This repository contains the Momentum firmware for a multi-protocol wireless device (Flipper Zero). It implements a modular embedded operating system with hardware abstraction layer (HAL) for STM32 microcontrollers, supporting NFC, Sub-GHz, infrared, iButton, GPIO, Bluetooth, and USB protocols. The firmware features a scene-based UI framework, service-oriented architecture (power, storage, GUI, notification), plugin system for extensibility, and JavaScript scripting capability. Key architectural patterns include resource management via furi_record, event-driven communication using Furi's kernel primitives, and consistent GUI module design. The codebase demonstrates strong embedded systems craftsmanship with clear separation of concerns, reusable components, and active maintenance.
