Welcome to dactl’s documentation!¶
Contents:
Introduction¶
Dactl is an application for creating custom data acquisition and control systems under the GNOME desktop environment. At this time it is heavily dependent on the existence of a valid configuration, the details of which are entirely undocumented.
There is a companion library that dactl is pretty heavily reliant on and will be referenced to through the documentation, libcld. It has it’s own (incomplete) documentation which can be viewed here.
This software is still in early stages of development
Existing Features¶
- XML configurable UI classes for:
- AI channel
- AO channel
- DI channel
- DO channel
- Log file (start/stop)
- Strip chart
- UI for changing the properties of:
- libcld channel types (AI/AO/DI/DO/Math)
- libcld data series (incomplete)
- libcld channel calibrations
- libcld logs
- A page to export logged database tables as CSV files
- Framework for custom plugins. See the example plugin. <https://github.com/coanda/dactl-mcc-plugin>
Planned Features¶
- Configuration-less mode
- DBus API for adding and configuring UI
- XML configurable UI classes for:
- Recording video from OpenCV compatible cameras
- Chart for viewing recorded history of measurement data
- Data browser that connects to stored CSV and SQLite logs
- UI for changing the properties of:
- General application settings
- All dactl UI widgets
- Peas plugin loader
- Ability to tweak dactl UI widgets using Gtk properties of underlying classes
Other Things that are Present but Non-functional¶
- All plugins in src/plugins other than Velmex which is only partially complete
- A page to edit the configuration file using gtksourceview
Installation¶
Requirements¶
- Linux is the only tested OS
- GNOME 3 is the only tested DE
- Vala
Building from Source¶
The source code is hosted on GitHub.

Compiled Dependencies¶
Install Vala dependencies¶
1 2 3 4 5 6 7 | git clone https://github.com/geoffjay/modbus-vapi.git
git clone https://github.com/geoffjay/comedi-vapi.git
sudo mkdir -p /usr/local/lib/pkgconfig
sudo cp comedi-vapi/comedi.pc /usr/local/lib/pkgconfig/
ver=`vala --version | sed -e 's/.*\([0-9]\.[0-9][0-9]\).*/\1/'`
sudo cp comedi-vapi/comedi.vapi /usr/share/vala-$ver/vapi/
sudo cp modbus-vapi/libmodbus.vapi /usr/share/vala-$ver/vapi/
|
Install libcld¶
1 2 3 4 5 6 7 8 9 | git clone https://github.com/geoffjay/libcld.git
cd libcld
git checkout v0.3.1
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
./autogen.sh
make && sudo make install
cd ..
echo "/usr/local/lib" | sudo tee --append /etc/ld.so.conf
sudo ldconfig
|
Compile and Install dactl¶
Warning
Installation overwrites the configuration file at $(sysconfdir)/dactl/, if an alternate value wasn’t provided for –prefix than this is probably /usr/local/etc/dactl. It’s recommended that the existing configuration is copied over data/config/dactl.xml or backed up and dealt with separately.
1 2 3 4 5 | git clone https://github.com/coanda/dactl.git
cd dactl
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
./autogen.sh
make && sudo make install
|
Post-installation Configuration¶
The make install command given previously will overwrite the site-wide configuration, to fix the ownership settings you may need to do something along the lines:
1 2 3 | chown -R `whoami`.$(id -gn `whoami`) /usr/local/etc/dactl
chmod -R g+w /usr/local/etc/dactl
chmod +x /usr/local/share/applications/dactl.desktop
|
Optional but Useful¶
Currently the only drivers tested for data acquisition hardware are comedi. You might be able to do something in dactl without comedi, but probably not. Some distributions (Ubuntu?) have support for comedi built into the kernel provided, but not Fedora. The instructions that we use for compiling comedi using dkms are
1 2 3 4 5 6 7 8 9 10 | su -
dnf install -y automake autoconf libtool git dkms kernel-devel kernel-headers
git clone git://comedi.org/git/comedi/comedi.git
cp -R comedi/ /usr/src/comedi-0.7.76+20120626git-1.nodist
cd /usr/src/
dkms add -m comedi -v 0.7.76+20120626git-1.nodist
cd comedi-0.7.76+20120626git-1.nodist && ./autogen.sh && cd ..
dkms build -m comedi -v 0.7.76+20120626git-1.nodist
dkms install -m comedi -v 0.7.76+20120626git-1.nodist
echo "KERNEL==\"comedi*\", MODE=\"0666\", GROUP=\"iocard\"" > /etc/udev/rules.d/95-comedi.rules
|
After these steps if you have a comedi compatible device you should be able to modprobe comedi as well as that for the device and it should show up in /dev. If not, a test device can be created by:
1 2 3 4 5 | su -
dnf install -y comedilib comedilib-devel
modprobe comedi comedi_num_legacy_minors=4
modprobe comedi_test
comedi_config /dev/comedi0 comedi_test
|
However, test devices are of limited use, they allow for instructions only on with no support [1] for commands.

Configuration¶
A collection of user interface elements are available. Configuration refers here
to the XML code that defines the individual elements. Included in the collection
are the box and page and thus a layout is created by recursively packing elements
into boxes which are in turn packed into pages.
Analog Input Control¶
This control displays the current value along with statistical data.
This section shows how to add ann analog input control to a configuration file.

Box¶
This section shows how to add a box to a configuration file. A Dactl Box inherits
properties of a Gtk Box. It is simply a container for a user interface element
or another box.

Stripchart¶
This is the legacy strip chart. The settings user interface for this was in need of improvement and so it was replaced by the real time chart. It is has been retained in the library because it has some advantages over the newer chart type. Because it traces do not interpolate the data, they look much better with noisy data than the newer real time chart trace.

Polar Chart¶
The polar chart is a surface for plotting polar data. To be complete it requires
additional polar axes and a source of data. Currently, a heatmap is the only
available drawable data source that can be displayed but trace data may be
added in a future release.

Color Map¶
This element is added to the interface as a legend showing a gradient
of colors between a set minimum and maximum color value. The gradient
type is selected to interpolate colors as either RGB or HSV.

A chart with heatmap data as it appears when added to the interface.
Here the color values have been made translucent by editing the alpha value. This
allows the grid lines to show through.
