Embedded application software development and embedded system software development are two related but slightly different concepts:
Embedded application software development is primarily concerned with the development of a specific application program that runs in an embedded system. It involves writing application code that implements specific functionality and logic and interacts with embedded hardware. Embedded application software is usually developed to fulfill specific needs and application scenarios, such as home appliance control systems, medical device control, etc. Developers need to be familiar with programming languages, algorithms and related domain knowledge.
Embedded system software development is more bottom-level, focusing on the operation and management of embedded systems. It includes the development and maintenance of operating systems, device drivers, communication protocols, file systems, and so on. Embedded system software is responsible for managing hardware resources, providing abstraction layers and interfaces, and enabling applications to run on embedded systems. Developers need to understand the underlying hardware architecture, operating system principles and driver development.
In general, embedded application software development pays more attention to the function and logic of the application layer, while embedded system software development pays more attention to the underlying system management and hardware operation. The two work closely together to ****together build the complete functionality of an embedded system.
