New device driver

[cschneider]

Hi, I have a PCI-card which comes with its own DLL to control the functionality. As the functions are very similar to functions that can be provided by VISA (Open, Read, Write, Close), I want to write a new driver that can be controlled by VISA-Vis. I already found the article about the "Create new instrument driver wizard" to create own drivers for PCI-cards if you know the registers of the card...these registers, I don't know. Can I control the device with VISA, i. e. write a own driver to make the device VISA-compatible by using the DLL provided by the manufacturer??Thanks in advanceChristian

If it came with a DLL then you need to use Call Library Function to call the functions in the DLL. It doesn't make much sense to try to use VISA to control the device through its registers (assuming you actually could), as you'd basically be rewriting the DLL yourself, and what's the point of that?
