NIDAQProcess

public NIDAQProcess(AcquisitionControl daqControl)

Method Details

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.

getDataUnitSamples

public int getDataUnitSamples()

Specified by:

getDataUnitSamples in class DaqSystem

Returns:

the number of samples expected in each data unit.

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

getDaqSpecificChannelListPanel

public ChannelListPanel getDaqSpecificChannelListPanel(AcquisitionDialog acquisitionDialog)

Description copied from class: DaqSystem

Get a channel list panel (invented for NI cards which have many more options)

Overrides:

getDaqSpecificChannelListPanel in class DaqSystem

Parameters:

acquisitionDialog - reference to main acquisition dialog

Returns:

ChannelListPanel component.

getDaqSpecificDialogComponent

public JPanel 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

setVP2P

public void setVP2P(double vp2p)

getNiParameters

public NIDaqParams getNiParameters()

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

getMasterDevice

public int getMasterDevice()

Get the index of the master device.

Returns:

getDeviceInfo

public NIDeviceInfo getDeviceInfo(int iDevice)

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.

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.

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 ?

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.

See Also:

• PlaybackSystem
• FilePlayback

getMaxChannels

public int getMaxChannels()

Specified by:

getMaxChannels in class DaqSystem

Returns:

the maximum number of channels supporrted by the selected device, or PARAMETER_UNKNOWN

getMaxSampleRate

public int getMaxSampleRate()

Specified by:

getMaxSampleRate in class DaqSystem

Returns:

the maximum sample rate supporrted by the selected device, or PARAMETER_UNKNOWN

readSampleRate

public double readSampleRate()

Pass through for easy access from channellistpanel

Returns:

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.

getChannels

public int getChannels()

isEnabledMultiBoardOps

public boolean isEnabledMultiBoardOps()

getSampleRate

public int getSampleRate()

getPeak2PeakVoltage

public double getPeak2PeakVoltage(int swChannel)

public String getUnitType()

Specified by:

getUnitType in interface PamSettings

Returns:

A Name specific to the type, e.g. Click detector

restoreSettings

public boolean restoreSettings(PamControlledUnitSettings pamControlledUnitSettings)

enableMasterDevice

public void enableMasterDevice()

setMasterDevice

public void setMasterDevice(int iDevice)

fullBuffer

public void fullBuffer(int iChan,
 double[] data)

Get's called back from the C side. The data are still in a shared buffer at this point, so copy it out into a new array.

We also need to swap threads at this point, so add the new data to a list that some other process will be emptying on a timer.

Parameters:

iChan - channel number

data - data array.

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

getDeviceList

public int[] getDeviceList()
