Summary
A project about mixing classic 2D games in a single one on Raspberry Pico, having 2048 in the main stage.

Description
The objective of the project is to show the knowledge gained throughout the semester by making functional hardware that runs games written in Rust. Starting with a 2048 games, it can be very fast changed to Tetris, creating more fun for the player.
Motivation
For many years I loved playing games, even it is not in a computer. While trying to prove what I learn this semester about Rust and hardware, I wanted to show that anyone can create a game on anything that has electricity.
Arhitecture
Log
Week 28 April - 4 May
Forked the project and started the documentation. Added the bill of materials and the software most likely used.
Week 5 May - 11 May
Week 12 April - 18 May
Week 19 April - 25 May
Hardware
This project is using the following components:
- 2x Raspberry Pi Pico 2W for controlling the display and the results intented while pressing the buttons;
- 1x 1.8" SPI LCD Module (128 x 160) to display the game;
- 5x push buttons (4 for movements, 1 to change / reset a game).
Schematics
Will be displayed soon.
Bill of materials

| Micro USB 1 m Black Cable | 1 | Power and programming for a Pico | 6,95 lei |
Software
This is not final. This is most likely what I'll use after I get the last order of components which are missing.
| Crate | Description | Usage |
|---|---|---|
| rp2040-hal | Hardware Abstraction Layer for the RP2040 microcontroller | Direct access to GPIOs, UART, SPI, I2C, timers, PWM, etc., on the Pico |
| embedded-hal | Standard traits for embedded peripherals (e.g., digital I/O, SPI, I2C) | Foundation for cross-platform driver development and HALs |
| panic-halt (or) defmt | panic-halt: minimal panic handler; defmt: logging and debug output | Handling panics or enabling real-time logging/debugging |
| embedded-graphics | 2D graphics primitives for displays (no-std) | Drawing shapes, text, images on the LCD |
| st7735-lcd | Driver for ST7735-based SPI displays | Communicating with and rendering to the 1.8" SPI LCD module |
| heapless | Fixed-capacity data structures with no heap allocation | Queues, buffers, or hash maps without dynamic memory |
| cortex-m | Low-level access to ARM Cortex-M processor features | Accessing special registers, enabling interrupts, etc. |
| cortex-m-rt | Runtime support for Cortex-M processors | Defines the entry point, vector table, and startup code |
| [usb-device](https://crates.io/crates/usb-device | ||
| ) | USB device stack for embedded systems | Creating USB peripherals (e.g., serial communication over USB) |
