VVIO: a library for I/O

VincenzoV.net Input Output project is a functions library for simple use of electronic circuits you can find on http://www.vincenzov.net. You can use it to build your-own high level code or as sample code to write your-own low-level code for your home-build hardware. There are also generic I/O functions for parallel port.

Also not being open source software, the non commercial use is free under wide conditions and, beside the binary code, is distributed the source code. Read the license.

The library code has several parts:

basicVVIO : the true library that supply interface to the hardware. It is independent from the operating system and available only as source code. It is written in C language
VVIO.dll : a library that allows the management of the hardware in all Windows environment using any languages. It uses basicVVIO functions
VVIO.sys : the device driver for Windows NT, 2000, Xp. It uses basicVVIO functions and should be used by VVIO.dll

This table will show some samples code using VVIO libraries. You can download it from pages describing hardware design and you will find source code and binary programs.

	TurboC (DOS)	LW/CVI (Windows)	VisualBasic (Windows)	gcc (Linux)
Mini-datalogger
Micro-step driver
Step driver

If you wish to publish on my web site your-own programs using VVIO library, you can send it (source and binary) to me. Obviously you will be exclusive copyright holder.

All the files in VVIO project are contained in VVIO.tgz compressed file.

license	The use license
basicVVxx.x	Source files
DLL\	The DLL for windows
SYS\	The device driver for windows NT / 2000 / XP

These circuits are supported from VVIO project:

Mini-datalogger: a 8 channel / 12 bit ADC connect to parallel port
Micro-step driver: driving up to six bipolar stepper motor with a single parallel port
Step driver: driving up to twelve unipolar stepper motor or up to 48 DC load
