SAMPLES
Samples for using ACCES32.DLL are provided in this directory. Using this DLL not only
makes the hardware programming easier (MUCH easier), but also one source file can be used
for both Windows 95/98 and WindowsNT. One executable can run under both operating
systems and still have full access to the hardware registers. The DLL is used exactly like any
other DLL, so it is compatible with any language capable of using 32-bit DLLs. Consult the
manuals provided with your language's compiler for information on using DLLs in your
specific environment.
VBACCES
This directory contains sixteen-bit DLL drivers for use with VisualBASIC 3.0 and Windows 3.1
only. These drivers provide four functions, similar to the ACCES32.DLL. However, this DLL is
only compatible with 16-bit executables. Migration from 16-bit to 32-bit is simplified because of
the similarity between VBACCES and ACCES32.
PCI
This directory contains PCI-bus specific programs and information. If you are not using a PCI
card, this directory will not be installed.
SOURCE
A utility program is provided with source code you can use to determine allocated resources at
run-time from your own programs in DOS.
PCIFind.exe
A utility for DOS and Windows to determine what base addresses and IRQs are allocated to
installed PCI cards. This program runs two versions, depending on the operating system. Windows
95/98/NT displays a GUI interface, and modifies the registry. When run from DOS or
Windows3.x, a text interface is used. For information about the format of the registry key, consult
the card-specific samples provided with the hardware. In Windows NT, NTioPCI.SYS runs each
time the computer is booted, thereby refreshing the registry as PCI hardware is added or removed.
In Windows 95/98/NT PCIFind.EXE places itself in the boot-sequence of the OS to refresh the
registry on each power-up.
This program also provides some COM configuration when used with PCI COM ports.
Specifically, it will configure compatible COM cards for IRQ sharing and multiple port issues.
WIN32IRQ
This directory provides a generic interface for IRQ handling in Windows 95/98/NT. Source code
is provided for the driver, greatly simplifying the creation of custom drivers for specific needs.
Samples are provided to demonstrate the use of the generic driver. Note that the use of IRQs in
near-real-time data acquisition programs requires multi-threaded application programming
techniques and must be considered an intermediate to advanced programming topic. Delphi, C++
Builder, and Visual C++ samples are provided.
