Hi Ram,
The best place to start would be the VisualDSP++ Getting Started Guide. This provides an overview of the VisualDSP++ toolchain, a basic tutorial on how to create a session and how to build/load/run code, as well as a more advanced tutorial on profile guided optimization (PGO) and the background telemetry channel (BTC).
VisualDSP++ Help also has a wealth of information on how to get up and running with a project. Most of the information you require can be found within the following section:
Help->Contents->Graphical Environment->IDDE->How To
BF527 EZ-Kit examples can be found using the following path in VisualDSP++:
C:\Program Files (x86)\Analog Devices\VisualDSP 5.0\Blackfin\Examples\ADSP-BF527 EZ-KIT Lite
Note, this thread is in the CrossCore Embedded Studio and Add-Ins community. Should you have any further questions on VisualDSP++ please post a thread in the VisualDSP++ community.
Regards,
David.
