SW Overview
The software supplied with the HSP3824 evaluation kit
makes it easy to configure the board. Upon program startup,
the user is presented with a “tabbed-notebook” containing
eight “pages.” Each page represents a logical grouping of
various control and status registers in the HSP3824. The
desired page is made active by selecting the tab associated
with that page. Once changes are made to the components
on the screen, these values must be downloaded to take
effect. The pages are:
Preamble/Header
Components on this page include preamble generation,
transmit modes and receive modes.
Modem Configuration
Components on this page include configuration for
transmitter and receiver. The master clock contained on this
page is used to calculate and display in “real-time” the
transmit and receive symbol rates. Scrambler configuration
and antenna operation are also contained on this page.
I/O Configuration
Components on this page include configuration of active
signal levels (polarity) of HSP3824 I/O signals and setup of
other miscellaneous I/O signal parameters.
Test Port Configuration
This page contains the configuration component for
selection of internal HSP3824 signals and/or data to become
available to the evaluation board Test Port pins.
Threshold Settings
Components on this page include a number of configurable
threshold settings. It covers Received Signal Strength
Indication and Clear Channel Assessment configuration
registers, as well as received signal quality thresholds used
during acquisition and data tracking.
A/D Calibration
Components on this page include configuration data to
activate the A/D level adjustment circuit of the HSP3824.
Modem Status
Components on this page represent modem status (read-
only) registers. These modem status components are
updated approximately once per second.
Signal Status
Components on this page represent both control and status
registers. The status components have a green background
to discriminate them from control components. Components
on this page include preamble information, received signal
quality indicators and signal field configuration.
Other Status
In addition, there is a status area in the lower left corner of
the main screen. The status display contains:
Current Time
Current Communication (Printer) Port
Currently Active Board
Chip Detected (PN Acquisition)
On the bottom right of the screen are several shortcut
buttons. The buttons are:
Configure Button
This button calls up the configuration dialog box.
Download Button
This button downloads (with verification) the current control
register values.
Exit
This button exits the Evaluation program.
Software Controls
There are several basic types of components within the main
tabbed notebook. Each of these components represents a
bit field contained within one or more HSP3824
control/status registers. The component types are:
Radio Button Groups
These components allow the user to make a single selection
from a set of choices (typically from 2 to 16 selections).
Decimal Numeric Fields
These components allow the user to specify a decimal
number.
Hexadecimal/Binary Numeric Fields
These components allow the user to specify either a
hexadecimal or a binary number. The Evaluation Board
software keeps the related field synchronized with the data
entry field as data is being entered.
Check Boxes
These components allow the user to make a Yes/No choice.
Components which are not valid or meaningful for a specific
configuration are “dimmed-out” and cannot be selected.
Status fields are polled and updated approximately once per
second.
Status (read-only) fields which are numeric in nature (i.e. the
Signal Status page) have a green background. A numeric
status field will not update if it has focus. To resume
updating, move the focus to a different component.
