samples to be taken. These samples are then uploaded and
displayed. An FFT and histogram are also calculated and
displayed. If the user clicks Cont Sample, the software repeats
the process indefinitely until the user clicks the button again.
While the software is continuously sampling data the other
control buttons are disabled.
Reset Button
The Reset button causes the EVAL-CONTROL BRD2 to per-
form a reset function. When this happens, the power supplies
to the evaluation board are turned off and the program in the
DSP memory is lost. Repeat the setup instructions to download
another program if required.
Quit Button
The Quit button exits the software; however, the program
running on the EVAL-CONTROL BRD2 is not terminated.
MENU BAR
The main dialog box of the evaluation software contains a
number of options available as pull-down menu items.
File Menu
• Setup Menu: Selecting this option displays the Setup
Menu dialog box as shown in Figure 3.
• Load Raw Data: Selecting this option allows the user to
load data that has been saved by the software during a
previous session.

CONTROL
BUTTONS
• Save Raw Data: Selecting this option allows the user to
save the current set of sample data points. The data can be
reloaded to the evaluation software at a later date or can be
used by other programs for analysis.
• Save Binary Data: Selecting this option allows the user to
save the current set of sample data points. The data is saved
in binary format as a text file. This method can be useful
for examining code flicker and looking for stuck bits.
• Save FFT Data: Selecting this option allows you to save the
current set of FFT data points. FFT data cannot be reloaded
into the EVAL-CONTROL BRD2 software, but can be
loaded into other software packages for further analysis.
• Exit: Quits the program.
Printer Port Menu
This menu item allows the user to select which printer port should
be used for communication with the EVAL-CONTROL BRD2.
• LPT1: Selects 0x378 as the printer port base address. This
is the default option.
• LPT2: Selects 0x278 as the printer port base address.
• PRN: Selects 0x3BC as the printer port base address.
Help Menu
This menu item gives information about the current revision of
software for the particular evaluation board being used.
