OME-PCI-180x Software Manual

1. INTRODUCTION

The PCI-180x toolkit is a collection of DLLs for Windows 95/NT/2000/XP applications.
The DLLs are 32 bit and can be called by Visual C/C++, BC++, Visual BASIC, Delphi, and
LabVIEW.

These DLLs can perform a variety of data acquisition operations such as:

z Get software version

z Initialize data acquisition hardware

z Digital Input/Output

z A/D conversion

z D/A conversion

Page 5

OME-PCI-180x Software Manual

1.1 SOFTWARE INSTALLATION

Insert the CD ROM included with your OME-PCI-180x board and the following installation screen

should auto start.

Follow the instructions on the screen to complete the software installation. The software is designed

to support the entire OME family of data acquisition hardware, so during the installation, you will be

asked to specify your particular hardware (OME-PCI-180x board in this case). During the

installation process, you will also be prompted to enter the operating system you will be using.

After installation the following folders will be created on your computer.

Page 6

OME-PCI-180x Software Manual

Demo Folder
Contains all demonstration programs including the source code. Examples are provided for Visual
C++, Borland C++, Visual Basic and Delphi.
Please note: The VC++ demos are developed with VC++ 4.0. After setting up the environment, use
the NMAKE.EXE to compiling and linking the demo code. For example,
C:\P1602\DEMO\VC\nmake /f demo1.mak

Driver Folder

Contains software drivers, include files and definition files for the programming languages.

Manual Folder

Contains hardware user manuals, software user manuals and technical notes.

Diag Folder

Contains card diagnostic programs

Inf Folder

Contains tech notes and .INF file for the plug and play installation (only available for operating
systems that support plug and play).

Page 7

OME-PCI-180x Software Manual

1.2 PLUG & PLAY

Then the p180X.inf provides all information needed to complete the Plug & Play
installation. After the installation, the Windows will reserve the resources and
populate the registry. The Plug & Play information is shown in Figure 1. Figure 2 shows
the resources that are reserved. If the user executes “c:\WINNT\regedit.exe”, the
registration information of the PCI-180XH/L will be located under “My
Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\P180x” as in
Figure 3. Figure 4 shows the registration items in detail.

1.3 Using With Visual C++

All demo programs were created with Visual C++5.and tested under Windows 95/NT.
Key issues are given below:

1. Make sure the PATH includes the Visual C++ compiler

2. Execute the \MSDEV\BIN\VCVARS32.BAT to setup the environment. The
VCVARS32.BAT is provided by Visual C++.

3. The source program must include “P180X.H”

4. Copy the P180X.LIB, import library, to the same directory as the source program.

5. Copy the P180X.DLL, to the same directory as the source program

6. Edit the source program (refer to Demo\VC5\DEMO1.C)

7. Edit the NMAKE file (refer to Demo\VC5\DEMO1.MAK)

8. NMAKE /f DEMO1.MAK

9. Execute DEMO1.EXE

NOTE: The P180X.lib is used while linking and the P180X.DLL is used at run time.

Page 11

OME-PCI-180x Software Manual

1.4 Using With MFC

Using the PCI-180x toolkit with MFC is similar as using it with Visual C++. Key issues

are given below:

1. Use MFC wizard to create the source code

2. The source program must include “P180X.H”

3. Copy the P180X.LIB, import library, to the same directory as the source program

4. Copy the P180X.DLL, to the same directory as the source program

5. Select Build/Settings/Link and key “P180X.lib” in the object/library modules

field

NOTE: The P180X.lib is used while linking and the P180X.DLL is used in run time.

Page 12

OME-PCI-180x Software Manual

1.5 Using With BC++

The DLL was created in Visual C++ 5.0. The P180X.H and P180X.lib are also
designed for use with Visual C/C++. BC++ can not use these two files. The following
modifications are necessary.

#include <conio.h>
#include <windows.h>
HINSTANCE hDLLLib;

// Step 1 : declare a function pointer

float CALLBACK (*FloatSub2)(float fA, float fB);
main()
{

// Step 2 : load dll

hDllLib=LoadLibrary("P180X.dll");
if (hDLLLib)
{

// Step 3 : get the function address

FloatSub2=(FARPROC)GetProcAddress(hDLLLib,"P180X_FloatSub2");
if (FloatSub2)
{

// Step 4 : call function

printf("1.2-3.4=%f",FloatSub2(1.2,3.4);
}
else printf("get P180X_FloatSub2 function address error");

// Step 5 : free library

FreeLibrary(hDLLib);
}
else printf("load P180X.dll error");
getch();
}

This usage can be divided into

and P180X.DLL, the user can use BC++ to call DLL.

5 steps listing above. Using this modification

1.8 Calling the DLL from LabVIEW

LabVIEW is a graphical programming language developed by National Instruments.

P180X.Dll Æ DLL

DEMO1.VI Æ Demo VI

MFUN1.VI Æ Driver VI

NOTE :

1. Tested under Windows 95/NT and LabVIEW 4.0

2. The demo1.VI will call MFUN1.VI to perform M_Functions. The M_Functions can send

out an arbitrary waveform to the D/A output port and perform the A/D operation at the
same time. If D/A channel_0 is connected to A/D channel_0, M_Functions can
measure the D/A output back. The output response is shown in Fig 8 and the
connection diagram of demo1.VI is given in Fig. 9.
