[avrdude-dev] PCI parallel ports with Windows

[René Liebscher]

Hello,

I know there were already a short dicussion about this topic in 2003 
(*Re: [*avrdude*-dev] Blank skipping, multi-byte writes, notes *on* 
parallel ports 
<http://lists.gnu.org/archive/html/avrdude-dev/2003-04/msg00077.html>*, 
http://lists.gnu.org/archive/html/avrdude-dev/2003-04/msg00078.html), 
but may be it helps to get it done now by a description how to get the 
necessary address information for the ports.

First you need to know the address of the port on your PCI card.
I used for this the SIV (System Information Viewer, 
http://www.rh-software.com/)
The necessary sequence is shown in the following images.

At the third screen you have the address you need.

After this, I tested it changing the entries from file ppiwin.c ("lpt3" 
=> "pci" and 0x3BC => 0xBC00).
(Actually I just used a hex editor on the executable, as I don't have 
the sources and compiler installed ;-)

As you can see on the image 
(http://robot.informatik.uni-leipzig.de/~liebschr/avrdude/result.PNG) 
this works perfect.

If some other people could try this procedure, and find if it works for 
them too, then it could be included in a next release of avrdude?

I have no complete patch for it, but using "strtoul" as already proposed 
would be the way to parse something like "pci_0xBC00" or similar.


Kind regards
