A complete list of applications examples, operating systems, middleware, and intellectual property (IP) cores are available from Altera and Altera's software tool partners.
Device Drivers for Altera IP and HAL API
Altera provides a complete set of peripheral device drivers and even generates a custom board support package automatically to accelerate your software development effort.
- Hardware abstraction layer (HAL)—Increase your productivity by building your applications on top of the Nios II HAL. The HAL is a well-defined software layer that forms a clear distinction between application and device-level software (refer to Figure 1). The HAL also provides services such as file descriptors, I/O control, and buffering, which are required by the ANSI C library functions, so that your HAL driver does not need to provide these functions. Learn about the HAL System Library (PDF).
- Board support package—The Nios IDE automatically generates a complete board support package, including drivers for the peripherals in your system. Learn about the HAL System Library (PDF).
- Custom drivers—Create your own custom drivers on top of the HAL by leveraging the HAL API using a predefined and well documented driver development procedure. This modular approach promotes consistent, portable, and reusable code. Download Developing Device Drivers for the HAL (PDF).
