Board Support interfaces are used by various example projects to access peripherals that are frequently available on evaluation boards. The Reference section contains a detailed explanation of each Board Support interface API. The Board Support Examples section explains generic example projects that are available for many development boards in greater detail.

The following table lists the usage of the Board Support interfaces by the various example projects. Most example projects are part of the MDK-Professional Middleware.

	Board Support interface is used by the example project.
	Board Support interface is used when the related hardware is available on the evaluation board.
	Board Support interface is not used by the example project.

The Board Support interfaces are board specific and typically part of the BSP section in a Software Pack. To support a new evaluation board it is therefore sufficient to create the easy-to-implement Board Support interfaces.

Many evaluation boards are already supported and are listed on www.keil.com/board2. Once the Software Pack for an evaluation board is installed, the available Board Support interfaces can be selected in the Run-Time Environment. These interface may be also used by user applications or other example projects.
