TicTacToe

TicTacToe is a 2-player game written in embedded C for CSE2006 project. It runs on Atmel AT89S52.

Hardware

• AT89S52 microcontroller
• LED Matrix
• MAX7219 IC
• SPI IC
• Button grid for input
• Breadboards, jumper cables and batteries
• Arduino (as ISP)

Circuit diagram:

Running

Flash the code onto the microcontroller using a programmer. We followed this blogpost and used Arduino as a programmer.

The buttons in the 3*3 grid act as an input and the visuals is shown on the LED matrix.

Code

• MAX7219.C, MAX7219.h: driver for LED matrix
• game.c, game.h: game logic
• tictactoe.c: application entry point

Look and Feel

The project looks like this!
