Parallel Port Wigglers PCI Cards and XP

We recently purchased a new Dell computer that does not have a parallel port built into the mother board. So far all of our attempts to use a PCI parallel port card have failed.

Is anyone using a Wigger on a PC with a PCI parallel port card?

Did you have any unusual problems getting it to work and how did you solve them?

If you do have it working, what brand of PCI parallel port card did you use?

We have tried a SiG and another unknown brand.

Thank you for any help you can provide.

I've come to the conclusion that it is _impossible_ to perform embedded development with parallel port-connected emulators, etc. using legacy-free PCs. I keep old machines, and SPARE old machines, lying around specifically for this reason.

I've had exactly the same sorts of problems as you describe with hardware for several different micros, and in all cases the only solution I found was to upgrade to USB versions of the programmer/emulator hardware.

You didn't mention your intended application, but assuming it is a piece of equipement it is possible that you are running into a timing issue. My company purchased an emulator / compiler system back in

2002, which uses a parallel port dongle (gag - ack) for the compiler. In order to get it to work, it was necessary to run a utility that slowed the timing of the parallel port down and the faster the processor in the computer the larger the scaling factor had to be.

I had similar problems using a parallel port wiggler for Motorola DSP56F800 series micros. The solution was to change the parallel port from ECP to standard bi-directional mode. As far as I know this can only be done via the PCs BIOS settings. After making this change the wiggler worked fine.

Note he was talking about PCI cards, not onboard ports. The BIOS should have nothing to do with the behaviour of such a thing.

You need to be able to force the PCI parallel port to "Legacy Mode". This is often easier said than done. I managed it with a parallel card based on a chipset from Oxford Semiconductor. I did not get anywhare with the supplied drivers, but I found DOS based software on the Oxford Semiconductor site, with which I could force the chipset to be mapped to the "Legacy ports". Windows then picked up the card as a legacy port, and I could use it for wigglers etc. I suspect if you can find cards that officially support DOS, it would work.

Recently i installed one for use with HASP, to in the driver there was the possibility to change these settings in the driver under devices

For PC's without a parallel port you need to install a PCI card or use an external device. If you install a PCI card you will find (as I did), that the BIOS settings need adjusting. I installed a Lava PCI card and after emailing the manufacturer I ended up changing the BIOS settings to get it to work.

So, in this case the BIOS did indeed help to configure the PCI card.

I don't have a wiggler, but my embedded systems are connected to the host via parallel ports for cross debugging. To be able to connect 3 systems at the same time, I added a PCI card from SUNIX

Downloading over the SUNIX ports is faster than over my legacy LPT1 port on the motherboard. The SUNIX ports support Centronics, ECP, EPP, etc. I quite happy with this card.

This may be slightly off topic, but I have Ti's XDS510PP (the old one without plus), and I have problem running it on newer Intel machines that have P4 core. It works on all AMD machines and on intel P3 machines and older. I have tried several motherboard/CPU configurations/BIOS setting to come to this conclusion.

So DOM maybe it is processor and not the port card.

To Noway2: You speak of utility that can slow down PP speed. Can you share it name and where could I obtain it?
