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 [article no longer available].  I hope this answers your question.

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

Thank you. I will try it and let you know.

Is the custom board already designed and built? With pci, you can use VISA quite easily. See https://www.ni.com/docs/en-US/bundle/ni-visa/page/using-visa-driver-wizard-to-program-pxipci.html .

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...
