AVR Game Console Using Embedded Entertainment System

The project uses the Embedded Entertainment System (EES) in order to create a fully featured and simple game system based on AVR.

Different tasks such as sound effects, IR receiver decoder, and generating composite video signal are being performed by this project as it uses 3 AVR microcontrollers. A simple monochrome image on TV screen is being generated by the game along with the playing of monophonic sound. To have an additional control for joystick, a dual axis Memsic 2125 accelerometer is also featured.

Four chips are used to have the video game system working. An ATmega168 is used for the wireless controller while the three ATmega328P microcontrollers are used for video, monophonic sound, and for receiving information remotely from the IR LED in the controller. all the microcontrollers are running at 14.7456 MHz except the microcontroller for video which runs at 16MHz.

There are two resistors, 470R and 4.7K, used for the composite video to keep it simple since most of the projects for composite video uses several resistor-based voltage divisors to produce a stable image on the screen. For the IR motion controller, a 38kHz PWM is being used.
