In_Port.vi, Out_Port.vi

[jonsakai]

I am attempting to read data from a PCI board (for a JR3 force/moment sensor). The base address for my card is 0xFE000000, and I know how to access the offsets for each different data value that I'm interested in.

I'm running LabVIEW 7.1 on Win XP, so I installed the AccessHW "fix", and attempted to use In_Port.vi to read from the card. I think that I am reading from the card (I'm seeing data output on some channels), but I'm getting "-1" at the addresses where there should be changing data. Does In_Port.vi work for NON-parallel port memory space? Does anyone have any recent experience with In_Port.

Thanks.

It sounds like what you are trying to do might be better accomplished by using the NI Measurement Hardware DDK (Driver Development Kit). It should be downloadable (I think). I have never used it, but the short presentation that I saw about it makes me think it might make some of your problems easier to solve.

Hope that this helps,
Bob

It looks like you want to use NI-VISA to program a PCI device on register level, the following tutorial might help you to get it started:
