How to interface Devasys USBI2C/IO interface board? (URGENT)

[furmanlim]

I have a project which is doing graphic user interface(GUI). I had bought a device (can refer to www.devasys.com - USBI2C/IO interface board) as data acquisition hardware between hardware and PC(GUI). But, I don't know how to use labview software to communicate with this device. Can you all guys help me? Appreicate your reply and thank you very much.

Devasys has a driver you can download. This is a DLL interface and you will need to use the LabVIEW Call Library Nodes to access this DLL. While I have a Devasys board laying around here at the moment, I have no time to develop a LabVIEW driver for it in the short term. We ended up using a different USB to I2C interface for that particular project, due to delivery delays from Devasys. I don't expect it to be a major problem to do such a driver but some basic DLL knowledge will be necessary. Search here on the developer exchange for DLL programming. There are many resources you can and probably should at least partly read, to get this done yourself.

Hi Rolf,

I know time has passed since your answer and this is acutally why I'm asking. Does the same  technique still works with latest LabView 8.6?

I'm especially interested in integrating the new Devasys like board  called SUB-20. It also has DLL provided and API sims to be simple and straighforward.

Here is information about board: SUB-20 Multi Interface USB Adapter

And here is API documentation: SUB-20 API

Thanks.

The Call Library Node is still there and has additioanl features in comparison to 4 years ago. So yes the same still applies but the job may have gotten even a bit easier now.

Just in case if somebody else interested, after my negotiations with SUB-20 manufacturing company they have released their own LabVIEW support module:

SUB-20-LabVIEW-0.1.zip

Good afternoon!
Please download the archive with the LABVIEW project again.
The link to the SUB-20-LabVIEW-0.1.zip archive in the previous message is no longer available.
