- _Logging_: opens a dialog to choose logging options. See "Logging" paragraph next for details
- _FFT_: opens a dialog to run 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. See "FFT" paragraph next for details.
- _My Position_: opens a dialog to enter your station ("My Position") coordinates in decimal degrees with north latitudes positive and east longitudes positive. This is used whenever positional data is to be displayed (APRS, DPRS, ...). For it now only works with D-Star $$CRC frames. See [DSD demod plugin](../plugins/channelrx/demoddsd/readme.md) for details on how to decode Digital Voice modes.
- _Devices_: section to deal with devices settings
- _User arguments_: opens a dialog to let the user give arguments specific to a device and its instance (sequence) in the system
- _Commands_: opens a dialog to manage commands. See "Commands" paragraph next.
- _Save all_: save all preferences
- Help:
- _Loaded Plugins_: shows details about the loaded plugins. See "Loaded plugins" paragraph below for details.
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 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.
Creates a new transmitter (sink device set). A dialog opens to select which transmitting device to use similarly to (2) but with a choice of transmitting devices.
<h3>1.4: Create new MIMO device</h3>
Creates a new MIMO device (MIMO device set). A dialog opens to select which MIMO device to use similarly to (2) but with a choice of MIMO devices.
<h3>1.5: Create a new feature</h3>
Creates a new feature. A dialog opens to select which feature to use:
Move the cursor to select a feature. Features can be organized into groups at the top level (here "Test"). When selecting a group only Edit and Delete group are available
<h4>1.6.2: Add new preset</h4>
Save the current feature set in a new preset.
<h4>1.6.3: Update selected preset</h4>
Update the selected preset with the current feature set
<h4>1.6.4: Save presets</h4>
This button is inactive. All presets are saved at program exit or with the `Preferences`/ `Save All` main window menu.
<h4>1.6.5: Edit preset</h4>
Change preset name or the preset group to which this preset belongs. If selection is a group the group name can be changed.
Arranges windowsa in the MDO area of the workspace in a way similar to the arrangement in version 6:
- Devices are stacked in numerical order top left.
- Fixed height features are stacked in order underneath devices and resized to match width of devices
- Channels are stacked in device then channel index order down the right and resized horizontally to match and then any available vertical space is shared being vertically expanding channels
- Remaining space in the middle is shared between spectrums and expanding features
<h3>1.10: Auto stack windows</h3>
Applies the stacked arrangement above automatically when elements are added.
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.
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).
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.
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.
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.
Click on this icon to duplicate the currently selected command (inactive on groups). Later you can edit the details of the copy with the edit dialog (see 5B.6.3 next)
With this dialog you can rename a group using the text box or if you select an existing group with the combo this will merge the contents of the group with the existing group
<b>Commands</b>
You can edit the details of the command with this dialog.
Clicking on this button will open a file dialog to select the executable file that will be run with this command. The file selection dialog has predefined file pattern selections:
Use this button to capture the key or key combination that will be used for the key binding. After pushing this button just type in the key or key combination.
This will run the currently selected command. If the selection is a group it will run all commands of the group starting them in the displayed order. Please note that commands are run in independent processes and therefore all launched commands in the group will run concurrently.
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.
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.
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.
The plugin entry can be expanded or collapsed using the caret on the left. When expanded it shows more information about the copyright of the author and locations on the web where the plugin can be found. In all cases this is just here.
