the original game on our 32-bit ARM7 board. We are using a 128x64 glcd. The game has some bricks placed horizontally on upper part of the screen. On the lower part is a paddle. The paddle can move left and right and is controlled by the user. A ball moves across the screen bouncing off the top and side walls of the screen. When a brick is hit, the ball bounces off and the brick vanishes. The player looses half the points when the ball touches the bottom of the screen. The ball can touch the ground 4 times before the game gets over.
The paddle has three parts: left, center, right. If the ball strikes left side of paddle, it gets reflected towards left side and similarly for right side. For center of paddle, the ball moves vertically without any angle.
There are some bomb bricks. If the ball hits bomb brick, it explodes upto 8 bricks in it's vicinity.
There are 2 points for normal brick, 10 points for bomb bricks.

Connected the glcd, two switches to the micro controller board.

Attached a 10K potentiometer to set contrast on glcd.

Implemented a timer(using builtin hardware timers) for precise timings correct to 1 microsecond.

Initialized the GLCD using commands from GLCD datasheet.

Implemented functions to set and clear pixels at arbitrary coordinates on the glcd.

Tested the user input through buttons and all other connections.
