DriverLINX interface

For maximum portability and versatility, it is recommended that the DriverLINX

interface be used. The DriverLINX interface has the following advantages:

•

Hardware independence

— DriverLINX supports ISA, PCMCIA, and PCI

digital I/O boards with a common interface as well as digital ports on analog
I/O and counter/timer boards.

•

Operating system independence

— DriverLINX supports Windows 95/98

and Windows NT with a common interface.

•

Shared hardware access

— DriverLINX allows multiple processes or

threads to cooperatively share hardware resources.

•

Multi-tasking, multi-threading support

— DriverLINX provides the syn-

chronization and coordination for multi-tasking, multi-threading applications
to safely access shared hardware resources.

•

Portability

— DriverLINX supports older and newer hardware with a

common interface for 16- and 32-bit applications on Windows 95/98 and
Windows NT.

•

Versatility

— DriverLINX supports a wide variety of programming styles

and languages including C/C++, Visual Basic, Delphi, and LabVIEW.

•

Background I/O

— DriverLINX supports background I/O using interrupts or

other techniques so your application can overlap processing and data
acquisition.

•

Full hardware support

— DriverLINX supports all the hardware’s features.

The DriverLINX interface has a few disadvantages compared to the alternative

interfaces:

•

Software modifications

— Existing applications will require rewriting to use

DriverLINX.

•

No direct hardware access

— Before Windows NT, Microsoft discouraged,

but nevertheless allowed, direct application program access to hardware.

•

Speed of single-value I/O

— Applications, especially those ported from

DOS, that depend on rapid software polling of I/O ports will notice that the
operating system time cost for multi-tasking, multithreading synchronization
is higher than direct hardware access.

While writing your application to use a multi-product (portable application pro-

gramming interface is the best long-term solution) you should consider the alternative
API only for special purpose or short-term needs.
