3.4 Programming

3.4.1 Introduction

We supply examples for the following programming languages:

C and C++

Delphi

Excel

LabVIEW

Visual Basic

HP-Vee

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_tc08tes.c

usb_tc08tes.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_tc08tes.rch

usbtc08.h

usb_tc0832.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.
