ApplicationCore-MicroDAQ-Tools

This packages provides tools related to the ApplicationCore-MicroDAQ package that add the DAQ modules to ApplciationCore. Basically the package provides a PyQt5 based data inspector MicroDAQViewer. Features of that viewer are e.g.:

• Plot scalar and array data for single events
• Table view of scalar and array data
• Timeline of scalar and array data (time range can be given a number of events or directly by specifying the time range)
• Search for events fulfilling specific trigger requirements

Required python packages:

• PyQt5
• pyqtgraph
• h5py
• cppyy

You might need to add /usr/lib/root to PYTHONPATH and LD_LIBRARY_PATH.

Also another PyQT5 based program called UaClient is included in the package. This is an OPC-UA based live viewer. The OPCUA client is based on freeopcua and requires to install opcua-client via pip3.

If root support is enabled addition features are provided:

• libApplicationCore-MicroDAQ-Tools.so: Includes ROOT related tools. This library is used by the MicroDAQViewer when working on ROOT files
• hdf5Converter: C++ application that allows to convert HDF5 files to ROOT files, which reduces the disc usage significantly
• plot: Example showing how to use uDAQ::DataHandler class provided in libApplicationCore-MicroDAQ-Tools.so

ROOT file quick analysis

To view a property vs. entry use:

tree->Draw("Entry$:temperature")

To use the time stamp information use:

tree->Draw("timeInfo.timeStamp:temperature")

In the plot you can use SetTimeDisplay for the x-axis.

Merging ROOT files

In order to merge ROOT files use:

hadd merged.root *.root
