3.1

The C example is a console mode program that demonstrates the facilities of the

driver.

To compile the program, create a new project containing the following files from the

USB PT-104 SDK:

USBPT104con.c

and:

UsbPt104bc.lib (Borland 32-bit applications) or

UsbPt104.lib (Microsoft Visual C 32-bit applications)

The following file must be in the compilation directory:

UsbPt104Api.h

and the following file must be in the same directory as the executable:

USBPT104.dll

3.2

Excel

The easiest way to transfer data into Excel is to use PicoLog.

If, however, you need to do something that is not possible using PicoLog, you can

write an Excel macro that calls UsbPt104.dll to read in a set of data values. The

Excel Macro language is similar to Visual Basic.

The example USBPT104.xls reads values from all four channels every second and

assigns them to cells in the spreadsheet.

3.3

LabVIEW

The routines described here were created using LabVIEW 8.2 on Windows XP.

To use these routines, copy usbpt104.dll to your LabVIEW user.lib directory.

USBPT104.vi is a fully functional example LabVIEW application. It demonstrates how

to connect to the device using both USB and Ethernet. It also demonstrates reading all

possible measurement types from the four channels.
