Issues

• areaDetector:
  • PRs:
    • Simplify build configuration
      • Let's wait for Andrew's up-to-date version

    • Convert NDPluginPva to use PVXS
• ADSupport:
  • PRs:
    • Build module with MingW (and other compilers) with Ubuntu host on our GitLab server.
• ADHamamatsuDCAM:
  • PRs:
    • Add PV for monitoring camera system alive property.
• ADMythen:
  • PRs:
    • Adding test pattern readout mode
      • This relates to other problems faced, including a timeout when using writeRead method, which would always return a single packet when the detector sent multiple ones
• ADPilatus:
  • Issues:
    • Camserver simulator
      • Jakub mentioned that these are being used to write unit tests with googletest, which can be upstreamed eventually
      • Augusto mentioned an idea of having such simulators listed in a single place, e.g. https://epics-controls.org/resources-and-support/modules
• ADUVC:
  • Issues:
    • Implement digital binning and ROI selection
      • This is relevant for having a way to query the metadata regardless of having an array forwarded to the plugin, and without querying the plugin chain structure
    • Make color mode, data type, max size, and framerate read only
    • Use readEnum to populate possible acquisition modes
• ADViewers:
  • PRs:
    • Image j macros
• ADVimba:
  • Issues:
    • Vimba X SDK Support?

  • PRs:
    • In the pvaDriverConfig function, make it possible to use a non-defaul…
• Stale Items:
  • Stale Issues:
    • Create mixer plugin
    • NDFileNexus problem
    • Add flag to prevent overwriting files in NDPluginFile
    • Move more functionality into the ADDriver base class
      • It is still desired
      • This relates to the driver's unit testing, as it makes harder to test when almost everything is implemented in writeInt32() directly
  • Stale PRs:
    • Build ADURL with ci-scripts on Ubuntu using out GitLab server.
    • WIP: Multitrack and Improvements
    • Add setlocal, update PATH with LIGHTFIELD_ROOT
    • Updates/fixes to the driver, works at NSLS2
    • Add specialization for std::hash for PicamParameter to build on older…
    • Remove obsolete shamrockDummy.cpp to avoid confusion
    • Re-ordered includes in the main configure/RELEASE

Other subjects

• Marco mentioned he is interested in adding CI and formatting rules to the ADHamamatsuDCAM repository. He'll be checking ci-scripts and clang-format rules for this.
