REDISTRIBUTED FREEWARE

For your convenience, the topic's ftp site also contains some of the programs listed in the
topic as freeware that can be downloaded from the Web. These programs are included here
free of charge with the understanding that “freeware” refers to software that can be down-
loaded without having to pay money for them. These

files may be distributed freely with-
out paying anything in the way of royalties or distribution fees as long as they are not
modi

fi

ed prior to distribution. Note that this also applies to you. If you intend to distribute
further the

fi

files listed as freeware, you must make sure that you hand them out in their orig-
inal form. You must also distribute things that come in multiple parts as a complete set
(e.g., many of the computer programs have extra

fi

files; you must distribute them all
together, the way you retrieved them from the ftp site). The reason is quite simple: The
hard work that went into these products should be distributed in the way that its author
intended, not the way that someone else thinks it should be.

CONTENTS OF MEDICAL_ELECTRONIC.ZIP

Software for Introduction

Folder: Redistributed Freeware

• Little Stimulus Maker v2.0 (LSM2_SFX.EXE freeware for Windows 9x) by John Kelly.

Software for Chapter 5: Signal Conditioning, Data Acquisition,
and Spectral Analysis

Folder: Universal Sensor Interface

VB5.0

• LPT8_DVM.VBP is a VisualBasic (v5.0) application project that shows how to
develop a virtual instrument to acquire analog and digital data as well as to control
the D/A and digital outputs of the Universal Sensor Interface. INPOUT32.DLL is
used to allow input and output operations to be performed on the printer port. If 16-
bit operation is required, modify the programs to make use of the 16-bit

file.
• LPT8_LOGGER.VBP is basically the same as LPT8_DVM.VBP, but a

CUSER2.DLL fi

fi file dialog has

been added to make it possible to log acquired data directly to disk.
• LPT8_THERM is used to read temperature in °C and °F using a thermistor.

QuickBASIC

• LPTAN8.BAS is a simple program for driving the Universal Sensor Interface A/D.
• LPTAN8.EXE is the compiled (DOS) version of this program.
• ACQUIRE8.BAS implements an eight-channel oscilloscope/four-channel logic
analyzer.
