PicoLog 1000 Series Programmer's Guide 25

3.4

Example programs

3.4.1

Introduction

We supply examples for the following programming languages:

C and C++

Delphi

Excel

LabVIEW

Visual Basic

Agilent VEE

3.4.2

C and C++

Use the following files:

pl1000.lib

pl1000api.h

pl1000bc.lib

pl1000con.c

C++

C++ programs can access all versions of the driver. If pl1000api.h is included in a

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

decoration, and enables C++ routines to make calls to the driver routines using C

headers.

3.4.3

Delphi

pl1000.dpr is a complete program that opens the driver and reads values from

Channel 1.

The file pl1000.inc contains a set of procedure prototypes that you can include in

your own programs.

You will also require the following files:

pl1000.vh

pl1000fm.dfm

pl1000.pas

3.4.4

Excel

The easiest way to transfer data to Excel is to use PicoLog. However, you can also

write an Excel macro which calls pl1000.dll to read in a set of data values. The

Excel macro language is similar to Visual Basic.

The example pl1000.xls reads in 20 values from Channels 1 and 2, one per second,

and assigns them to cells A1..B20.

Use Excel Version 7 or higher.

Note that it is usually necessary to copy the DLL file to the \windows\system

directory.
