[avrdude-dev] using parallel port programmers with avrdude on windows 7 64 bit and other versions of 64 bit windows

[Florea Bogdan Florin]

Hello,

I couldn't find any easy way to use parallel port 
programmers with avrdude on windows 7 because there was no equivalent 
for giveio driver, so I modified avrdude to use InpOut for parallel port
 access.
I used a modified version of InpOut for 64 bit windows from 
http://www.highrez.co.uk/Downloads/InpOut32/default.htm
I
 modified ppiwin.c, rewriting "inb" and "outb" functions to use InpOut.
This
 library, InpOut seems to work both on 32 bit windows and on 64 bit 
windows.
I think it would be useful to include support for this 
library in avrdude, so that it can be used on 64 bit versions of windows
 also. I think that avrdude should try to load giveio driver first and 
if this fails then it should try to use InpOut. 
Before running 
avrdude first time, the user should run 
windows_inpout\Win32\InstallDriver.exe which seems to install 
automatically the required version of driver (32 bit or 64 bit). A dll 
file (inpout32.dll) is also required at runtime.
I have attached the 
modified version of ppiwin.c . The only file that I modified is ppiwin.c. I
 also added windows_inpout directory containing InpOut files.
