Writing Custom Applications
Setup Tab
This tab has a set of controls that hold
the parameters for transmission. These
settings are delivered to the target and
configure the target accordingly. This
tab has several sections.
The Clock section offers configurations
and routing of the clock. The clock for
the FPGA can come from an external
clock or from an internal crystal. The
selection can be made at upper right
corner of this section.
The clock rate of the clock source is
specified in the Output field in MHz.
The Communications section controls
the Alert features and the input data
packets size. Checking the box next to
an alert will allow the logic to generate
an alert if the condition occurs. This
alert can then be left in the data stream,
or extracted to notify the application.
In the Channels section, we can specify
number of channels to activate.
Selecting a channel will flow data from
that data source.
The Trigger selection box controls the way that data streaming is started. It can be started by an external signal or by the
software. Data can also be collected into frames. In this mode a trigger will collect multiple samples before checking the trigger
again. By default trigger source is set to software triggering, though external trigger can be provided once selected.
The Digital I/O field configures the onboard digital I/O. The Data Logging option determines if data streaming stops after
collecting points (a Snapshot of data) or streams forever until manually stopped.
The module supports a test mode for module debugging and system test. The Test Counter Enable is used to turn on test mode
and substitutes a ramp signal with channel number in the upper byte of the data. The Decimation section sets up the decimation
logic to discard data, reducing the incoming data rate.
