interrupt resource conflict

[ezacherl]

I am trying to use a PCI to PCMCIA adapter in my desktop to run the PCMCIA-CAN module that I have. I get an interrupt resource conflict error in the NI software, but windows XP thinks it is fine.  I have the most recent drivers, version 2.5.2 I think. I also tried manually changing the interrupt settings for the device, and that did not help.

Hello ezacherl,

I believe the only solution to the problem is to assign the interrupt manually.  You can look at this link to see if you proceed the same way.  If this still does not work, can you please post a screenshot of the IRQ settings in your PC.  

Also, the current version of the driver is NI-CAN 2.6.1, but I don't think that will make a difference in this case.  Also, we do have PCI-CAN cards that may simplify your system.  Of course, you may have a very good reason to use the PCMCIA-CAN.

Let me know if any of this helps.  Have a great weekend.

I am still having problems even after I manually set the interrupt and memory allocation. Here is the screenshot as you requested.

Hello Ezacherl,

When Windows detects the PCI-PCMCIA adapter, it treats it as another PCI device in the system.  Windows assigns an interrupt to the PCI device.  The NI-PCMCIA boards also needs an interrupt line.  In this way, the PCI interrupt line is shared between the PCMCIA device and the adapter.  The driver will throw an error because the NI-PCMCIA board needs a dedicated interrupt line.

At this point, I think you will need to modify the hardware in your system. A PCMCIA Adapter that has worked for some customers.  These types of adapters add a software layer that helps windows assign 2 interrupts to the device.  You can also look at our PCI-CAN devices.

I apologize for the inconvenience.  Please let me know if you have any further questions.
