Programming Options

Selecting an Application Programming Interface

The PIO Series supports two different device driver interfaces to best
match your programming needs. The supported driver interfaces are

●

DriverLINX

—

An interface that is hardware and operating system

independent and supports multitasking, multi-threading applications.

●

Direct I/O

—

An interface that is operating system independent and

supports single-tasking, single-threaded access to an Intel 8255-like
function call interface.

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.

●

Multitasking, multi-threading support

—

DriverLINX provides

the synchronization and coordination for multitasking,
multi-threading applications to safely access shared hardware
resources.
