DESCRIPTION OF MAIN SOFTWARE WINDOW
When the software is launched, the main software window
opens (see Figure 14).
The user software panel as shown in Figure 14 has the following
features:
• Menu bar
• Control buttons
• Data capture display
Menu Bar
The menu bar consists of the File and Help menus.
File Menu
Save Data (Acquisition). Saves the position, velocity, and fault
data of a defined number of samples in normal mode into a
spreadsheet file.
Print Front Panel. Prints the software window displayed.
Save as Picture. Saves the front panel as a JPEG file.
Exit. Exits the program.
Help Menu
Analog.com. Opens www.analog.com.
Control Buttons
The E VA L -AD2S1200/05SDZ software includes the following
control buttons, drop-down boxes, and indicators.
Single Acquisition. Initiates the sampling and readback of
the defined number of resolver-to-digital converter (RDC)
measurements.
STOP. Stops the program.
Reoccurring Acquisition. Repeats single acquisition until the
button is released (normal mode).
Flash LED. Causes the orange LED1A on the SDP board to
flash, which can be a useful debugging tool.
Number of Samples. Selects the number of samples to be
completed in a single acquisition.
ON/OFF. Enables or disables the histogram option. (This button
appears on the Histogram Position and Histogram Velocity
tabs only.)
Data Capture Display
In the data capture display, you can select the format in which
to view the position and velocity conversion results. The posi-
tion data can be displayed in digital output code format or in
degrees. The velocity data can be displayed in digital output
code format or in rotations per second (RPS). The desired
display options are selected by clicking on the Acquisition
(Codes), Acquisition (Degrees/RPS), Histogram Position,
and Histogram Velocity tabs.
Acquisition (Codes) Tab
The Acquisition (Codes) tab displays the conversion results
taken in normal mode of the position and velocity of the resolver
connected to the EVA L -AD2S1200/05SDZ board. The number
of conversions results displayed is defined by the Number of
Samples box. The conversion results are displayed as wave-
forms in digital code on two graphs. The upper graph displays
the position conversion results. The lower graph displays the
velocity conversion results. The maximum, minimum, and
mean values of the sample set are displayed on indicators to the
right of each graph.
At the bottom right of each graph are the zoom options. These
allow you to zoom in and out to obtain a closer look at a sample
if required.
Acquisition (Degrees/RPS) Tab
The Acquisition (Degrees/RPS) tab displays the conversion
results taken in normal mode of the position and velocity of
the resolver connected to the EVAL-AD2S1200/05SDZ board.
The number of conversions results displayed is defined by the
Number of Samples box. The position conversion result is
displayed in degrees on the upper graph. The lower graph displays
the velocity conversion results in RPS. The maximum,
minimum, and mean values of the sample set are displayed on
indicators to the right of each graph.
At the bottom right of each graph are the zoom options. These
allow you to zoom in and out to obtain a closer look at a sample
if required.
Histogram Position Tab
The Histogram Position tab displays the histogram of the posi-
tion conversion results taken in normal mode of the resolver
connected to the EVA L -AD2S1200/05SDZ board. To enable this
option, you must set the ON/OFF button to the on position.
The histogram is displayed only when the output code varies for
the one block of samples; that is, if the same conversion result is
returned for all samples, the histogram is not displayed.
At the bottom right of each graph are the zoom options. These
allow you to zoom in and out to obtain a closer look at a sample
if required.
Histogram Velocity Tab
The Histogram Velocity tab displays the histogram of the velocity
conversion results taken in normal mode of the resolver con-
nected to the E VA L -AD2S1200/05SDZ board. To enable this
option, you must set the ON/OFF button to the on position.
The histogram is displayed only when the output code varies for
the one block of samples; that is, if the same conversion result is
returned for all samples, the histogram is not displayed.
Within any of the chart panels, the tools shown in Figure 15
allow user control of the different chart displays.
