My home made evaluation board used in most of my AVR projects. The different parts are from left to right and from top to bottom: AVR programmer (STK200 clone), adapter for AT90S8535 and ATMEGA163, LCD display (20x4 characters), Nokia graphical LCD, adapter for AT90S2313, connector for the LCD display, RF-modulator (from an old cable TV decoder), LEDs, Keypad. Most of the modules are however not used in this project.

Close up on the programmer and the AT90S8535/ATMEGA163 adapter. These two modules together does the same job as an STK200 programmer from Atmel. The keypad and the scart connector described below is the only external hardware neccesary for the video game console.
|
The video game setup. Since my old mini-TV does not have a scart input, an RF modulator is necessary to convert the the composite video signal to a UHF modulated signal. The RF modulator is not necessary if a scart connector is used.
|
Close up on the break out game in action. The camera is not fast enough to catch a single frame of the video sequence. Therefore the ball and the paddle are double exposed.
|
The simple DAC consisting of 5 resistors can easily be put inside the cover of the scart conector. A connection diagram is provided in video.h in the code section.
