Create and Deploy a Sample Waveform

This section describes the process of creating a waveform, deploying this waveform to the staging area, starting a Domain Manager and a Device Manager, creating an instance of an application representing this waveform, releasing the application, and shutting down the Domain Manager and Device Manager.

The Domain Manager and Device Manager normally remain running during the creation/destruction of different applications.

Create a Sample Waveform

Below is a description of how to create a waveform:

  1. Select File > New > REDHAWK Waveform Project

  2. Set the Project name to demo

  3. Select Finish

This opens an editor on the demo.sad.xml file.

To add components to this waveform:

  1. Select the Diagram tab.

  2. In the Palette, drag the SigGen component onto the diagram.

  3. In the Palette, drag the HardLimit component onto the diagram.

  4. Drag a connection between the SigGen_1 dataFloat_out port and the HardLimit_1 dataFloat_in port

  5. The waveform looks like :

    Demo Waveform
    Demo Waveform

  6. If SigGen_1 does not have a yellow 0, right-click the component and select Set As Assembly Controller

  7. Press Ctrl+S to save or select File > Save.

  8. Close the Waveform Editor by selecting the X or by selecting File > Close All.

Export the Waveform

Below is a description of how to export the waveform in the IDE:

  1. In the Project Explorer view (typically on the left-side) select demo

  2. Drag the demo project onto the Target SDR in the REDHAWK Explorer view.

This installs the waveform into $SDRROOT/dom/waveforms. If a permissions denied error is encountered, ensure that the $SDRROOT is set up per the installation instructions in Installing the Framework from Source.

Verify that the waveform is installed:

  1. In the REDHAWK Explorer view, expand Target SDR.

  2. Expand Waveforms.

  3. Verify that the demo waveform is shown.

Run the Waveform on the Runtime Environment

This section provides an overview of how to launch a waveform as an application and release an application.

Launching a Domain

Begin by starting a Domain Manager and Device Manager.

Launch the Waveform

  1. In the REDHAWK Explorer view, right-click the REDHAWK_DEV domain connection.

  2. Select Launch Waveform…

  3. Select the demo waveform, then select Finish.

  4. To start the waveform, select the Start Waveform (green triangle) button in the toolbar.

This opens the waveform explorer. A waveform is displayed in the REDHAWK Explorer by expanding the REDHAWK_DEV domain connection and the waveforms folder.

Open a Plot

  1. Left-click the dataFloat_out port to select it.

  2. Right-click the port to open the port context menu.

  3. Select Plot Port Data. This opens a plot showing the plot data.

  4. To clearly view the sinusoid wave in the plot, reduce the frequency produced by SigGen.

  5. Open the Properties view and change the frequency property to a value of 50.

Stop and Release the Application

  1. Select the Stop Waveform (red square) button in the toolbar. The plot stops updating.

  2. Select the Release Waveform (red X) button in the toolbar. The waveform explorer closes.

Shutdown the Domain

Finally, shutdown the Domain Manager and Device Manager.
