12. Application Programming Interface (API) and Final Application
The chapter discusses Application Programming Interfaces (APIs) as essential tools in embedded systems development, highlighting their ability to simplify hardware interactions and enhance code portability. It categorizes types of APIs including hardware abstraction, operating system, middleware, and peripheral driver APIs, each serving distinct functionalities in an embedded context. Furthermore, the chapter details the structure, integration, testing, and optimization of APIs within final applications, demonstrating their role in efficient embedded system design.

What we have learnt
- APIs provide a standardized way for components to communicate, minimizing the need for detailed hardware knowledge.
- Various types of APIs exist to abstract hardware, manage operating system tasks, facilitate middleware operations, and control peripherals.
- Optimizing APIs and applications is crucial for achieving desired performance, power efficiency, and memory management in embedded systems.
Key Concepts
- -- Application Programming Interface (API)
- A set of protocols and tools that enables different software components to communicate with each other.
- -- Hardware Abstraction
- APIs that simplify hardware interaction by hiding low-level details from the developer.
- -- RealTime Operating System (RTOS)
- An OS designed for real-time applications that deliver timely responses.
- -- Middleware API
- APIs that provide higher-level services to simplify development tasks like networking and data serialization.
- -- Unit Testing
- The process of testing individual components of a software application to verify their correctness.
