5 LABVIEW INTERFACE
The Labview interface is presented as seven virtual instruments: one to load the Sundance hardware, three
to get data from the DSP application, and three to send data to the DSP application. These instruments
appear as User Libraries in the Labview Functions palette. You can display this palette by going to the
Block Diagram window and selecting View/Functions Palette.
From DSP is a folder with the three input instruments and To DSP is a folder with the three output
instruments. LOAD DSP.vi is the instrument used to send an application to the Sundance hardware.
The “get_...” instruments receive data from the DSP application in the form of arrays of values of the
selected type; the size of array is determined by the DSP. For example, get_int.vi returns an array of
32-bit integers.
The “put_...” instruments send arrays of the selected type to the DSP application. For example,
put_float.vi sends arrays of 32-bit floating point values. The size of array transmitted must match
the expectation of the receiving DSP code.
