Data Acquisition Toolbox 2.2 Release Notes

New Features

This section summarizes the new features and enhancements introduced in the Data Acquisition Toolbox 2.2.

If you are upgrading from a release earlier than Release 12.1, then you should see New Features in the Data Acquisition Toolbox 2.1 Release Notes.

Keithley Adaptor

The Data Acquisition Toolbox now supports Keithley hardware that uses the DriverLINX driver. You can create device objects associated with the analog input, analog output, and digital I/O subsystems for these boards. A complete list of supported devices is provided by the MathWorks Web site at http://www.mathworks.com/products/daq/hardware.shtml.

Example: Creating a Keithley Analog Input Object

To create an analog input object associated with your Keithley hardware, you must supply the Keithley adaptor name and the hardware device ID to the analoginput creation function. Note that you configure the ID with the DriverLINX configuration panel.

```
ai = analoginput('keithley',1);
```

You can use the set function to display the properties associated with ai.

```
set(ai)
```

Software Oscilloscope

The software oscilloscope is a graphical tool that duplicates and extends the functionality of a real-world oscilloscope. Using this tool, you can access hardware channels, and display and analyze acquired data. To open the software oscilloscope, type

```
softscope
```

Parallel Port Adaptor

The toolbox provides access to your computer's parallel port through a digital I/O object. You create a digital I/O object with the digitalio function.

```
parport = digitalio('parallel','LPT1')
```

You can display port-specific information with the daqhwinfo function.

out = daqhwinfo(parport)
out = 
                AdaptorName: 'parallel'
                 DeviceName: 'PC Parallel Port Hardware'
                         ID: 'LPT1'
                       Port: [1x3 struct]
              SubsystemType: 'DigitalIO'
                 TotalLines: 17
    VendorDriverDescription: 'Win I/O'
        VendorDriverVersion: '1.3'

The parallel port device object provides access to the three available ports:

Port 0--Eight input/output lines used for data
Port 1--Five input lines used for status
Port 2--Four input/output lines used for control

The parallel port device object contains two device-specific properties-- BiDirectionalBit and PortAddress. Use the daqhelp function for a description of these properties.

daqhelp BiDirectionalBit
daqhelp PortAddress

Access Objects Using the Workspace Browser

You can configure properties and view information associated with device objects via the MATLAB Workspace browser:

Start the Data Acquisition Property Editor by double-clicking a device object variable.
Right-click a device object variable and select the Explore menu to
