DlPortIO issues

I'm trying to set up parallel port triggering for an EEG study.

When I try to run it I get "Could not import DLportIO driver, parallel
Ports not available"

I found the new link to http://winfordeng.com/support/download.php to
download this, which I did. But when I go to install it, I get the
following error:

"The Win 16 subsystem has insufficient resources to continue running"

I know this isn't a problem with psychopy specifically, but I was
wondering if anyone has set up parallel port triggering on Win XP and
has any suggestions about what might be going wrong.

Thanks!

Emily

I solved this (or at least got this to work).

If you're having similar issues with DLportIO and the downloaded driver, you can download another driver version here:

(actual download link:) http://lcdhype.condense.de/index.php?s=64581fdaee6296656a1fadf18811a90b&act=Attach&type=post&id=19986&index=0

Seems a little sketchy, but I added it to C:\Windows\System32 and was then able to trigger through the parallel port without any issues.

Just for the record ..I too tried different ways of controlling
parallel port with Python on Windows (Xp 32 bit). The easiest way I
found was with Inpout32.dll.
(http://logix4u.net/Legacy_Ports/Parallel_Port/Inpout32.dll_for_Windows_98/2000/NT/XP.html)

Just download the dll, put it in system32 folder. Then from python:

from ctypes import windll
p = windll.inpout32
p.Inp32(0x378) #default 255(all high) on my pc
p.Out32(0x378, 0) #put all low on port 2-9

The address 0x378 might be different on your machine, open
System->Hardware->Device Manager->Ports->ECP Printer
Port->Properties->Resources, use the first number as your address.
