What This Course Covers

Firmware Architecture Fundamentals

• Overview of why modular firmware matters for portability and maintainability.
• Comparison of bare‑metal coding versus architected solutions.
• Key principles of layered software design in embedded systems.
• Real‑world examples of architecture failures and how to avoid them.

The 4‑Layer Framework

• HAL (Hardware Abstraction Layer): Hiding silicon specifics behind clean APIs.
• Device Layer: Building reusable drivers for sensors, LCDs, and communication modules.
• Interface Layer: Defining contracts between hardware and business logic.
• Application Layer: Writing pure, hardware‑agnostic code that scales across projects.

Embedded C Coding Standards

• Detailed walkthrough of the Embedded C Coding Standard used in the course.
• Enforcing “Yoda conditions” and naming conventions for readability.
• Techniques for eliminating magic numbers and improving code safety.
• Automated linting and static analysis tools integration.

Interface Pattern & Modular Design

• Implementing the Interface Pattern to achieve loose coupling.
• Designing modular APIs that simplify testing and future extensions.
• Strategies for versioning and maintaining backward compatibility.
• Hands‑on exercises refactoring legacy code into modular components.

Professional Starter Kit & Tools

• Building a “Professional Starter Kit” template for rapid project kickoff.
• Setting up project structure with Init, Callback, and Global modules.
• Using GitHub Copilot to generate boilerplate while adhering to standards.
• Exporting the template to GitHub for collaborative development.

Who Should Take This Course

• Intermediate Embedded C developers seeking to adopt professional architecture practices.
• Senior firmware engineers who need a standardized, portable codebase for multiple MCUs.
