Driver for custom register based ISA board

[AP2006]

Is it possible to write LabView driver for a register based custom ISA board using low level register access VISA functions?

Hello AP2006,

To answer this question we need a few more details.  What operating system are you trying to develop for and what version of LabVIEW do you want to use?

Thank you for responding. I use Windows 2000 Pro or Windows XP and LabView 6.1. Computer is Advantech industrial computer with passive backplane consisting of ISA and PCI slots.

Hello AP2006,

I do not think you will be able to use VISA for this purpose, however there is a KnowledgeBase that may help you.  Take a look at the KB Accessing Hardware Registers and Physical Memory in Windows NT/2000/XP with LabVIEW.  I hope this answers your question.

Let us know if you have any more questions about this.

Is the custom board already designed and built? With pci, you can use VISA quite easily. See http://zone.ni.com/devzone/conceptd.nsf/webmain/ADF3152837E2B4A486256B5600642AC7 .

Unfortunately this is an old board, being manufactured for number of years. It was used successfully with LabWindows. I will be looking at accessing the board registers using CVI developed in LabVindows, but I do not know C...
