Obsolete daq Functions

Two functions with daq in their name are obsolete in Version 2.11 and are replaced with other functions. The toolbox will no longer support these obsolete functions and will display an error if you try to use them. If your code still uses these obsolete function names, you must update it to use the new function names.

Obsolete Function Name

New Function Name

daqaction

daqcallback

Three Analog Properties Hidden

The following three properties of analog input objects in the NI-DAQmx adaptor are now hidden:

  • DriveAISenseToGround

  • NumMuxBoards

  • TransferMode

These properties are used only by Traditional NI-DAQ devices. If you have code that explicitly uses these properties it will continue to work, but code that puts the object's properties in a structure will no longer find these three properties. Tab completion for these three properties will no longer work.

Compatibility Considerations

In this release of the toolbox, the three properties DriveAISenseToGround, NumMuxBoards, and TransferMode are hidden for NI-DAQmx boards. You can, however, explicitly access these properties, but changing their values will not have any effect on NI-DAQmx boards.

R2007a

New Features, Bug Fixes, Compatibility Considerations

Compatibility Considerations

The change for this toolbox release is that you will see a warning if you create a Data Acquisition Toolbox object for the 'keithley' or 'hp1432' adaptors. The warning is being introduced now, but the adaptors will continue to be supported and will be removed in a future release.

R2006b

New Features, Bug Fixes, Compatibility Considerations

Data Acquisition Toolbox Block Library

You can use these blocks to acquire analog or digital data in a Simulink model, or to output analog or digital data from the model to a hardware device. The toolbox block library contains four blocks:

  • Analog Input — Acquire data from multiple channels of an analog data acquisition device.

  • Analog Output — Output data to multiple channels of an analog data acquisition device.

  • Digital Input — Acquire the latest set of values from multiple lines of a digital data acquisition device.

  • Digital Output — Output data to multiple lines of a digital data acquisition device.

New Hardware Support

Additional data acquisition hardware support was added, as follows:

  • Support added for four additional National Instruments (NI) data acquisition devices — NI USB-6251 (USB); NI USB-6259 (USB); NI PCIe-6251 (PCI Express); and NI PCIe-6259 (PCI Express).

Corrected Spelling of InputType Value Pseudodifferential

Analog input objects have a number of acceptable values for their InputType property: NonReferencedSingleEnded, SingleEnded, Differential, and Pseudodifferential. In the initial release of the NI-DAQmx adaptor in Version 2.8 (R14SP3+), Pseudodifferential was incorrectly spelled as Psuedodifferential. The toolbox change now correctly spells this input type as Pseudodifferential.

Compatibility Considerations

This change is backward compatible; users that saved analog input objects with the InputType property set to the misspelled Psuedodifferential will be able to load the object in R2006b and later with no changes on their part. The compatibility issue is that if you save an analog input object with this InputType value in R2006b, you will not be able to share it with users of R2006a and earlier versions. Analog input objects that have their InputType set to Pseudodifferential will be unusable in R2006a and previous releases. Analog input objects that use the other InputType values are unaffected.

If you use the set function to assign the incorrectly spelled value Psuedodifferential, in Version 2.9 (R2006b), you will get a warning and it will be changed to the correct spelling. In the following release of the toolbox, you will get an error advising you to use the new spelling. The get function will always return the correctly spelled value.

R2006a

Bug Fixes

R14SP3+

New Features, Bug Fixes

NI-DAQmx Support

The Data Acquisition Toolboxtm_dataacquisitiontoolbox; software supports National Instruments hardware that uses the NI-DAQmx software interface.

The adaptor name in the Data Acquisition Toolbox software is nidaq, which can be used in all syntax requiring the adaptor name.

To display your installed hardware that can be accessed using the NI-DAQmx adaptor, type

daqhwinfo('nidaq')

daqhwinfo returns information about the hardware that is installed, and the IDs that the National Instruments Measurement & Automation Explorer has assigned to these devices. Typically, these IDs start with the letters Dev followed by a number.

The toolbox supports both Traditional NI-DAQ and NI-DAQmx. For information about choosing which driver to use, see Troubleshooting Your Hardware of the Data Acquisition Toolbox User's Guide.

Upgrading from an Earlier Release

This section details the issues to be aware of when upgrading from Data Acquisition Toolbox Version 2.7 to Version 2.8.

DriveAISenseToGround Property

The DriveAISenseToGround property is ignored by National Instruments devices. For information on configuring AI referencing properties, see the reference page for the InputType property.

R14SP2

New Features, Bug Fixes

New Functions: islogging, isrunning, and issending

Three new functions are provided to query the status of data acquisition device objects.

Function

Purpose

islogging

Determine whether analog input object is logging data.

isrunning

Determine whether device object is running.

issending

Determine whether analog output object is sending data.

For further details on each function, see its reference page in the documentation. Use of these functions is recommended over directly accessing the Running, Logging, and Sending properties.

Using PFI or RTSI Channels for Triggers and Clocks

Three new properties for National Instruments cards are:

  • HwDigitalTriggerSource

  • ExternalSampleClockSource

  • ExternalScanClockSource

These properties allow you to select a PFI or RTSI channel as the source for a hardware digital trigger, external sample clock, or external scan clock. See the reference pages for these properties to read about valid property settings and when they are in effect.

peekdata Allows Type Parameter

The peekdata function now accepts a third parameter specifying data format. When the data format is specified as native, data is returned in the native format of the data acquisition device, similar to the behavior of the getdata function. For detailed information on peekdata, type

help analoginput/peekdata

Property Inspector Replaces daqpropedit

The Property Inspector replaces the Data Acquisition Toolbox Property Editor (daqpropedit) graphical user interface.

You open the Property Inspector for object obj with the inspect function.

inspect(obj)

For more information about the inspect function, type

help daqdevice/inspect

Typing daqpropedit at the command line now opens the Property Inspector.

waittilstop Function Renamed wait

The waittilstop function has been renamed wait. All functionality remains the same. waittilstop still works in Version 2.6, but may be removed from a future version of the toolbox. For more information on wait, type

help daqdevice/wait

Upgrading from an Earlier Release

This section describes the issues involved in upgrading from Data Acquisition Toolbox Version 2.5.1 (Release 14SP1), 2.5 (Release 14), or 2.2 (Release 13SP1).

Obsolete Action Properties

All object properties with Action in their name are obsolete in Version 2.6. These have been replaced by properties with the same name using Fcn instead of Action. These Fcn properties have existed in several recent versions of the Data Acquisition Toolbox software. The toolbox supported the Action properties during these transition releases, but they are no longer supported. If your code still uses these obsolete property names, you must update it to use the new property names.

Deleting a Running Object

In past releases, you could not delete a running object. Now in Version 2.6, when you attempt to delete a running object, the toolbox stops the object, issues a warning, then deletes the object.

ai.SamplesPerTrigger = Inf
start(ai);
delete(ai)
Warning: Object stopped before deleting.

Return Format of daqfind

In past versions, the daqfind function returned a 1-by-1 cell array of N-by-1 objects. Now in Version 2.6, this function returns an N-by-1 cell array of objects.

ai1 = analoginput('winsound');
ai2 = analoginput('winsound');
objs = daqfind('Type','Analog Input')
objs = 
    [1x1 analoginput]
    [1x1 analoginput]

peekdata and getdata Number of Samples

The functions peekdata and getdata no longer accept Inf as an argument for specifying the number of samples. In the past, specifying Inf for the number of samples was accepted, and returned zero samples. Now specifying Inf samples causes an error.

data = getdata(ai, Inf)
??? The number of samples requested must be less than Inf.

waittilstop Function Renamed wait

The waittilstop function has been renamed wait. All functionality remains the same. waittilstop still works in Version 2.6, but may be removed from a future version of the toolbox. For more information on wait, type

help daqdevice/wait

daqpropedit Replaced by inspect

The Data Acquisition Toolboxtm_dataacquisitiontoolbox; Property Editor (daqpropedit) graphical user interface has been replaced by the Property Inspector.

You open the Property Inspector for object obj with the inspect function.
