TinyPiXOS includes four main parts: a window manager (TpWM), core library (TpCore), GUI library (TpGUI), and utility library (TpUtils). --- # 1. Project Overview 📚 **TinyPiXOS** is built on open-source Linux. Through innovative kernel-level lightweight refactoring and streamlined design, it abandons traditional graphics stacks such as X11/Wayland. Using pure C/C++, it rebuilds an ultra‑lightweight end-to-end graphics stack from the ground up—including efficient window management, a minimal GUI framework, and deeply optimized kernel mechanisms. TinyPiXOS signifies a self-owned, complete foundational stack built from scratch. Its core positioning is to provide an embedded desktop OS development platform that is **independent, lightweight, and highly customizable**. **Core goals:** With minimal hardware resources, ensure smooth multi-application concurrency and deliver complete desktop-grade core capabilities (resource management, peripheral drivers, graphics rendering, etc.). ## TpWM TpWM is the window management engine of TinyPiXOS and a core pillar of the system. The engine focuses on minimal, streamlined interfaces, discarding redundant complexity. Inspired by RISC-style minimal instruction sets, it offers window designers flexible building blocks for free composition, enabling highly customizable products with diverse behaviors. ## TpService TpService is TinyPiXOS's background service module, built on nanomsg for efficient messaging. It currently provides inter-process communication (IPC) and LAN device communication, and will gradually expand into more powerful system service nodes. ## TpCore The TpCore library is the core library for TinyPiXOS applications. It provides signals/slots, fundamental data structures, file operations, JSON processing, and generic types. --- - Unified data abstraction: TpString, TpList, TpHash, TpVector serve as common container base types across the framework, building a unified data structure system to ensure type safety and memory efficiency. - Efficient serialization: Unified conversion between binary and JSON formats, supporting fast transforms between structs and memory buffers for high-performance storage and transport. - Event-driven scheduling: Built-in signals/slots based on the observer pattern enable loosely coupled component communication with async event propagation and callbacks. --- ## TpGUI The TpGUI library provides the core GUI framework for TinyPiXOS applications. It implements a comprehensive widget-based UI system with CSS styling, event handling, and animation. TpGUI is the foundation for building graphical applications on TinyPiXOS. --- - Unified object management: `TpObject` acts as the common base class across modules, establishing a unified object lifecycle management system for rigorous resource handling. - Efficient event dispatch: Unified processing and propagation of user input and system events. - Smart memory management: Automatic or semi-automatic widget memory handling reduces risk of leaks. - Rendering scheduler: Optimized drawing pipeline coordinating component update order to ensure smooth UI. - Declarative styling: Powerful stylesheet system enables fast, declarative customization of widget look and overall UI themes, avoiding hard-coding. --- ## TpUtils The TpUtils library provides comprehensive system-level integration capabilities for TinyPiXOS applications. It bridges high-level application logic and low-level system resources, offering standardized interfaces for media processing, network communication, Bluetooth connectivity, application lifecycle management, hardware monitoring, and device management. --- - Unified media processing: `TpAudioOutput` and `TpVideoOutput` provide a unified abstraction layer for A/V, integrating FFmpeg codecs and supporting efficient playback and recording of multi-format media. - Device management: `TpDiskManage` and `TpUsbManager` auto-detect and mount hot-plug devices, with signal-driven notifications for state changes to reduce peripheral management complexity. - High-performance networking: Built-in TCP/UDP socket framework with standardized interfaces (`TpTcpSocket`, `TpUdpSocket`, `TpTcpServer`), supporting async event-driven connection management and data transfer. - Bluetooth stack: Based on BlueZ, supports full device pairing, audio transport, and file exchange; `TpBluetoothLocal` and `TpBluetoothAudioManager` provide declarative device management APIs. - Application lifecycle: `TpAppInstall` and `TpAppDopack` implement sandboxed app installation, supporting permission control, dependency injection, and cryptographic signature verification for security. - System resource monitoring: `TpCpuManage`, `TpMemory`, and `TpDiskManage` collect CPU/memory/disk I/O metrics in real time to support performance optimization. - Display system integration: `TpDisplay` provides DPI scaling and resolution adaptation with the `TpWM` window manager, supporting multi-monitor setups and runtime resolution switching. --- # 2. Key Advantages 🌟 - Independent and controllable: In-house TpWM window manager and GUI framework; no dependency on X11/Wayland. - Lightweight and flexible: Modular architecture with on-demand trimming, optimized memory and process scheduling, extreme resource efficiency; deployable from tiny embedded devices to high-performance mobile terminals. - Heterogeneous compatibility: Unified C/C++ APIs with seamless migration across ARM/x86/RISC-V platforms. - Ready to use: Built-in UI component library accelerates application development. - Long-term maintenance: Dedicated technical team ensures ongoing support and updates. - Chinese support: Friendly Chinese text rendering throughout the system. - Free for commercial use: Free to use commercially (retain copyright notice); enterprises can build customized systems at low cost to accelerate product delivery. --- # 3.

Open-Source Goals 🎯 As a desktop operating system targeting lightweight hardware platforms, **TinyPiXOS** features a complex architecture and numerous functional modules. While the current version provides foundational capabilities, it still needs community contributions to mature. We open source the core framework to aggregate developer wisdom and co-build a domestic embedded OS ecosystem. - Co-build a domestic foundation: Use TpGUI and other core modules as the base to jointly create an independent, controllable embedded development ecosystem. - Inclusive co-creation: The current version may have shortcomings; please provide constructive feedback from a developer perspective so we can improve together. - Create unlimited possibilities: Encourage innovative applications built on the open-source framework; outstanding projects will receive official technical support. - Ongoing commitment: The core team will maintain the desktop and application ecosystem long term, releasing key updates regularly. --- # 6.
