Lecroy Xi series vi's

Question

I used to have a project style "driver" for the Lecroy Xi series, but now I can not find it...
I went to the Lecroy site and all they have for download now is an IVI driver
I do not understand how to use the IVI driver, from the looks of the examples it is something you would use in C not LabView....
Anyway does anyone have a copy of the old project style Lecroy drivers that had the vi's in it?

Answer 1

I guess I do not understand how to use IVI drivers. I went to the help file that comes with it and this is the example they gave.
This section provides step-by-step instructions for building a simple LabVIEW application with the LeCroyScope IVI-COM driver.
Accessing the LeCroyScope Driver from the Class Browser
The first step in building a LabVIEW application using an IVI-COM driver is to access the Class Browser and direct it to load the LeCroyScope IVI-COM driver. From LabVIEW's perspective, the LeCroyScope driver is simply a COM (aka "ActiveX") component. As such, it can be loaded via the ActiveX feature of the Class Browser.
To load the LeCroyScope into the Class Browser
From the View menu, choose Class Browser. The Class Browser window appears.
From the Object Library combo box at the top, choose ActiveX and then Select Type Libraries... The system will likely pause for several seconds as LabVIEW scans your system for all installed COM components.
From the Select Type Libraries dialog box that appears, check the checkbox labeled "IVI LeCroyScope 3.2 Type Library Version 3.2" and click OK.
From the Class combo box, select LeCroyScopeLib.ILeCroyScope.
The Properties and Methods window now displays the hierarchy of methods and properties available in the LeCroyScope driver. The items with small blue dots are interface reference properties and allow you to navigate to sub-interfaces on the driver. Double-click on one of these, such as the System interface and the Properties and Methods window is updated to display the methods and properties of the sub-interface. To navigate back to the root of the hierarchy, click on the System hyperlink in the Selected property or method textbox near the bottom.
Initializing the Driver
The two main LabVIEW primitives required to access IVI-COM driver methods and properties are the Invoke Node (for methods) and the Property Node (for properties). Conveniently, the Class Browser automatically creates and configures these nodes for you.
Before any Invoke Node or Property Node can execute on the IVI-COM driver, it must be instantiated. This is accomplished using the Automation Open VI from the ActiveX palette. The following procedure explains how to instantiate and initialize the driver.
To instantiate and initialize the the LeCroyScope driver
From the Class Browser, choose the Initialize node from the hierarchy displayed in the Properties and Methods window. Drag-n-drop the node onto the block diagram.
The Automation Open VI is used to instantiate the IVI-COM driver before executing the Initialize function. Right-click on the Initialize Invoke Node just at the top left corner at the reference input, and select ActiveX Palette and then Automation Open. This creates the Automation Open VI. Make sure the Automation Refnum output of the Automation Open VI is wired to the reference input of the Initialize Invoke Node. Also, make sure the error clusters of the two VIs are wired together.
The Automation Open VI requires an input control. Right-click on the Automation Refnum input of the Automation Open VI and choose Select ActiveX Class and then choose Browse.
From the Type Library combo box at the top, choose "LeCroyScope Version 3.2". Expand the LeCroyScope node and choose ILeCroyScope (the first interface under the expanded node). Click OK.
LabVIEW creates an Automation Refnum input control and wires it to the Automation Open VI. Make sure the error clusters of the two VIs are wired together.
At this point, the VI will not compile since some of the required inputs of the Initialize Invoke Node have not be supplied. Right-click on the ResourceName input of the Initialize Invoke Node and choose Create and then Constant. LabVIEW places a constant string on the diagram and wires it to the ResourceName input. In the string constant created, enter the appropriate VISA resource descriptor for connecting to the instrument.
Right-click on the IdQuery input of the Initialize Invoke Node, choose Create and then Constant. LabVIEW creates a constant boolean wired to the IdQuery input. Repeat this process with the Reset input.
At this point, the application is executable. LabVIEW will instantiate the LeCroyScope IVI-COM driver and call the Initialize function. However, we must properly close the IVI-COM driver. We must also have the ability to read and write driver properties. These final tasks are convered in the next sections.
