2048

Two Zero Four Eight (2048) is a game having a grid of numbered tiles (i.e., power of 2) to combine them to create a tile with the number 2048. It is usually played on a 4x4 grid with tiles that slide smoothly when a player moves them towards right, left, up or down. Every time a new tile will randomly appear in an empty spot on the display with a value of either 2 or 4. If two tiles of the same number collide then they will merge into one tile with value of sum of those two tiles. Game continues until no merge is possible.

Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Hardware Design

Discuss your hardware design here. Show detailed schematics, and the interface here.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Software Design

Software Design Block Diagram

There are four modules in the software design: Game Logic, Output Interface, Input Interface and the FreeRTOS tasks. When the board boots up, user is given option to select the Input type (Joystick/Accelerometer). An application interface to the selected input device is given to the Game Logic. Two FreeRTOS tasks are created to run the Game Logic and update the display. Game Logic manipulates the game grid, by taking direction as the input through the Input Interface. It invokes the Display Application to dump updated data onto the LED Matrix display.

Testing & Technical Challenges

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Include sub-sections that list out a problem and solution, such as:

<Bug/issue name>

Discuss the issue and resolution.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?

Philosophy

Following are some philosophical renditions of the concepts we have learned in this wonderful class. This is partly inspired by The Zen of Python and mostly by our constant quest for knowledge.

Priorities are very important; set them correctly.
