    • getDaqSpecificDialogComponent

      public JComponent getDaqSpecificDialogComponent(AcquisitionDialog acquisitionDialog)
      Description copied from class: DaqSystem
      The AcquisitionDialog has been designed to that each data source type can plug in it's own panel of device specific controls. These could be things like a file name, gain settings, channel lists, whatever is available for the specific device

      The AcquisitionDialog will handle placing this component on the dialog when a particular DaqSystem is selected. The component will be placed between a drop down list of available DaqSystem's and a section of the dialog showing the sample rate and number of channels.

      Specified by:
      getDaqSpecificDialogComponent in class DaqSystem
      Parameters:
      acquisitionDialog - the AcquisitionDialog this component will be added to
      Returns:
      dialog component specific to this DAQ device

      isRealTime in class DaqSystem
      Returns:
      true for real time systems (e.g. sound cards, NI cards, wav files which are being played back over speakers. false for reading files which are to be processed as fast as possible with no playback.

    • prepareSystem

      public boolean prepareSystem(AcquisitionControl daqControl)
      Description copied from class: DaqSystem
      Prepare the DaqSystem.

      Usually this is the time for opening files, preparing data buffers, etc.

      Specified by:
      prepareSystem in class DaqSystem
      Parameters:
      daqControl - AcquisitionControl unit.

      public boolean startSystem(AcquisitionControl daqControl)
      Description copied from class: DaqSystem
      Start the DaqSystem. This is called immediately after PrepareSystem

      Most things should be ready from the call to PrepareSystem. In StartSystem you will generally need to start a thread which will read in the data and place PamDataUnits in a buffer from where they are read by the main thred and passed on to other Pam modules for processing (see SoundCardSystem for an example)

      Specified by:
      startSystem in class DaqSystem
      Parameters:
      daqControl - AcquisitionControl unit.

      public void daqHasEnded()
      Description copied from class: DaqSystem
      Called after DAQ has stopped - for whatever reason. Nost DAQ systems will not need to do anything here, but they could potentially clean up memory The motivation for putting this here now is for the folder analysis system so that it can start analysing the next file.
      Specified by:
      daqHasEnded in class DaqSystem

    • getSettingsReference

      public Serializable getSettingsReference()

      Specified by:
      restoreSettings in interface PamSettings
      Returns:
      true if successful The object performs final checks (if needed) and then casts the settings data pamcontrolledunitSettings.settings into the correct type and uses as required

    • getPlaybackSystem

      public PlaybackSystem getPlaybackSystem(PlaybackControl playbackControl, DaqSystem daqSystem)
      Description copied from class: DaqSystem
      Gets a playback system for playing sound back out through headphones / speakers, etc.

      Generally, anything acquiring data in real time should play the sound back through itself so that clocks are correctly synchronised. i.e. A sound card input will go to the same sound card output, etc. At a later date, we may try to support output through different devices at different speeds - but this will be problematic !

      If data are being read from a file, then playback is through a sound card which sits in a stand alone implementation of PlaybackSystem

      Overrides:
      getPlaybackSystem in class DaqSystem
      Returns:
      null if no playback available or a PlaybackSystem object.
