SOFTWARE CONFIGURATION FILES
SOFTWARE DESCRIPTION
Software configuration files give the EVAL-CONTROL BRD2
software information on how the software and hardware should
perform. They contain information such as the name of the
DSP program to download, the default and maximum sample
frequencies, the number of samples to take and the power
supply settings to use. A typical software configuration file
(*.cfg) is shown in Listing 1.

Included in the EVAL-AD7470/AD7472 evaluation board
package is a CD that contains software for controlling and
evaluating the performance of the AD7470/AD7472 when it
is operated with the EVAL-CONTROL BRD2. When the CD
is inserted into the PC, an installation program automatically
begins. This program installs the evaluation software onto the
machine and installs the data sheet for the AD7470/AD7472
evaluation board as well as the data sheet for the AD7470/
AD7472. All literature on the CD is in Adobe Systems Inc.’s
portable documentation format (PDF) and requires Acrobat
Reader™ to be viewed or printed. The user interface on the PC
is a dedicated program written especially for the AD7470/
AD7472.
The software which controls the EVAL-CONTROL BRD2 and
thus the AD7470/AD7472 evaluation board has three main
screens. The dialog box in Figure 4 shows what appears when
the software is running. The main function of the screen is to
allow the user to read a predetermined number of samples from
the evaluation board and display them in both the time and
frequency domain.
