Programming

3.4.1

Introduction

We supply examples for the following programming languages:

C and C++

Delphi

Excel

LabVIEW

Visual Basic

Agilent VEE

The example programs are installed in the Examples subdirectory of your TC-08

program directory.

3.4.2

C and C++

The C example program is a generic Windows application: it does not use Borland

AppExpert or Microsoft AppWizard. To compile the program, create a new project

containing the following files:

usb_tc08.c

usb_tc08.rc

either

usbtc08bc.lib

(Borland 32-bit applications)

usbtc08.lib

(Microsoft Visual C 32-bit applications)

The following files must be in the same directory:

usb_tc08.rch

usbtc08.h

usbtc08.dll

(all 32-bit applications)

C++

C++ programs can access all versions of the driver. If usbtc08.h is included in a

C++ program, the PREF1 macro expands to extern "C": this disables name-mangling

(or name-decoration), and enables C++ routines to make calls to the driver routines

using C headers.

3.4.3

Delphi

The WIN sub-directory contains a simple program usbtc08.dpr which opens the

drivers and reads temperatures from the three channels. You will need the following

files to build a complete program.

USBTC08FM.dfm

USBTC08FM.PAS

usbtc08.inc

The file usbtc08.inc contains procedure prototypes for the driver routines. You can

include this file in your application.

This example has been tested with Delphi versions 1, 2 and 3.
