<h2>1: Workspaces</h2>
|
|
|
|
The different component windows are arranged freely in the MDI (Multiple Document Interface) area of the workspace. Any number of workspaces can be added that will stack upon each other by default and can be put forward using the side tabs (1). The workspace index appears on the left of the workspace top bar (2):
|
|
|
|
|
|
|
|
The different component windows are:
|
|
|
|
- [Device](device/readme.md) to interface and control a physical SDR hardware device connected to the system
|
|
- [Main Spectrum](mainspectrum/readme.md) to show the spectrum of the baseband related to the device
|
|
- [Channel](channel/readme.md) to control a channel plugin
|
|
- [Feature](feature/readme.md) to control a feature plugin
|
|
|
|
The workspaces are attached to a docking area of the main window and can be undocked to be moved to another display in a multiple screen setup for example.
|
|
|
|
The workspace has a top bar with the following controls:
|
|
|
|
|
|
|
|
<h3>1.1: Workspace index</h3>

<h3>2.2: FFT</h3>
|
|
|
|
When clicking on the FFT submenu a dialog opens for running the `fftwf-wisdom` utility with a choice of direct and possibly reverse FFT sizes. It produces a so called wisdom file `fftw-wisdom` that speeds up FFT allocations. It is created at a default location and will be used at next invocations of SDRangel.
|
|
|
|
|
|
|
|
<h4>2.2.1: FFTW Wisdom program</h4>
|
|
|
|
Path to the `fftwf-wisdom` program. It looks in the `PATH` variable and the "current" directory (that is the same directory where the `sdrangel` binary resides).
|
|
|
|
<h4>2.2.2: Select FFTW Wisdom program</h4>
|
|
|
|
Opens a file selection dialog to look for the `fftwf-wisdom` program.
|
|
|
|
<h4>2.2.3: FFT maximum size</h4>
|
|
|
|
Select the maximum FFT size for precomputation. Sizes are powers of two between 128 and 32k.
|
|
|
|
<h4>2.2.4: Reverse FFT</h4>
|
|
|
|
Select this checkbox to cover reverse FFTs
|
|
|
|
<h4>2.2.5: Command line</h4>
|
|
|
|
This is the command line that will invoke the `fftwf-wisdom` program with its options
|
|
|
|
<h4>2.2.6: OK: launch the FFTW wisdom program</h4>
|
|
|
|
When clicking the "OK" button the `fftwf-wisdom` program is launched in the background. A message pop-up appears with the PID of the process and the dialog exits. A new pop-up will appear with the output content when the program completes.
|
|
|
|
<h4>2.2.7: Cancel: dismiss the dialog without execution</h4>
|
|
|
|
When clicking the "Cancel" button the dialog is dismissed without execution of the `fftwf-wisdom` program.
|
|
|
|
<h3>2.3: Commands</h3>
|
|
|
|
This is a tree view of the saved commands. Commands describe the path to an executable file, its arguments a possible link to a keystroke event that triggers the execution. Similarly to presets commands can be arranged into groups and have a description short text.
|
|
|
|
Typically an "executable file" is a script (Python, shell, whatever...) or can be a compiled program (c, c++, java, whatever...) that interacts with SDRangel using its web REST API. When called from within SDRangel they can act as "macros" allowing to perform actions automatically.
|
|
|
|
Of course any binary that resides in your system can be used that way like `/bin/ls` or `/bin/date` although these two are of anecdotal interest...
|
|
|
|
|
|
|
|
<h4>2.3.1: Command selection</h4>
|
|
|
|
You select a command or a command group by clicking on its line in the tree view. All actions (6) will be done relative to this command or command group.
|
|
|
|
<h4>2.3.2: Group</h4>
|
|
|
|
You can organize your commands into groups. Groups can be collapsed or expanded by using the caret icon on the left.
|
|
|
|
<h4>2.3.3: Description</h4>
|
|
|
|
Short description of a command.
|
|
|
|
<h4>2.3.4: Key binding indicator</h4>
|
|
|
|
- `-`: no key binding
|
|
- `P`: key press binding
|
|
- `R`: key release binding
|
|
|
|
<h4>2.3.5: Key binding sequence</h4>
|
|
|
|
This is a descriptive text of the key sequence that is used for the key binding.
|
|
|
|
<h4>2.3.6: Command control or actions</h4>
|

|
|
|
|
This dialog will show the results of the last run including the output (merged stdout and stderr).
|
|
|
|
|
|
|
|
<h6>2.3.6.5.1: Process status</h6>
|
|
|
|
When the process is not running the stop icon (■) is displayed. The background color indicate different states:
|
|
|
|
- no color (same as background): the process has never run during this session
|
|
- red: the process ended with error
|
|
- green: the process ended successfully. This does not mean that there was no programmatic error.
|
|
|
|
When the process is running the play icon (▶) is displayed with an orange background.
|
|
|
|
<h6>2.3.6.5.2: Refresh data</h6>
|
|
|
|
Pushing this button will update the data displayed with the latest status. Please note that the log is displayed only when the process is terminated.
|
|
|
|
<h6>2.3.6.5.3: Start time</h6>
|
|
|
|
This is the timestamp of process start. It is filled with dots `...` if the process has never started during this session.
|
|
|
|
<h6>2.3.6.5.4: End time</h6>
|
|
|
|
This is the timestamp of process end. It is filled with dots `...` if the process has never terminated during this session.
|
|
|
|
<h6>2.3.6.5.3: PID</h6>
|
|
|
|
This is the process PID. It is 0 if the process has never run during this session.
|
|
|
|
<h6>2.3.6.5.6: Process kill</h6>

|
Use this button to kill (send SIGKILL) the running process. It has no effect if the process is not running.
|
|
|
|
<h6>2.3.6.5.7: Command line</h6>
|
|
|
|
This shows the actual command line that was used to start the process
|
|
|
|
<h6>2.3.6.5.8: Error status</h6>
|
|
|
|
This is the translation of `QProcess::ProcessError`. Possible values are:
|
|
|
|
- `...`: the process has never run during this session
|
|
- `Failed to start`: the process could not start. For example the executable file has no execution rights actually
|
|
- `Crashed`: the process ended with crash. This is the status when you killed the process
|
|
- `Timed out`: the last waitFor...() function timed out.
|
|
- `Write error`: an error occurred when attempting to write to the process. For example, the process may not be running, or it may have closed its input channel.
|
|
- `Read error`: an error occurred when attempting to read from the process. For example, the process may not be running.
|
|
- `Unknown error`: an unknown error occurred.
|
|
|
|
<h6>2.3.6.5.9: Exit code</h6>
|
|
|
|
This is the program exit code. When the process crashes this is the signal by which the process end was caused. For example if you kill the process with button (6) it sends the process a SIGKILL (code 9) and therefore the value is 9.
|
|
|
|
<h6>2.3.6.5.10: Exit status</h6>
|
|
|
|
There are only two possibilities: either the program exits normally but possibly with a non zero exit code or it ends with a crash.
|
|
|
|
<h6>2.3.6.5.11: Process log</h6>
|
|
|
|
This is the log of the process (merged stdout and stderr). Please note that it is updated only on program termination.
|
|
|
|
<h6>2.3.6.5.12: Exit</h6>

|
|
|
By pushing the "Close" button the process output window is closed.
|
|
|
|
<h5>2.3.6.6: Save commands</h5>
|
|
|
|
This will save the commands immediately. The commands will be automatically saved when the application exits normally.
|
|
|
|
<h5>2.3.6.7: Delete commands or group of commands</h5>
|
|
|
|
This will delete the currently selected command or if selection is a group this will delete all commands in the group.
|
|
|
|
<h5>2.3.6.8: Activate keyboard bindings</h5>
|
|
|
|
Use this button to activate the keyboard bindings. Note that you need to have this button selected (its background should be lit in beige/orange) for the key bindings to be effective.
|
|
|
|
<h3>2.4: Graphics</h3>
|
|
|
|
When clicking on the Graphics submenu a dialog opens for setting graphics options.
|
|
|
|
|
|
|
|
<h4>2.4.1</h4>
|
|
|
|
Multisampling (MSAA) determines whether multisampling anti-aliasing is used to removed the jagged edges of lines when rendering 2D and 3D spectra.
|
|
The higher the number of samples chosen, the better quality the anti-aliasing will be, but higher values require more GPU processing and memory.
|
|
|
|
Changing this option will only take effect when spectrum windows are recreated (not just hidden then made visible again), so in some cases it
|
|
may be necessary to restart SDRangel to see the difference.
|
|
|
|
<h2>3: Help</h2>
