Step 8: Now you can start to design the user interface (.uir file) and call the

UniDAQ DLL in your project.

For example: Write Digital Input and Digital Output application, as follows:

1. Design digital I/O form.

2. Write the code as below:

<cvirte.h>

<userint.h>

"UniDAQ_DIO.h"

"UniDAQ.h"

panelHandle;

wBoardNo; wBoardIndex;

szModelName[20]="Unknow Device";

main (int argc, char *argv[])

int iCardNum =0;

WORD wTotalBoards;

if (InitCVIRTE (0, argv, 0) == 0)

return -1; /* out of memory */

if ((panelHandle = LoadPanel (0, "UniDAQ_DIO.uir", PANEL)) < 0)

return -1;

Q. How to drive a DAQ card with LabWindows/CVI ?

A: Please follow these steps:

Step 1: Install the driver.

1. Setup the UniDAQ driver. The driver is located at: CD:\NAPDOS\PCI\UniDAQ\DLL\Driver\

ftp://ftp.icpdas.com/pub/cd/iocard/pci/napdos/pci/unidaq/dll/driver/

2. For detailed information about the UniDAQ driver installation, please refer to UniDAQ DLL Software Manual contained in: CD:\NAPDOS\PCI\UniDAQ\Manual\

http://ftp.icpdas.com/pub/cd/iocard/pci/napdos/pci/unidaq/manual/

Step 2: Install the hardware on PC.

1. Power off the PC.

2. Remove all covers from the computer.

3. Carefully insert the DAQ Card into slot.

4. Replace the PC covers.

5. Power on the PC.

Step 3: Get the “.h” and “.lib” files.

You can get the “UniDAQ.h” and “UniDAQ.lib” files from the VC demo. The VC demo is located at: CD:\NAPDOS\PCI\UniDAQ\DLL\Demo\
