SWIPE-STACK is a modern re-implementation of the classic puzzle game Tetris, featuring a wireless glove controller and a dynamic LED-matrix-based main hub.
This project combines embedded systems design, wireless communication, real-time graphics processing, and custom hardware to create an innovative and portable gaming experience.
The system consists of two main components:
- Input Device: A wearable glove capturing hand movements and gestures.
- Key Components:
- IMU Sensor: Collects motion and orientation data.
- STM32 Microcontroller: Processes IMU data and converts it into game control inputs.
- HM19 Bluetooth Module: Communicates inputs wirelessly to the hub via UART.
- LiPo Battery: Powers the glove, with battery management provided by an off-the-shelf controller.
- Game Console: Executes game logic, receives user input, and manages displays.
- Key Components:
- STM32 Microcontroller: Runs the game engine and display drivers.
- HM19 Bluetooth Module: Receives input data from the glove.
- 64x32 LED Matrix Display: Displays the active game screen, driven by a custom parallel interface using DMA and timers.
- OLED 16x2 Text Display: Shows the current score and level via SPI.
- TI Buck Converter: Provides regulated power for the system.
Each STM32 project (Hub/ and Glove/) follows the typical CubeIDE structure, including source files (Core/), drivers (Drivers/), project configuration (.ioc), and build settings.
- Hub/ – Firmware for the main hub (STM32 project using STM32Workbench)
- Glove/ – Firmware for the glove controller (STM32 project using STM32Workbench)
- Electrical/ – Hardware design files (schematics, PCB layouts)
- Mechanical/ – Mechanical design files (CAD models for glove and hub enclosures)
- README.md – Project overview and documentation (this file)
- Wireless Glove Controller: Real-time gesture input using an IMU and STM32 MCU.
- Bluetooth Communication: Low-latency UART-based HM19 Bluetooth link.
- Custom LED Matrix Driver: High-speed, multiplexed driving of a 64x32 RGB LED matrix using DMA and timers.
- Embedded Game Engine: Fully on-board Tetris-like game running on STM32 microcontroller.
- Text-Based Display: OLED screen displaying real-time score and level information.
- Portable and Modular Design: Custom PCBs, enclosures, and battery-powered operation.
