51 MCU + LCD12864 LCD Tetris game, proteus simulation, ad schematic diagram, code, thesis, etc

The design requirements
（1） utilize 51 Single chip microcomputer , Design a Tetris game , Complete the development of hardware circuit and the compilation and debugging of program ;
（2） use LCD12864 LCD as the game running interface ;
（3） Use the flexible input and deformation control of the box ;
（4） Can prompt the player the shape of the next box , Show game score 、 Game timing and so on ;

System Overview
This paper designs a software based on AT89C51 Tetris game console with single chip microcomputer , The whole system is divided into hardware and software .

The hardware part consists of a power module 、 Minimum system of single chip microcomputer 、LCD12864 Display module and independent key module . The software part is based on C Language development , To complete the logic design and algorithm design of the game . The system block diagram is as follows .

The basic function of this design is , The single chip microcomputer outputs randomly at the upper end of the display screen 7 There are different types of square graphics （ Long strip 、Z The font 、 back Z shape 、 Field shape 、7 The font 、 back 7 shape 、T The font ）, And make the square fall at a uniform speed to fill the given area .

In the process of falling , Players through the keyboard （ On 、 Next 、 Left 、 Right click ） Transform the block 、 Move down 、 Move left and right . When the box fills one or more lines, it cancels the line score , Until the blocks pile up at the top of the display and can't be eliminated , The game is over .

Analysis of simulation results
Open Tetris simulation （ File for ： Tetris simulation .DSN）, Double click the MCU to load Game.hex file （ be located C In the program folder ）, Run the simulation , The results are shown in the following figure .

LCD12864 The top of the left screen randomly generates a square shape and drops ;LCD The right screen shows ： Prompt the shape of the next box 、 Game score （SCORE）、 Game timing and so on .

Players can press four buttons , Transform the block 、 Move left 、 Move right and down . When the box fills one or more lines , Cancellation score . The figure below shows , The game is running 1 branch 47 second , Players score 2 branch .

When the blocks pile up at the top of the interface and cannot be eliminated , Game over . here , The game interface displays Game Over, After a short wait , Start a new round of game .

in summary , tetris Proteus The simulation can run normally , Meet the design functions and requirements , The expected effect of this design has been achieved .
