LabPowerQt is an application to control laboratory power supplies and to record and visualize the data.
The software is written using the Qt Framework and therefor works on Linux, Windows and OS X. Although it works cross platform the main target platforms for this project are Linux and osx.
The application is in an early stage of development make sure to read the known issues section.

- Cross plattform written in Qt
- Support for polling frequencies higher than 1Hz
- Full support of the Korad SCPI Interface
- Device Wizard for simple device setup
- Visualize Data in a fully customizeable Plot with image export functionality
- Store Data in a Database
- Manage recorded sessions
- Export Data to csv files
The following dependencies are required to run this software:
- cmake >= 2.8.12 (On Windows you need at least version 3.3)
- One of these Compilers:
- gcc >= 4.9
- clang >= 3.4
- MSVC >= 14 (Visual Studio 2015)
- MinGW
- Qt >= 5.2 (Qt5Widgets, Qt5Gui, Qt5Core, Qt5SerialPort, Qt5Sql, Qt5PrintSupport, Qt5Quick)
- ealogger >= 0.8 (Included as external project)
In order to install LabPowerQt you can obtain the source code from github or use one of the precompiled packages.
If you want to compile LabPowerQt yourself you will find these cmake options useful:
- EALOGGER_EXTERNAL - Settings this to on will automatically download and build ealogger. (Default ON)
Compiling LabPowerQt on Linux and OS X using unix make files.
# download the source code and change to the directory
# create a build directory
mkdir build
cd build
# run cmake to create makefiles. Use -DCMAKE_PREFIX_PATH if cmake doesn't find
# your installation of Qt5
cmake -DCMAKE_BUILD_TYPE=Release ../
# now compile the source code and create the application. You can speed up
# compilation with make's j option.
make
# install the application
sudo make install
There are packages for the following Linux distributions:
You can compile LabPowerQt on Windows using cmake's Visual Studio Generator.
# create build directory inside labpowerqt source directory
mkdir build
cd build
# Assuming you are using Visual Studio 2015 on a 64bit windows installation and
# Qt 5.6 installed to C:\\Qt
# Please change these options so they suit your build evironment.
cmake -G"Visual Studio 14 2015 Win64" -DCMAKE_PREFIX_PATH="C:\\Qt\\5.6\\msvc2015_64" ../
You may now open the solution file with visual studio and compile the application.
Other possibilities are cmake's NMake Generator or mingw.
I am providing an InnoSetup based installer for x86 and amd64 containing all dependencies. It is downloadable from github.com
Currently we only support Devices using the Korad SCPI Protocol
The Application is easy to use and most things should be self explanatory. Many controls offer tooltips about what they do.
To control the device connected to your computer you have to use the Control Area in the main window. It consists of green and orange elements and serves for two purposes at the same time. The current state of the device is displayed there and you can use the orange elements to control the device (by double-clicking them).
The data of the device is stored in memory. You can also persist the data in a SQLite database by turning on a Recording.
The data is not displayed in the control but can also be visualized in a Plot on the right side of the main window. Have a look at the buttons above the Plot to discover all the possibilities you have (e.g. change graph color or line style, export plot as image, discard data and many more).
The settings dialog is important as you have to use the build in device wizard to add a device. Other things can be set there as well.

Brief overview over the development process.
The github repository of labpowerqt has several different branches.
- master : Main development branch. Everything in here is guaranteed to compile and is tested. This is the place for new features and bugfixes. Pull requests welcome.
- dev : Test branch and wild west area. May not compile.
- release-x.x : Branch for a release. Only bugfixes are allowed here. Pull requests welcome.
- gh-pages : Special branch for static HTML content and images hosted by github.io.
The source code is formatted with clang-format using the following configuration
Language : Cpp,
BasedOnStyle : LLVM,
AccessModifierOffset : -4,
AllowShortIfStatementsOnASingleLine : false,
AlwaysBreakTemplateDeclarations : true,
ColumnLimit : 81,
IndentCaseLabels : false,
Standard : Cpp11,
IndentWidth : 4,
TabWidth : 4,
BreakBeforeBraces : Linux,
CommentPragmas : '(^ IWYU pragma:)|(^.*\[.*\]\(.*\).*$)|(^.*@brief|@param|@return|@throw.*$)|(/\*\*<.*\*/)'
I decided to use semantic versioning
Travis CI is used as continuous integration service. The labpowerqt github repository is linked to Travis CI. You can see the build history for the master branch and all release branches on the travis project page.
Have a look in the todo folder. I am using the todo.txt format for my todo lists.
Please use the github bugtracker to submit bugs or feature requests
-
The application does store the visibility for each graph (current, wattage ...) and this state is reapplied from the settings file whenever you start labpowerqt. Currently this is not working correctly with QCustomPlot and there is nothing I can do about it as I believe it is because of a bug in their code.
-
Polling frequencies higher than 1Hz seem to work unreliable on OSX and Windows. I have no idea if this is a problem with QtSerialport or the underlying driver implementation or system layer.
