Parallel Port Complete book is for programmers, hardware designers
and anyone who uses the PC's parallel port to communicate
with printers and other peripheral devices. The tips, tools
and examples in this complete reference will save time, spark
new ideas for your own projects, and help you make maximum
use of all the port's abilities, including the new high-speed,
bi-directional modes.
Parallel Port Complete book serves as a practical,
hands-on guide to all aspects of the parallel port. Parallel
Port Complete book covers hardware and software, including
how to design external circuits that connect to the port,
as well as how to write programs to control and monitor the
port, including both the original and improved port designs.
Parallel Port Complete book covers all the port's modes, including
the original Centronics-compatible interface and the later
Byte, EPP and ECP modes. In addition to explaining what each
mode can do and how it accomplishes it, the author Jan Axelson
has shown how to select and use each mode on a PC.
Parallel Port Complete book is designed to serve readers
with a variety of backgrounds and interests:
-
Programmers will find code examples
that show how to use the port in all its modes. If you
program in Visual Basic, you can use the routines directly
in your programs.
-
For Hardware Designers, there
are details about the port circuits and how to interface
them to the world outside the PC. The author Jan Axelson
covers the port's original design and the many variations
and improvements that have evolved. Examples show how
to design circuits for reliable data transfers.
-
System Troubleshooters can use
the programming techniques and examples for finding and
testing ports on a system.
-
Experimenters will find dozens
of circuits and code examples, along with explainations
and tips for modifying the examples for a particular application.
-
Teachers and students have
found the parallel port to be a handy tool for experiments
with electronics and computer control. Many of the examples
in this book are suitable as school projects.
-
Last but not least, it explains to Users,
or anyone who uses a computer with printers or other devices
that connect to the parallel ports, how to add a port,
and gives information on cables, port extender and switch
boxes.
To demonstrate the different modes, the author
Jan Axelson has included Visual-Basic code and simple hardware
circuits that emulate peripherals. Because Windows had limited
built-in support for the advanced modes, the examples use
direct port accesses from applications, using a DLL provided
on the disk, which comes along with the book.
Parallel Port Complete book also has a variety
of simple applications, such as an interface to an analog-to-digital
converter, control of a synchronous serial link, and various
ways to use the port to switch power to a load. The examples
include schematics, explainations, & program code.
The author Jan Axelson, explains when to
use a low-level device driver to access the port (for hardware
interrupts, for example) and the options for drivers, which
include buying a control that accesses a generic driver and
writing a custom driver.
