ATmega32 8 Bit Game Circuit LCD Joystick

The game console is made up of an Atmel ATmega32 processor, comprising 32kB Flash program memory, 1kB EEPROM memory and 2kB SRAM memory. Next is the console consisting of an LCD display and a speaker. To the console for ease of maneuverability games joins the joystick.

This is a 64×128 pixel LCD. Available under different names (ATM12864, PG12864) and in different color backlight (blue, white, green-yellow) This LCD contains two separate controllers, each of which controls one half display, so the area of 64×64 points. Each half contains eight more pages. At therefore, not every single point is written on the display, but flats are plotted in rows (pages)

The joystick is used for easy and intuitive game control. It connects by using 15-pin CAN connector to the side of the bracket. It contains 12 buttons, of which two quads are designed as directional buttons, the other two buttons on the top side for shooting or confirmation, and the Start and Exit buttons.

Speaker For even greater game play experience, music on their backgrounds is inherent components of the game. For this game console, we only have to do with a rectangular signal, which is generated by a counter / timer 0 at frequencies from a large octave (from 65,406 Hz) after twin octave including (up to 1,975,533 Hz), see . The processor is capable to generate tones of higher frequencies, but this is unnecessary. Each note has its own frequency and length, the frequency is then presented by a unique register setting timer 0 and the length of the delay in which this frequency is generated. Generating the audio signal is at the PB3 terminal to which the volume control trimmer is connected sound and a miniature speaker is connected to it.

This AVR game work deals with the creation of several game applications for an 8-bit console made by the AVR ATmega32 microcontroller. Similar topics (programming games for AVR processors) is also concerned with the Uzebox project. It is also a game console, emulator on NES-SNES console (Nintendo Entertainment System Super Nintendo Entertainment System), with an 8-bit AVR ATmega644 processor. Uzebox uses two NES-SNES joysticks to control the games and uses S- video, SCART) or monitor. Due to the lack of functional joysticks I have NES-SNES decided to join the joystick himself. Because the gaming console is constructed as portable device of small dimensions and rendering on television loses importance, is for screen display. I enjoyed playing games like this in my youth and I have been interested in programming for a long time, so I wanted to combine these two hobbies. The following chapters describe itself gaming console, rendering on the display, joystick description, and sound creation speaker. Furthermore, the individual applications, their basic nature, control, rendering. This is a mining application, well known from the table computers, and it is the most successful game of all time Tetris and the third application is Spaceman, similar to mobile phone games.
