 # STM32 software
+The game engine will be designed to support 2D games. The engine will use a state machine to manage game states and transitions between them. The state machine will be implemented using a finite state machine (FSM) design pattern. The engine will also include support for handling user input, game logic, and sound.
+
+FSM is a useful tool for managing game states and transitions. A game can have many different states, such as a title screen, a level selection screen, a loading screen, and various gameplay states. Each state represents a particular configuration of the game, with different sets of variables, objects, and logic
+
+The state machine will be designed with the following states:
+1.	Initialization: The initialization state will be responsible for initializing all game-related variables and subsystems, including the FPGA-based picture processing unit.
+2.	Title Screen: The title screen state will display the game's title screen and wait for user input to start the game or access the options menu.
+3.	Options: The options state will allow the user to configure game settings, such as sound and graphics options.
+4.	Game Play: The game play state will be responsible for running the game logic and updating the game state.
+5.	Game Over: The game over state will display the game over screen and wait for user input to restart the game or return to the title screen.
