From Hardware to Application: Understanding the Role of HAL in Embedded Platforms
Understand the role of a Hardware Abstraction Layer (HAL) in embedded systems, including peripheral interfaces, hardware integration, performance, and validation. The Hardware Abstraction Layer (HAL) offers software interfaces for hardware resources and separates application logic from a large part of the processor-specific implementation. The effectiveness of this approach relies on the hardware capabilities and on the behaviour required by the application.
