User Guide¶

Welcome to the Nexus Platform User Guide. This comprehensive guide covers everything you need to know to effectively use the Nexus embedded platform in your projects.

Overview ¶

The Nexus User Guide is organized into several sections, each covering a specific aspect of the platform:

Core Architecture: Understanding the fundamental design and structure of Nexus
Hardware Abstraction Layer (HAL): Working with hardware peripherals through unified APIs
OS Abstraction Layer (OSAL): Managing tasks, synchronization, and RTOS integration
Framework Components: Using high-level services like logging, shell, and configuration
Configuration System: Mastering Kconfig for compile-time configuration
Build System: Understanding CMake build configuration and customization
Platform Integration: IDE setup, debugging, and platform-specific features
Advanced Topics: Power management, security, performance optimization
