Programming
It is very easy to program from any language that supports writing to and reading from I/O
ports. An 8255 chip contains the 24 lines of digital I/O and an 8254 chip contains the 3 16-
bit counters. Optional software drivers, called UNIV-DRVR, are available for
programming in both DOS, Windows 3.1 and Windows 95. DOS support includes
QuickBasic 4.5, Visual Basic, Turbo C, Visual C++, Microsoft C and Quick C. Windows
support includes Microsoft C, Visual C++, Visual Basic, Borland C, and C++. Labview
drivers are also available. (requires UNIV-DRVR)
I/O Connector
The connector carries 24 digital I/O lines plus the counter inputs and outputs. The 8255
digital I/O chip has 24 I/O lines. The chip is configured as three ports. Two ports, A and B,
are 8-bits wide. Port C may be an 8-bit port or two 4-bit ports. Individual ports may be
configured as input or output, and are written to or read from as a unit. Counter inputs,
gates and outputs may be controlled or chained at the connector, or inboard on a counter
chaining jumper.
