The 

Examples

 directory contains the files used in Part 4, Chapter 2, Getting Started with the NI-DSP Interface

Utilities, to build a custom DSP Library.

The 

LIB

 directory contains 

LIBLVDSP.a

, the archived library of object modules containing all of the analysis

functions and Kernel routines used in building the downloadable DSP Library files, as well as the two DSP
Library files 

LV2200S.out

 and 

LV2200.out

.

For instructions on installing the NI-DSP Interface Utilities, refer to Part 1, Getting Started with NI-DSP, under
the section titled Installing NI-DSP for LabVIEW for Windows.

For instructions on installing the AT&T WE DSP32C software, refer to the WE DSP32C Support Software Library
User Manual and other related documentation.

Use the NI-DSP Interface Utilities to customize the DSP Library and execute your own functions on the DSP board.
Figure 1-2 shows a diagram of the interface layers used to access functions in your custom library.

Figure 1-2.  Interface Layers to Onboard Functions

When your library is downloaded and a LabVIEW interface to your function has been created, you can execute a
function in your onboard custom library by making a call to the interface function in your program from LabVIEW.
This call passes control to the interface software which calls the NI-DSP driver.  The NI-DSP driver communicates
with the DSP Library to pass parameters, indicates which onboard function to execute using the dispatcher, and
returns results to LabVIEW.
