0.6.0: detach plotting from data handling in Receiver

This release detaches the plotting to e.g. pg.ImageItems from the Receiver.handle_data method, allowing to set custom plot refresh rates per receiver. This avoids forced re-plotting on every incoming data which leads to massive CPU usage for e.g. M26 telescope planes (1152x576 pixels) using pymosa.online_monitor.
Thus CPU load can be reduced by decreasing the refresh rate per receiver on-the-fly, if needed, without dropping data.
Furthermore, a lut_from_colormap function has been added to the online_monitor.utils submodule, allowing to generate lookup tables for pg.ImageItems from matplotlib.colormaps such as 'viridis', 'plasma', etc.

0.5.2: feature release

This release brings two new features

• A plugin_online_monitor script, allowing to add paths to the online_monitor default search paths. Usage:

  plugin_online_monitor my/custom/online_monitor/plugin/path
  

  or

  cd my/custom/online_monitor/plugin/path
  plugin_online_monitor
  

• A producer sim silab_default_producer, located under the examples, has been added and is automatically available. It runs out of the box for most SiLab-type DAQ outputs and can be used in the configuration.yaml like:

  producer_sim:
      DAQ:
          kind: silab_default_producer
          data_file: path/to/my/data.h5
          backend: tcp://127.0.0.1:5500
          delay: 0.2  
  

0.5.1: PyPi maintenance release

This version fixes the installation of online_monitor via the Python Package Index.
Run

pip install online-monitor

to install the package from there

0.5.0: Maintenance release

See #18! Highlights

• Dropping Python 2 support -> Only Python >= 3.7 supported from here on
• Moving CI (Linux / Windows) to GH actions
• Drop deprecated nose, use pytest instead
• Fixing the package:
  • Remove use of deprecated use of QtGui/ Qt through pyqtgraph, use pyqt5.QtWidgets instead
  • Fix versions to match pyqtgraphs testing matrix
  • Fix DeprecationWarnings due to configparser.SafeConfigParser -> configparser.ConfigParser
  • Fix tests / coverage

0.4.2: Maintenance release

• Fixing Python 2.7 and 3 compatibility issues (changes in the dict implementation)
• Fixing installation issues when using pip and the online_monitor package is not yet available.

Serialization issues with unicode and byte arrays

Some quirks with serialization are fixed by using the json api provided by pyzmq (#15). Unit tests are added for 3 different ways to serialize data with numpy arrays.

Enhance real-time capabilities and API changes

Not backward compatible API change to fix typo: serialze -> serialize

Enhancements:

• With newer pyzmq releases it was observed that the HWM feature at the receiver side does not work anymore and the online_monitor does not stay real-time. The reason for this was not found and the documentation and forums are not helpful. Therefore a input FIFO is added to the transceiver module to be in charge of data dropping.

• Data dropping is now not determined any more by CPU utilization but by input FIFO size. Each entry in this FIFO is one received data chunk. The config option is max_buffer in the yaml file.

• stop_online_monitor terminal command that kills all instances of producers, converters and reveives. This is useful when developing and crashes are expected.

Qt5 support

Features:

• switch from Qt4 to Qt5
• small code clean up

Feature release

• Bidirectional communication can be set for the converter connected to a receiver
• The configuration file does not have to defince a producer / converter / receiver
• The demo works out of the box
• Cleanup

Packaging and installation

This release fixes the pip package installation and makes nose tests work from the command line.
