Video game player using AVR microcontroller

This work describes the design of this video game player. This video game player is a combination of hardware and software design. The main objective of this project is to develop a low cost and portable video game player. This project consists of hardware and software parts. Hardware involves a digital-to-analog converter to generate the NTSC video signal, a microcontroller ATMEGA8535, microcontroller hardware timers to maintain this signal timing.The components that are being used are ATMEGA8535 as the controller, Joystick as the input and Television as the display. Television monitors is one of the cheapest graphics devices that can be bought which include audio amplifiers and speakers. In this project, the game designed is PINGPONG. The video signal is calculated in real-time by the microprocessor as the electron beam sweeps over the screen. This work was focused on the software generation. The software was coded in C, and much of the code length accounts for video signal generation. The software design controls the look and feel of the game on the screen.
