Section 4 - Programming
Programming the Matrix Using The IVI Driver, Direct I/O Driver or VISA Driver
This section provides some code fragments which show how to control the High Density Matrix using the IVI Driver, Direct
I/O Driver or the VISA Driver.
Once the drivers are installed the manual “Sys40Prg.pdf” and driver help files which fully describes these functions can
be found in the Pickering folder(s) or the Pickering entries on your Start Menu.
The card must be opened before use and closed after using the following function calls:
Direct Driver - Open with PIL_OpenCards or PIL_OpenSpeciedCard and close with PIL_CloseCards or
PIL_CloseSpeciedCards respectively.
VISA Driver - Open with pipx40_init, and close with, pipx40_close.
Setting a Matrix Crosspoint:
Using the IVI driver:
pi40iv_Connect(vi, “x1”, “y2”); //set crosspoint x1, y2 to on
pi40iv_Disconnect(vi, “x1”, “y2”); //set crosspoint x1, y2 to o
Using the Pickering Direct I/O driver:
DWORD SubUnit = 1;
PIL_ClearSub(CardNo, SubUnit); //clear all crosspoints to o state
PIL_OpCrosspoint(CardNo, SubUnit, 2, 1, 1); //set crosspoint x1, y2 to on
PIL_OpCrosspoint(CardNo, SubUnit, 2, 1, 0); //set crosspoint x1, y2 to o
Using the VISA driver:
ViUInt32 SubUnit = 1;
pipx40_clearSub(vi, SubUnit); //clear all crosspoints o state
pipx40_setCrosspointState (vi, SubUnit, 2, 1, VI_ON); //set crosspoint x1, y2 on
pipx40_setCrosspointState (vi, SubUnit, 2, 1, VI_OFF); //set crosspoint x1, y2 o

Using Pickering Drivers in LabVIEW
Most Pickering drivers include a LabVIEW wrapper to permit full operation of the Pickering product from the LabVIEW
environment. These wrappers are normally installed to the current LabVIEW folder system during installation of the
Pickering driver.
The process of controlling a Pickering product normally consists of the following steps:
1. Open a control session on the product.
2. Use functions in the library to operate the product.
3. Close the control session.
Following is a simple example of the use of the most common Pickering drivers:
