  • Method Details

    • getSystemType

      public String getSystemType()
      Specified by:
      getSystemType in class DaqSystem
      Returns:
      The 'type' of data source for display in the Data Source dialog

      Calling functions should be able to handle 'null'

    • getSystemName

      public String getSystemName()
      Specified by:
      getSystemName in class DaqSystem
      Returns:
      A string describing the data source, e.g. the sound card name, file name, udp port, etc.

    • 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

    • dialogSetParams

      public void dialogSetParams()
      Description copied from class: DaqSystem
      Called by AcquisitionDialog.SetParams so that the dialog componenet can update it's fields
      Specified by:
      dialogSetParams in class DaqSystem

    • dialogGetParams

      public boolean dialogGetParams()
      Description copied from class: DaqSystem
      Called by AcquisitionDialog.GetParams so that parameters can be extracted from the dialog component. The DaqSystem should also implement PamSettings and handle storage of parameters between runs.
      Specified by:
      dialogGetParams in class DaqSystem
      Returns:
      true if the parameters and selections are OK. If false is returned the Acquisition dialog will not respond to its Ok button.

    • getMaxSampleRate

      public int getMaxSampleRate()
      Specified by:
      getMaxSampleRate in class DaqSystem
      Returns:
      the maximum sample rate supporrted by the selected device, or PARAMETER_UNKNOWN

    • getMaxChannels

      public int getMaxChannels()
      Specified by:
      getMaxChannels in class DaqSystem
      Returns:
      the maximum number of channels supporrted by the selected device, or PARAMETER_UNKNOWN

    • getPeak2PeakVoltage

      public double getPeak2PeakVoltage(int swChannel)
      Specified by:
      getPeak2PeakVoltage in class DaqSystem
      Returns:
      peak to peak voltage for the device or PARAMETER_UNKNOWN

    • 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.
      Returns:
      true if OK, false otherwise.

    • startSystem

      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.
      Returns:
      true if OK, false otherwise

    • stopSystem

      public void stopSystem(AcquisitionControl daqControl)
      Description copied from class: DaqSystem
      Stop the DaqSystem.
      Specified by:
      stopSystem in class DaqSystem

    • isRealTime

      public boolean isRealTime()
      Specified by:
      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.

    • canPlayBack

      public boolean canPlayBack(float sampleRate)
      Specified by:
      canPlayBack in class DaqSystem
      Returns:
      true if the system can also play back sound - likely to be true for sound cards and ASIO, and some NI cards, false for wav files. Simulator ?

    • getDataUnitSamples

      public int getDataUnitSamples()
      Specified by:
      getDataUnitSamples in class DaqSystem
      Returns:
      the number of samples expected in each data unit.

    • daqHasEnded

      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

    • getDeviceName

      public String getDeviceName()
      Description copied from class: DaqSystem
      Gets a name for the acquisition device (may just be a number but need to generalise).
      Specified by:
      getDeviceName in class DaqSystem
